Tiger II is the common name of a German heavy tank of the Second World War. The final official German designation wasPanzerkampfwagen Tiger Ausf. B,  often shortened to Tiger B. The ordnance inventory designation was Sd.Kfz.182.It is also known under the informal name Königstiger  (the German name for the “Bengal tiger”), often semi-literally translated as the King Tiger or Royal Tiger by Allied soldiers.

The design followed the same concept as the Tiger I, but was intended to be even more formidable. The Tiger II combined the thick armor of the Tiger I with the sloped armor used on the Panther medium tank. The tank weighed almost seventymetric tons, was protected by 100 to 180 mm (3.9 to 7.1 in) of armor to the front, and was armed with the long barreled8.8 cm Kampfwagenkanone 43 L/71 gun. The chassis was also the basis for the Jagdtiger turretless tank destroyer.

The Tiger II was issued to heavy tank battalions of the Army (Schwere Heerespanzerabteilung – abbreviated s.H.Pz.Abt) and the Waffen-SS (s.SS.Pz.Abt). It was first used in combat with s.H.Pz.Abt. 503 during the Normandy campaign on 11 July 1944; on the Eastern Front the first unit to be outfitted with Tiger IIs was the s.H.Pz.Abt. 501 which by 1 September 1944 listed 25 Tiger IIs operational.

Tiger I is the common name of a German heavy tank developed in 1942 and used in World War II. The final official German designation was Panzerkampfwagen VI Tiger Ausf.E, often shortened to Tiger. It was an answer to the unexpectedly impressive Soviet armour encountered in the initial months of the Axis invasion of the Soviet Union, particularly the T-34 and the KV-1. The Tiger I gave the Wehrmacht its first tank mounting the 88 mm gun, in its first armoured fighting vehicle-dedicated version, the (KwK 36). During the course of the war, the Tiger I saw combat on all German battlefronts. It was usually deployed in independent tank battalions, which proved to be quite formidable.

While the Tiger I was feared by many of its opponents, it was over-engineered, using expensive materials and labour intensive production methods. Only 1,347 were built between August 1942 and August 1944. The Tiger was prone to certain types of track failures and immobilizations, and limited in range by its high fuel consumption. It was, however, generally mechanically reliable, but expensive to maintain. It was also difficult to transport, and vulnerable to immobilization when mud, ice and snow froze between its overlapping and interleaved road wheels in winter weather conditions, often jamming them solid. In 1944, production was phased out in favour of the Tiger II.

The tank was given its nickname “Tiger” by Ferdinand Porsche, and the Roman numeral was added after the later Tiger II entered production. The initial official German designation was Panzerkampfwagen VI Ausführung H (‘Panzer VI version H’, abbreviated PzKpfw VI Ausf. H), with ordnance inventory designation SdKfz 182, but the tank was redesignated asPzKpfw VI Ausf. E in March 1943, with ordnance inventory designation SdKfz 181.

Today, only a handful of Tigers survive in museums and exhibitions worldwide. The Bovington Tank Museum’s Tiger 131 is currently the only one restored to running order.

BATTLE OF BULGE

German troops advancing past abandoned American equipment

German leader Adolf Hitler felt that his mobile reserves allowed him to mount one major offensive. Although he realised nothing significant could be accomplished in the Eastern Front, he still believed an offensive against the Western Allies, whom he considered militarily inferior to the Red Army, would have some chances of success.[38] Hitler believed he could split the Allied forces and compel the Americans and British to settle for a separate peace, independent of the Soviet Union.  Success in the west would give the Germans time to design and produce more advanced weapons (such as jet aircraft, new U-boat designs and super-heavy tanks) and permit the concentration of forces in the east. After the war ended, this assessment was generally viewed as unrealistic, given Allied air superiority throughout Europe and their ability to continually disrupt German offensive operations.

Given the reduced manpower of their land forces at the time, the Germans believed the best way to seize the initiative would be to attack in the West against the smaller Allied forces rather than against the vast Soviet armies. Even theencirclement and destruction of entire Soviet armies, an unlikely outcome, would still have left the Soviets with a numerical superiority.

Several senior German military officers, including Field Marshal Walter Model and von Rundstedt, expressed concern as to whether the goals of the offensive could be realized. They offered alternative plans, but Hitler would not listen. The plan banked on unfavorable weather, including heavy fog and low-lying clouds, which would minimize the Allied air advantage.  Hitler originally set the offensive for late November, before the anticipated start of the Russian winter offensive.

In the west supply problems began significantly to impede Allied operations, even though the opening of the port of Antwerp in late November improved the situation somewhat. The positions of the Allied armies stretched from southern France all the way north to the Netherlands. German planning for the counteroffensive rested on the premise that a successful strike against thinly-manned stretches of the line would halt Allied advances on the entire Western Front.

Several plans for major Western offensives were put forward, but Oberkommando der Wehrmacht (High Command of the Armed Forces, or OKW) quickly concentrated on two. A first plan for an encirclement maneuver called for a two-pronged attack along the borders of the U.S. forces around Aachen, hoping to encircle the U.S. Ninth Army and leave the German forces again in control of the excellent defensive grounds where they had fought the U.S. to a standstill just weeks before. A second plan called for a classic blitzkrieg attack through the weakly defended Ardennes Mountains—mirroring the successful German offensive there during the Battle of France in 1940—aimed at splitting the armies along the U.S.—British lines and capturing Antwerp.

Hitler chose the second plan, believing a successful encirclement would have little impact on the overall situation and finding the prospect of splitting the Anglo-American armies more appealing. The disputes between Montgomery and Patton were well known, and Hitler hoped he could exploit this perceived disunity. If the attack were to succeed in capturing Antwerp, four complete armies would be trapped without supplies behind German lines.

Both plans centered on attacks against the American forces. Hitler believed the Americans were incapable of fighting effectively, and that the American home front was likely to crack upon hearing of a decisive American loss.

Tasked with carrying out the operation were Generalfeldmarschall (Field Marshal) Walther Model, the commander of German Army Group B (Heeresgruppe B), and Field MarshalGerd von Rundstedt, the overall commander of the German Army Command in the West (Oberbefehlshaber West), who had moved his base of operations to Kransberg Castle.

Model and von Rundstedt both believed aiming for Antwerp was too ambitious, given Germany’s scarce resources in late 1944. At the same time they felt that maintaining a purely defensive posture (as had been the case since Normandy) would only delay defeat, not avert it. They thus developed alternative, less ambitious plans that did not aim to cross theMeuse River; Model’s being Unternehmen Herbstnebel (Operation Autumn Mist) and von Rundstedt’s Fall Martin (“Plan Martin”). The two field marshals combined their plans to present a joint “small solution” to Hitler, who rejected it in favor of his “big solution”.

OKW decided by mid-September, at Hitler’s insistence, that the offensive would be mounted in the Ardennes, as was done in 1940. Many German generals objected, but the offensive was planned and carried out anyway. In 1940 German forces had passed through the Ardennes in three days before engaging the enemy, but the 1944 plan called for battle in the forest itself. The main forces were to advance westward to the Meuse River, then turn northwest for Antwerp and Brussels. The close terrain of the Ardennes would make rapid movement difficult, though open ground beyond the Meuse offered the prospect of a successful dash to the coast.

Four armies were selected for the operation. First was the Sixth Panzer Army, under SS General Sepp Dietrich—newly created on 26 October 1944, it incorporated the most senior and the most experienced formation of the Waffen-SS: the 1st SS Panzer DivisionLeibstandarte Adolf Hitler as well as the 12th SS Panzer Division Hitlerjugend. The 6th Panzer Army was designated the northernmost attack force, having its northernmost point on the pre-attack battlefront nearest the German town of Monschau. It was entrusted with the offensive’s primary objective—capturing Antwerp.

The Fifth Panzer Army under General Hasso von Manteuffel was assigned to the middle attack route with the objective of capturing Brussels.

The Seventh Army, under General Erich Brandenberger, was assigned to the southernmost attack, having its southernmost point on the pre-attack battlefront nearest the Luxembourg town of Echternach, with the task of protecting the flank. This Army was made up of only four infantry divisions, with no large-scale armored formations to use as a spearhead unit. As a result, they made little progress throughout the battle.

Also participating in a secondary role was the Fifteenth Army, under General Gustav-Adolf von Zangen. Recently brought back up to strength and re-equipped after heavy fighting during Market Garden, it was located on the far north of the Ardennes battlefield and tasked with holding U.S. forces in place, with the possibility of launching its own attack given favorable conditions.

For the offensive to be successful, four criteria were deemed critical: the attack had to be a complete surprise; the weather conditions had to be poor to neutralize Allied air superiority and the damage it could inflict on the German offensive and its supply lines; the progress had to be rapid—-the Meuse River, halfway to Antwerp, had to be reached by day 4; and Allied fuel supplies would have to be captured intact along the way because the Wehrmacht was short on fuel. The General Staff estimated they only had enough fuel to cover one-third to one-half of the ground to Antwerp in heavy combat conditions.

The plan originally called for just under 45 divisions, including a dozen panzer and panzergrenadierdivisions forming the armored spearhead and various infantry units to form a defensive line as the battle unfolded. By this time, however, the German Army suffered from an acute manpower shortage and the force had been reduced to around 30 divisions. Although it retained most of its armor, there were not enough infantry units because of the defensive needs in the East. These 30 newly rebuilt divisions used some of the last reserves of the German Army. Among them were Volksgrenadier units formed from a mix of battle-hardened veterans and recruits formerly regarded as too young or too old to fight. Training time, equipment and supplies were inadequate during the preparations. German fuel supplies were precarious—those materials and supplies that could not be directly transported by rail had to be horse-drawn to conserve fuel, and the mechanized and panzer divisions would depend heavily on captured fuel. As a result, the start of the offensive was delayed from 27 November to 16 December.

Before the offensive the Allies were virtually blind to German troop movement. During the liberation of France, the extensive network of the French resistance had provided valuable intelligence about German dispositions. Once they reached the German border, this source dried up. In France, orders had been relayed within the German army using radio messages enciphered by the Enigma machine, and these could be picked up and decrypted by Allied code-breakers headquartered at Bletchley Park, to give the intelligence known as ULTRA. In Germany such orders were typically transmitted using telephone and teleprinter, and a special radio silence order was imposed on all matters concerning the upcoming offensive.  The major crackdown in the Wehrmacht after the 20 July plot to assassinate Hitler resulted in much tighter security and fewer leaks. The foggy autumn weather also prevented Allied reconnaissance aircraft from correctly assessing the ground situation. German units assembling in the area were even issued charcoal instead of wood for cooking fires to cut down on smoke and reduce chances of Allied observers deducing a troop build up was underway. 

For these reasons Allied High Command considered the Ardennes a quiet sector, relying on assessments from their intelligence services that the Germans were unable to launch any major offensive operations this late in the war. What little intelligence they had led the Allies to believe precisely what the Germans wanted them to believe-–that preparations were being carried out only for defensive, not offensive, operations. In fact, because of the Germans’ efforts, the Allies were led to believe that a new defensive army was being formed around Düsseldorf in the northern Rhine, possibly to defend against British attack. This was done by increasing the number of flak batteries in the area and the artificial multiplication of radio transmissions in the area. The Allies at this point thought the information was of no importance. All of this meant that the attack, when it came, completely surprised the Allied forces. Remarkably, the U.S. Third Army intelligence chief, Colonel Oscar Koch, the U.S. First Army intelligence chief and the SHAEF intelligence officer all correctly predicted the German offensive capability and intention to strike the U.S. VIII Corps area. These predictions were largely dismissed by the U.S. 12th Army Group. Historian Patrick K. O’Donnell writes that on 8 December 1944, U.S. Rangers at great cost took Hill 400 during the Battle of the Hürtgen Forest. The next day GIs who relieved the Rangers reported a considerable movement of German troops inside the Ardennes in the enemy’s rear, but that no one in the chain of command connected the dots.

Because the Ardennes was considered a quiet sector, economy-of-force considerations led it to be used as a training ground for new units and a rest area for units that had seen hard fighting. The U.S. units deployed in the Ardennes thus were a mixture of inexperienced troops (such as the raw U.S. 99th and 106th “Golden Lions” Divisions), and battle-hardened troops sent to that sector to recuperate (the 28th Infantry Division).

Two major special operations were planned for the offensive. By October it was decided that Otto Skorzeny, the German commando who had rescued the former Italian dictatorBenito Mussolini, was to lead a task force of English-speaking German soldiers in “Operation Greif”. These soldiers were to be dressed in American and British uniforms and weardog tags taken from corpses and POWs. Their job was to go behind American lines and change signposts, misdirect traffic, generally cause disruption and seize bridges across the Meuse River between Liège and Namur. By late November, another ambitious special operation was added: Col. Friedrich August von der Heydte was to lead a Fallschirmjäger(paratrooper) Kampfgruppe in Operation Stösser, a night-time paratroop drop behind the Allied lines aimed at capturing a vital road junction near Malmedy.

German intelligence had set 20 December as the expected date for the start of the upcoming Soviet offensive, aimed at crushing what was left of German resistance on the Eastern Front and thereby opening the way to Berlin. It was hoped that Soviet leader Stalin would delay the start of the operation once the German assault in the Ardennes had begun and wait for the outcome before continuing.

After the 20 July plot attempt on Hitler’s life, and the close advance of the Red Army, Hitler and his staff had been forced to abandon the Wolfsschanze headquarters in East Prussia, in which they had coordinated much of the fighting on the Eastern Front. After a brief visit to Berlin, Hitler travelled on his Führersonderzug (train) to Giessen on 11 December, taking up residence in the Adlerhorst command complex, co-located with OB West’s base at Kransberg Castle. Believing in omens and the successes of his early war campaigns that had been planned at Kransberg, Hitler had chosen the site from which he had overseen the successful 1940 campaign against France and the Low Countries.

Von Rundstedt set up his operational headquarters near Limburg, close enough for the generals and Panzer Corps commanders who were to lead the attack to visit Adlerhorst on 11 December, travelling there in an SS-operated bus convoy. With the castle acting as overflow accommodation, the main party was settled into the Adlerhorst’s Haus 2 command bunker, including Gen. Alfred Jodl, Gen. Wilhelm Keitel, Gen. Blumentritt, von Manteuffel and S.S. Gen. Sepp Dietrich. Von Rundstedt then ran through the battle plan, while Hitler made one of his stoic speeches.

In a personal conversation on 13 December between Walther Model and Friedrich von der Heydte, who was put in charge of Operation Stösser, von der Heydte gave OperationStösser less than a 10% chance of succeeding. Model told him it was necessary to make the attempt: “It must be done because this offensive is the last chance to conclude the war favorably.”

Initial German assault

Situation on the Western Front as of 15 December 1944

On 16 December 1944, at 05:30, the Germans began the assault with a massive, 90-minute artillery barrage using 1,600 artillery pieces  across a 130-kilometre (80 mi) front on the Allied troops facing the 6th Panzer Army. The Americans’ initial impression was that this was the anticipated, localized counterattack resulting from the Allies’ recent attack in the Wahlerscheid sector to the north, where the 2nd Division had knocked a sizable dent in the Siegfried Line. In the northern sector Dietrich’s 6th Panzer Army was held up for almost 24 hours by a single reconnaissance platoon and four U.S. Forward Artillery Observers dug in on a ridge overlooking a key road intersection in the village of Lanzerath. They then assaulted Losheim Gap and Elsenborn Ridge in an effort to break through to Liège and Antwerp.

Heavy snowstorms engulfed parts of the Ardennes area. While having the desired effect of keeping the Allied aircraft grounded, the weather also proved troublesome for the Germans because poor road conditions hampered their advance. Poor traffic control led to massive traffic jams and fuel shortages in forward units.

In the center, von Manteuffel’s Fifth Panzer Army attacked towards Bastogne and St. Vith, both road junctions of great strategic importance. In the south, Brandenberger’s Seventh Army pushed towards Luxembourg in its efforts to secure the flank from Allied attacks. Only one month before 250 members of the Waffen-SS had unsuccessfully tried to recapture the town of Vianden with its castle from the Luxembourgish resistance during the Battle of Vianden.

attack’s on south east asia

British, Australian and Dutch forces, already drained of personnel and matériel by two years of war with Germany, and heavily committed in the Middle East, North Africa and elsewhere, were unable to provide much more than token resistance to the battle-hardened Japanese. The Allies suffered many disastrous defeats in the first six months of the war. Two major British warships the HMS Repulseand HMS Prince of Wales were sunk by a Japanese air attack off Malaya on 10 December 1941.

Thailand, with its territory already serving as a springboard for the Malayan campaign, surrendered within 24 hours of the Japanese invasion. The government of Thailand formally allied itself with Japan on 21 December.

Hong Kong was attacked on 8 December and fell on 25 December 1941, with Canadian forces and the Royal Hong Kong Volunteers playing an important part in the defense. U.S. bases on Guam and Wake Island were lost at around the same time.

Following the 1 January 1942 Declaration by United Nations (the first official use of the term United Nations), the Allied governments appointed the British General Sir Archibald Wavell to the American-British-Dutch-Australian Command (ABDACOM), a supreme command for Allied forces in South East Asia. This gave Wavell nominal control of a huge force, albeit thinly spread over an area from Burma to the Philippines to northern Australia. Other areas, including India, Hawaii and the rest of Australia remained under separate local commands. On 15 January Wavell moved to Bandung in Java to assume control of ABDACOM.

Japanese battleships YamashiroFusōand Haruna (more distant)

In January, Japan invaded Burma, the Dutch East Indies, New Guinea, the Solomon Islands and captured Manila, Kuala Lumpur andRabaul. After being driven out of Malaya, Allied forces in Singapore attempted to resist the Japanese during the Battle of Singapore but surrendered to the Japanese on 15 February 1942; about 130,000 Indian, British, Australian and Dutch personnel became prisoners of war. The pace of conquest was rapid: Bali  and Timor  also fell in February. The rapid collapse of Allied resistance had left the “ABDA area” split in two. Wavell resigned from ABDACOM on 25 February, handing control of the ABDA Area to local commanders and returning to the post of Commander-in-Chief, India.

The Bombing of Darwin, Australia, 19 February 1942

Meanwhile, Japanese aircraft had all but eliminated Allied air power in South-East Asia[46] and were making attacks on northern Australia, beginning with a psychologically devastating but militarily insignificant attack on the city of Darwin  on 19 February, which killed at least 243 people.

At the Battle of the Java Sea in late February and early March, the Imperial Japanese Navy (IJN) inflicted a resounding defeat on the main ABDA naval force, under Admiral Karel Doorman.[47] The Dutch East Indies campaign subsequently ended with the surrender of Allied forces on Java[48] and Sumatra.[49]

In March and April, a powerful IJN carrier force launched a raid into the Indian Ocean. British Royal Navy bases in Ceylon were hit and the aircraft carrier HMS Hermes as well as other Allied ships were sunk. The attack forced the Royal Navy to withdraw to the western part of the Indian Ocean.  This paved the way for a Japanese assault on Burma and India.

Surrender of U.S. forces atCorregidor, Philippines, May 1942

In Burma the British, under intense pressure, made a fighting retreat from Rangoon to the Indo-Burmese border. This cut the Burma Road which was the western Allies’ supply line to the Chinese Nationalists. Cooperation between the Chinese Nationalists and the Communists had waned from its zenith at the Battle of Wuhan, and the relationship between the two had gone sour as both attempted to expand their area of operations in occupied territories. Most of the Nationalist guerrilla areas were eventually overtaken by the Communists. On the other hand, some Nationalist units were deployed to blockade the Communists and not the Japanese. Furthermore, many of the forces of the Chinese Nationalists were warlords allied to Chiang Kai-Shek, but not directly under his command. “Of the 1,200,000 troops under Chiang’s control, only 650,000 were directly controlled by his generals, and another 550,000 controlled by warlords who claimed loyalty to his government; the strongest force was the Szechuan army of 320,000 men. The defeat of this army would do much to end Chiang’s power. The Japanese exploited this lack of unity to press ahead in their offensives.

Filipino and U.S. forces resisted in the Philippines until 8 May 1942, when more than 80,000 soldiers were ordered to surrender. By this time, General Douglas MacArthur, who had been appointed Supreme Allied Commander South West Pacific, had retreated to the safer confines of Australia. The U.S. Navy, under Admiral Chester Nimitz, had responsibility for the rest of the Pacific Ocean. This divided command had unfortunate consequences for the commerce war, and consequently, the war itself.

ATTACK ON PEARL HARBOR

UTEE

The attack on Pearl Harbor  was a surprise military strike conducted by the Imperial Japanese Navy against theUnited States naval base at Pearl Harbor, Hawaii, on the morning of December 7, 1941 (December 8 in Japan). The attack led to the United States’ entry into World War II.

The attack was intended as a preventive action in order to keep the U.S. Pacific Fleet from interfering with military actions the Empire of Japan was planning in Southeast Asia against overseas territories of the United Kingdom, theNetherlands, and the United States. There were simultaneous Japanese attacks on the U.S.-held Philippines and on theBritish Empire in Malaya, Singapore, and Hong Kong.

From the standpoint of the defenders, the attack commenced at 7:48 a.m. Hawaiian Time. The base was attacked by 353  Japanese fighters, bombers and torpedo planes in two waves, launched from six aircraft carriers.[14] All eight U.S. Navy battleships were damaged, with four being sunk. All but one were later raised, and six of the eight battleships returned to service and fought in the war. The Japanese also sank or damaged three cruisers, three destroyers, an anti-aircraft training ship,  and one minelayer. 188 U.S. aircraft were destroyed; 2,402 Americans were killed and 1,282 wounded. Important base installations such as the power station, shipyard, maintenance, and fuel and torpedo storage facilities, as well as the submarine piers and headquarters building (also home of the intelligence section) were not attacked. Japanese losses were light: 29 aircraft and five midget submarines lost, and 65 servicemen killed or wounded. One Japanese sailor was captured.

The attack came as a profound shock to the American people and led directly to the American entry into World War II in both the Pacific and European theaters. The following day (December 8), the United States declared war on Japan. Domestic support for non-interventionism, which had been strong, disappeared. Clandestine support of Britain (e.g., the Neutrality Patrol) was replaced by active alliance. Subsequent operations by the U.S. prompted Germany and Italy to declare war on the U.S. on December 11, which was reciprocated by the U.S. the same day.

After the attack, several journalists, authors, and retired military personnel argued that parties high in the U.S. and British governments knew of the attack in advance and may have let it happen (or even encouraged it) with the aim of bringing America into war. However, this Pearl Harbor advance-knowledge conspiracy theory is rejected by most mainstream historians.

There were numerous historical precedents for unannounced military action by Japan. However, the lack of any formal warning, particularly while negotiations were still apparently ongoing, led President Franklin D. Roosevelt to proclaim December 7, 1941, “a date which will live in infamy”.

Due to the fact the attack happened without a declaration of war and without explicit warning, the attack on Pearl Harbor was judged by the Tokyo Trials to be a Japanese war crime.

The attack took place before any formal declaration of war was made by Japan, but this was not Admiral Yamamoto’s intention. He originally stipulated that the attack should not commence until thirty minutes after Japan had informed the United States that peace negotiations were at an end.  The Japanese tried to uphold the conventions of war while still achieving surprise, but the attack began before the notice could be delivered. Tokyo transmitted the 5,000-word notification (commonly called the “14-Part Message”) in two blocks to the Japanese Embassy in Washington, but transcribing the message took too long for the Japanese ambassador to deliver it in time. (In fact, U.S. code breakers had already deciphered and translated most of the message hours before he was scheduled to deliver it.)  The final part of the “14 Part Message” is sometimes described as a declaration of war. While it neither declared war nor severed diplomatic relations, it was viewed by a number of senior U.S government and military officials as a very strong indicator that negotiations were likely to be terminated  and that war might break out at any moment.  A declaration of war was printed on the front page of Japan’s newspapers in the evening edition of December 8, but not delivered to the U.S. government until the day after the attack.

For decades, conventional wisdom held that Japan attacked without any official warning of a break in relations only because of accidents and bumbling that delayed the delivery of a document hinting at war to Washington. In 1999, however, Takeo Iguchi, a professor of law and international relations at International Christian University in Tokyo, discovered documents that pointed to a vigorous debate inside the government over how, and indeed whether, to notify Washington of Japan’s intention to break off negotiations and start a war, including a December 7 entry in the war diary saying, “our deceptive diplomacy is steadily proceeding toward success.” Of this, Iguchi said, “The diary shows that the army and navy did not want to give any proper declaration of war, or indeed prior notice even of the termination of negotiations … and they clearly prevailed

OPERATION BARBAROSSA

OPERATION BARBAROSSA

Operation Barbarossa was beginning in 22 June 1941, was the code name for Germany’s invasion of the Soviet Union during World War II.Over four million soldiers of the Axis powersinvaded the USSR along a 2,900 km (1,800 mi) front, the largest invasion in the history of warfare. In addition to troops,Barbarossa used 600,000 motor vehicles and 750,000 horses. The ambitious operation was driven by Adolf Hitler’s persistent desire to conquer the Soviet territories as embodied in Generalplan Ost. It marked the beginning of the pivotal phase in deciding the victors of the war. The German invasion of the Soviet Union caused a high rate of fatalities: 95% of all German Army casualties that occurred from 1941 to 1944, and 65% of all Allied military casualties from the entire war.

Operation Barbarossa was named after Frederick Barbarossa, the medieval Holy Roman Emperor. The invasion was authorized by Hitler on 18 December 1940 (Directive No. 21) for a start date of 15 May 1941, but this would not be met, and instead the invasion began on 22 June 1941. Tactically, the Germans won resounding victories and occupied some of the most important economic areas of the Soviet Union, mainly in Ukraine.Despite these successes, the German offensivestalled on the outskirts of Moscow and was then pushed back by a Soviet counter offensive without having taken the city. The Germans could never again mount a simultaneous offensive along the entire strategic Soviet–German front.The Red Army repelled the Wehrmacht‘s strongest blow, and Adolf Hitler did not achieve the expected victory, but the Soviet Union’s situation remained dire.

Operation Barbarossa‘s failure led to Hitler’s demands for further operations inside the USSR, all of which eventually failed, such as continuing the Siege of Leningrad, Operation Nordlicht, and Operation Blue, among other battles on occupied Soviet territory.

Operation Barbarossa was the largest military operation in history in both manpower and casualties. Its failure was a turning point in the Third Reich’s fortunes. Most importantly, Operation Barbarossa opened up the Eastern Front, to which more forces were committed than in any other theater of war in world history. Regions covered by the operation became the site of some of the largest battles, deadliest atrocities, highest casualties, and most horrific conditions for Soviets and Germans alike—all of which influenced the course of both World War II and 20th-century history. The German forces captured over three million Soviet POWs in 1941, who were not granted the protection stipulated in the Geneva Conventions. Most of them never returned alive.Germany deliberately starved the prisoners to death as part of its “Hunger Plan”, i.e., the program to reduce the Eastern European population

Joseph Stalin’s own reputation as a brutal dictator contributed both to the Nazis’ justification of their assault and their faith in success. In the late 1930s, many competent and experienced military officers were killed in the Great Purge, leaving the Red Army weakened and leaderless. The Nazis often emphasized the Soviet regime’s brutality when targeting the Slavs with propaganda. German propaganda claimed the Red Army was preparing to attack them, and their own invasion was thus presented as a preemptive strike.

In the summer of 1940, when German raw materials crises and a potential collision with the Soviet Union over territory in the Balkans arose, an eventual invasion of the Soviet Union looked increasingly like Hitler’s only solution. While no concrete plans were yet made, Hitler told one of his generals in June that the victories in western Europe “finally freed his hands for his important real task: the showdown with Bolshevism”, although German generals told Hitler that occupying Western Russia would create “more of a drain than a relief for Germany’s economic situation.” The Führer anticipated additional benefits

The Germans had begun massing troops near the Soviet border even before the campaign in the Balkans had finished. By the third week in February 1941, 680,000 German troops were stationed on the Romanian-Soviet border. In preparation for the attack, Hitler moved 3.2 million German and about 500,000 Axis soldiers to the Soviet border, launched many aerial surveillance missions over Soviet territory, and stockpiled materiel in the East. The Soviets were still taken by surprise, mostly due to Stalin’s belief that the Third Reich was unlikely to attack only two years after signing the Molotov-Ribbentrop Pact. The Soviet leader also believed the Nazis would be likely to finish their war with Britain before opening a new front. He refused to believe repeated warnings from his intelligence services on the Nazi buildup, fearing the reports to be British misinformation designed to spark a war between Germany and the USSR.

Spy Dr. Richard Sorge gave Stalin the exact German launch date; Swedish cryptanalysts led by Arne Beurling also knew the date beforehand, but Sorge and other informers (e.g., from the Berlin Police department) had previously given different invasion dates which passed peacefully before the actual invasion. In addition, British intelligence gathering information through Ultra warned the Soviet Union of impending invasion several months prior to 22 June 1941.

The Germans set up deception operations, from April 1941, to add substance to their claims that Britain was the real target: Operations Haifisch and Harpune. These simulated preparations in Norway, the Channel coast and Britain. There were supporting activities such as ship concentrations, reconnaissance flights and training exercises. Some details of these bogus invasion plans were deliberately leaked.

German military planners also researched Napoleon’s failed invasion of Russia. In their calculations they concluded that there was little danger of a large-scale retreat of the Soviet army into the Russian interior, as it could not afford to give up the Baltic states, Ukraine, or the Moscow and Leningrad regions, all of which were vital to the Red Army for supply reasons and would thus have to be defended.

The strategy Hitler and his generals agreed on involved three separate army groups assigned to capture specific regions and cities of the Soviet Union. The main German thrusts were conducted along historical invasion routes. Army Group North was to march through the Baltics into northern Russia, and either take or destroy the city of Leningrad (nowSaint Petersburg). Army Group Center would advance to Smolensk and then Moscow, marching through what is now Belarus and the west-central regions of Russia proper. Army Group South was to strike the heavily populated and agricultural heartland of Ukraine, taking Kiev before continuing eastward over the steppes of the southern USSR to the Volgawith the aim of controlling the oil-rich Caucasus.

The postponement of Barbarossa from the initially planned date of 15 May to the actual invasion date of 22 June 1941 (a 38-day delay) occurred due to a combination of reasons; the Balkans Campaign required a divergence of troops and resources; insufficient logistics (preexisting and those incurred by the Balkans Campaign) hampered the preparations; and an unusually wet winter that kept rivers at full flood until late spring could have discouraged an earlier attack, even if it was unlikely to have happened before the end of the Balkans Campaign. The importance of the delay is still debated.

The Germans also decided to bring rear forces (mostly Waffen-SS units and Einsatzgruppen) into the conquered territories to counter any partisan activity in areas they controlled.

BATTLE OF BRITAIN

lufwaffeBattle_of_britain_air_observer

The Battle of Britain  is the name given to the Second World War air campaign waged by the German Air Force (Luftwaffe) against the United Kingdom during the summer and autumn of 1940. The name is derived from a famous speech delivered by Prime Minister Winston Churchill in the House of Commons: “… the Battle of France is over. I expect that the Battle of Britain is about to begin.”

The Battle of Britain was the first major campaign to be fought entirely by air forces, and was also the largest and most sustained aerial bombing campaign to that date. The objective of the campaign was to gain air superiority over the Royal Air Force (RAF), especially Fighter Command. From July 1940, coastal shipping convoys and shipping centres, such asPortsmouth, were the main targets; one month later the Luftwaffe shifted its attacks to RAF airfields and infrastructure. As the battle progressed the Luftwaffe also targeted aircraft factories and ground infrastructure. Eventually the Luftwaffe resorted to attacking areas of political significance and using terror bombing strategy.

The failure of Germany to achieve its objectives of destroying Britain’s air defences, or forcing Britain to negotiate anarmistice or an outright surrender, is considered its first major defeat and a crucial turning point in the Second World War. By preventing Germany from gaining air superiority, the battle ended the threat that Hitler would launch OperationSea Lion, a proposed amphibious and airborne invasion of Britain.

The Luftwaffe was devised to provide tactical support for the army on the battlefield. During the blitzkriegoffensives against Poland, Denmark and Norway and France and the Low Countries, the Luftwaffe had co-operated fully with the Wehrmacht. For the Battle of Britain however, the Luftwaffe had to operate in a strategic role, something for which it was unsuited. Its main task was to ensure air supremacy over southeast England, to pave the way for an invasion fleet.

The Luftwaffe regrouped after the Battle of France into three Luftflotten (Air Fleets) on Britain’s southern and northern flanks. Luftflotte 2, commanded by Generalfeldmarschall Albert Kesselring, was responsible for the bombing of southeast England and the London area. Luftflotte 3, under Generalfeldmarschall Hugo Sperrle, targeted the West Country, Wales, the Midlands, and northwest England. Luftflotte 5, led by GeneraloberstHans-Jürgen Stumpff from his headquarters in Norway, targeted the north of England and Scotland. As the battle progressed, command responsibility shifted, with Luftflotte 3 taking more responsibility for the night-timeBlitz attacks while the main daylight operations fell upon Luftflotte 2’s shoulders.

Initial Luftwaffe estimates were that it would take four days to defeat the RAF Fighter Command in southern England. This would be followed by a four-week offensive during which the bombers and long-range fighters would destroy all military installations throughout the country and wreck the British aircraft industry. The campaign was planned to begin with attacks on airfields near the coast, gradually moving inland to attack the ring of sector airfields defending London. Later reassessments gave the Luftwaffe five weeks, from 8 August to 15 September, to establish temporary air superiority over England. To achieve this goal, Fighter Command had to be destroyed, either on the ground or in the air, yet theLuftwaffe had to be able to preserve its own strength to be able to support the invasion; this meant that the Luftwaffe had to maintain a high “kill ratio” over the RAF fighters. The only alternative to the goal of air superiority was a terror bombing campaign aimed at the civilian population, but this was considered a last resort and it was (at this stage of the battle) expressly forbidden by Hitler.

The Luftwaffe kept broadly to this scheme, but its commanders had differences of opinion on strategy. Sperrle wanted to eradicate the air defence infrastructure by bombing it. His counterpart, Kesselring, championed attacking London directly—either to bombard the British government into submission or to draw RAF fighters into a decisive battle. Göring did nothing to resolve this disagreement between his commanders, and only vague directives were set down during the initial stages of the battle, with Göring seemingly unable to decide upon which strategy to pursue. He seemed at times obsessed with maintaining his own power base in the Luftwaffe and indulging his outdated beliefs on air fighting, which would later lead to tactical and strategic terrors.

BATTLE OF FRANCE

In the Second World War, the Battle of France, also known as the Fall of France, was the successful German invasion of France and the Low Countries, beginning on 10 May 1940, defeating primarily French forces. The battle consisted of two main operations. In the first, Fall Gelb (Case Yellow), German armoured units pushed through the Ardennes to cut off and surround the Allied units that had advanced into Belgium. When British and adjacent French forces were pushed back to the sea by the highly mobile and well organised German operation, the British government decided to evacuate the British Expeditionary Force (BEF) as well as several French divisions at Dunkirk in Operation Dynamo.

After the withdrawal of the BEF, Germany launched a second operation, Fall Rot (Case Red), which was commenced on 5 June. While the depleted French forces put up stiff initial resistance, German air superiority and armoured mobility overwhelmed the remaining French forces. German armour outflanked the Maginot Line and pushed deep into France with German forces arriving in an undefended Paris on 14 June. This caused a chaotic period of flight for the French government and effectively ended organized French military resistance. German commanders finally met with French officials on June 18 with the goal of the new French government being an armistice with Germany. Chief among the new government leaders was Marshal Philippe Pétain, newly appointed Prime Minister and one of the supporters of seeking an armistice with Germany.

On 22 June, an armistice was signed between France and Germany, which resulted in a division of France whereby Germany would occupy the north and west, Italy would control a small Italian occupation zone in the southeast, and an unoccupied zone, the zone libre, would be governed by the newly formed Vichy government led by Marshal Pétain. France remained under Axis occupation until the liberation of the country after the Allied landings in 1944.

Hitler had always fostered dreams about major military campaigns to defeat the Western European nations as a preliminary step to the conquest of territory in Eastern Europe, thus avoiding a two-front war. However, these intentions were absent from Führer-Directive N°6. This plan was firmly based on the seemingly more realistic assumption that Germany’s military strength would still have to be built up for several more years and that for the moment only limited objectives could be envisaged. They were aimed at improving Germany’s ability to survive a long, protracted war in the West. Hitler ordered a conquest of the Low Countries to be executed at the shortest possible notice. This would stop France from occupying them first, and prevent Allied air power from threatening the vital German Ruhr Area. It would also provide the basis for a long-term air and sea campaign against Britain. There was no mention in the Führer-Directive of any immediate consecutive attack to conquer the whole of France, although as much as possible of the border areas in northern France should be occupied.

Hitler first proposed beginning the invasion of France on 25 October, but accepted that the date was likely unrealistic. On 5 November he proposed attacking on 12 November to Commander-in-chief of the Army Walther von Brauchitsch. The general replied that the military had not recovered from the Polish campaign; the motorised units had to recover, repairing the damage to their vehicles, and ammunition stocks were largely depleted. Von Brauchitsch offered to resign if Hitler did not change his mind; his resignation was refused but two days later Hitler postponed the attack, giving poor weather as the official reason for the delay.

On 27 January, von Manstein was relieved of his appointment as Chief of Staff of Army Group A and appointed commander of an army corps in Prussia, to begin his command inStettin on 9 February, a move instigated by Halder to reduce von Manstein’s influence.[29] Von Manstein’s indignant staff brought his case to Hitler’s attention. Hitler had, without any knowledge of von Manstein’s plan, suggested an attack focused at Sedan but had been persuaded to forget the idea as it was too risky. On 2 February, von Manstein’s plan was brought to his attention. On 17 February, Hitler summoned von Manstein, Generals Rudolf Schmundt (the German Army’s Chief of Personnel) and Alfred Jodl, the Chief of Operations at the OKW (the German armed forces’ supreme command), to attend a conference. Hitler sat and listened, abandoning his habits of interrupting and launching into monologues. In the end, he agreed to all of von Manstein’s suggestions. The next day, he ordered the plans to be changed in accordance with von Manstein’s ideas. They appealed to Hitler mainly because they offered some real hope of victory. Hitler recognised the breakthrough at Sedan only in tactical terms, whereas von Manstein saw it as a means to an end. He envisaged an operation to the English Channel and the encirclement of the Allied armies in Belgium, which, if carried out correctly, could have a favourable strategic outcome.

Halder had no intention of deviating from established doctrine by allowing an independent strategic penetration by the seven armoured divisions of Army Group A.Much to the outrage of Guderian, this element was at first completely removed from the new plan, Aufmarschanweisung N°4, Fall Gelb, issued on 24 February. However, Halder went through an “astonishing change of opinion”. Halder was criticised in the same way he had attacked von Manstein when he first suggested it. The bulk of the German officer corps was appalled by the plan, and they called him the “gravedigger of the Panzer force”.

Even when adapted to more conventional methods, the new plan provoked a storm of protest from the majority of German generals. They thought it utterly irresponsible to create a concentration of forces in a position where they could not possibly be sufficiently supplied, while such inadequate supply routes as there were could easily be cut off by the French. If the Allies did not react as expected, the German offensive could end in catastrophe. Their objections were ignored. Halder argued that, as Germany’s strategic position seemed hopeless anyway, even the slightest chance of a decisive victory outweighed the certainty of ultimate defeat implied by inaction.

INVASION OF POLAND

 Invasion of poland started in september 1 , 1939. the german code of this invasion is operation  fall weiss  (case white)

Germany had a substantial numeric advantage over Poland and had developed a significant military prior to the conflict. The Heer (army) had some 2,400 tanks organized into sixpanzer divisions, utilizing a new operational doctrine. It held that these divisions should act in coordination with other elements of the military, punching holes in the enemy line and isolating selected units, which would be encircled and destroyed. This would be followed up by less-mobile mechanized infantry and foot soldiers. The Luftwaffe (air force) provided both tactical and strategic air power, particularly dive bombers that disrupted lines of supply and communications. Together, the new methods were nicknamed “Blitzkrieg” (lightning war). Historian Basil Liddell Hart claimed “Poland was a full demonstration of the Blitzkrieg theory.”[40] Some other historians, however, disagree.

Aircraft played a major role in the campaign. Bombers also attacked cities, causing huge losses amongst the civilian population through terror bombing and strafing. The Luftwaffeforces consisted of 1,180 fighters, 290 Ju

87 Stuka dive bombers, 1,100 conventional bombers (mainly Heinkel He 111s and Dornier Do 17s), and an assortment of 550 transport and 350 reconnaissance aircraft. In total, Germany had close to 4,000 aircraft, most of them modern. A force of 2,315 aircraft was assigned to Weiss. Due to its prior participation in the Spanish Civil War, the Luftwaffe was probably the most experienced, best trained and best equipped air force in the world in 1939.

The September Campaign was devised by General Franz Halder, chief of the general staff, and directed by General Walther von Brauchitsch, the commander in chief of the upcoming campaign. It called for the start of hostilities before a declaration of war, and pursued a doctrine of mass encirclement and destruction of enemy forces. The infantry—far from completely mechanized but fitted with fast moving artillery and logistic support—was to be supported by Panzers and small numbers of truck-mounted infantry (the Schützen regiments, forerunners of the panzergrenadiers) to assist the rapid movement of troops and concentrate on localized parts of the enemy front, eventually isolating segments of the enemy, surrounding, and destroying them. The pre-war “armored idea” (which an American journalist in 1939 dubbed Blitzkrieg)—which was advocated by some generals, including Heinz Guderian—would have had the armor punching holes in the enemy’s front and ranging deep into rear areas; in actuality, the campaign in Poland would be fought along more traditional lines. This stemmed from conservatism on the part of the German high command, who mainly restricted the role of armor and mechanized forces to supporting the conventional infantry divisions.

Poland’s terrain was well suited for mobile operations when the weather cooperated; the country had flat plains with long frontiers totalling almost 5,600 km (3,500 mi), Poland’s long border with Germany on the west and north—facing East Prussia—extended 2,000 km (1,200 mi). Those had been lengthened by another 300 km (190 mi) on the southern side in the aftermath of the Munich Agreement of 1938. The German incorporation of Bohemia and Moravia and creation of the German puppet state of Slovakia meant that Poland’s southern flank was exposed.
