Battle of the Atlantic
The Battle of the Atlantic was the longest continuous military campaign in World War II, running from 1939 to the defeat of Germany in 1945. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany’s subsequent counter-blockade. It was at its height from mid-1940 through to the end of 1943. The Battle of the Atlantic pitted U-boats and other warships of the Kriegsmarine (German navy) and aircraft of the Luftwaffe (German Air Force) against the Royal Canadian Navy, Royal Navy, the United States Navy, and Allied merchant shipping. The convoys, coming mainly from North America and predominantly going to the United Kingdom and the Soviet Union, were protected for the most part by the British and Canadian navies and air forces. These forces were aided by ships and aircraft of the United States from September 13, 1941. The Germans were joined by submarines of the Italian Royal Navy (Regia Marina) after their Axis ally Italy entered the war on June 10, 1940.
As an island nation, the United Kingdom was highly dependent on imported goods. Britain required more than a million tons of imported material per week in order to be able to survive and fight. In essence, the Battle of the Atlantic was a tonnage war: the Allied struggle to supply Britain and the Axis attempt to stem the flow of merchant shipping that enabled Britain to keep fighting. From 1942 onwards, the Axis also sought to prevent the build-up of Allied supplies and equipment in the British Isles in preparation for the invasion of occupied Europe. The defeat of the U-boat threat was a pre-requisite for pushing back the Axis. The outcome of the battle was a strategic victory for the Allies—the German blockade failed—but at great cost: 3,500 merchant ships and 175 warships were sunk for the loss of 783 U-boats.
The name “Battle of the Atlantic” was coined by Winston Churchill in February 1941. It has been called the “longest, largest, and most complex” naval battle in history. The campaign started immediately after the European war began, during the so-called “Phoney War”, and lasted six years, until the German Surrender in May 1945. It involved thousands of ships in more than 100 convoy battles and perhaps 1,000 single-ship encounters, in a theater covering millions of square miles of ocean. The situation changed constantly, with one side or the other gaining advantage, as participating countries surrendered, joined, and even changed sides in the war, and as new weapons, tactics, counter-measures, and equipment were developed by both sides. The Allies gradually gained the upper hand, overcoming German surface raiders by the end of 1942 and defeating the U-boats by mid-1943, though losses due to U-boats continued until war’s end.
Battle of Belgium – 1940
The Battle of Belgium or Belgian Campaign, often referred to as the 18 Days’ Campaign in Belgium, formed part of the greater Battle of France, an offensive campaign by Germany during the Second World War. It took place over 18 days in May 1940 and ended with the German occupation of Belgium following the surrender of the Belgian Army.
On 10 May 1940, Germany invaded Luxembourg, the Netherlands, and Belgium under the operational plan Fall Gelb (Case Yellow). The Allied armies attempted to halt the German Army in Belgium, believing it to be the main German thrust. After the French had fully committed the best of the Allied armies to Belgium between 10 and 12 May, the Germans enacted the second phase of their operation, a break-through, or sickle cut, through the Ardennes, and advanced toward the English Channel. The German Army (Heer) reached the Channel after five days, encircling the Allied armies. The Germans gradually reduced the pocket of Allied forces, forcing them back to the sea. The Belgian Army surrendered on 28 May 1940, ending the battle.
The Battle of Belgium included the first tank battle of the war, the Battle of Hannut. It was the largest tank battle in history up to that date but was later surpassed by the battles of the North African campaign and the Eastern Front. The battle also included the Battle of Fort Eben-Emael, the first strategic airborne operation using paratroopers ever attempted.
The German official history stated that in the 18 days of bitter fighting, the Belgian Army were tough opponents, and spoke of the “extraordinary bravery” of its soldiers. The Belgian collapse forced the Allied withdrawal from continental Europe. The British Royal Navy subsequently evacuated Belgian ports during Operation Dynamo, allowing the British Army to escape and continue military operations. France reached its own armistice with Germany in June 1940. Belgium was occupied by the Germans until the autumn of 1944, when it was liberated by the Western Allies.
Battle of the Caucasus
The Battle of the Caucasus is a name given to a series of Axis and Soviet operations in the Caucasus area on the Eastern Front of World War II.
Battle of Kiev – 1943
The Second Battle of Kiev involved three strategic operations by the Soviet Red Army, and one operational counterattack by the Wehrmacht which took place between 3 October and 22 December 1943.
Following the Battle of Kursk, the Red Army launched Belgorod-Khar’kov Offensive Operation, pushing Erich von Manstein’s Army Group South back towards the Dnieper River. Stavka, the Soviet high command, ordered the Central Front and the Voronezh Front to force crossings of the Dnieper. When this was unsuccessful in October, the effort was handed over to the 1st Ukrainian Front, with some support from the 2nd Ukrainian Front. The 1st Ukrainian Front, commanded by Nikolai Vatutin, was able to secure bridgeheads north and south of Kiev.
Third Battle of Kharkov
The Third Battle of Kharkov was a series of battles on the Eastern Front of World War II, undertaken by the German Army Group South against the Red Army, around the city of Kharkov (or Kharkiv) between 19 February and 15 March 1943. Known to the German side as the Donets Campaign, and to in the Soviet Union as the Donbas and Kharkov operations, the German counter strike led to the recapture of the cities of Kharkov and Belgorod.
As the German Sixth Army was encircled in Stalingrad, the Red Army undertook a series of wider attacks against the rest of Army Group South. These culminated on 2 January 1943 when the Red Army launched Operation Star and Operation Gallop, which between January and early February broke German defenses and led to the Soviet recapture of Kharkov, Belgorod, Kursk, as well as Voroshilovgrad and Izium. The Soviet victories caused participating Soviet units to over-extend themselves. Freed on 2 February by the surrender of the German Sixth Army the Red Army’s Central Front turned its attention west and on 25 February expanded its offensive against both Army Group South and Army Group Center. Months of continuous operations, however, had taken a heavy toll on the Soviet forces and some divisions were reduced to 1,000–2,000 combat effective soldiers. On 19 February, Field Marshal Erich von Manstein launched his Kharkov counterstrike, using the fresh II SS Panzer Corps and two panzer armies.
The Wehrmacht flanked, encircled, and defeated the Red Army’s armored spearheads south of Kharkov. This enabled Manstein to renew his offensive against the city of Kharkov proper on 7 March. Despite orders to encircle Kharkov from the north the SS Panzer Corps instead decided to directly engage Kharkov on 11 March. This led to four days of house-to-house fighting before Kharkov was recaptured by the 1st SS Panzer Division on 15 March. The German forces recaptured Belgorod two days later, creating the salient which in July 1943 would lead to the Battle of Kursk. The German offensive cost the Red Army an estimated 90,000 casualties. The house-to-house fighting in Kharkov was also particularly bloody for the German SS Panzer Corps, which had approximately 4,300 men killed and wounded by the time operations ended in mid March.
Battle of Königsberg
The Battle of Königsberg, also known as the Königsberg Offensive, was one of the last operations of the East Prussian Offensive during World War II. In four days of violent urban warfare, Soviet forces of the 1st Baltic Front and the 3rd Belorussian Front captured the city of Königsberg – now Kaliningrad, Russia. The siege started in late January 1945 when the Soviets initially surrounded the city. There was heavy fighting for the overland connection between Königsberg and the port of Pillau, but by March 1945 Königsberg was hundreds of kilometres behind the main front line. The battle finished when the German garrison surrendered to the Soviets on 9 April after a three-day assault made their position untenable.
Battle of Leros
The Battle of Leros was the central event of the Dodecanese Campaign of the Second World War, and is widely used as an alternate name for the whole campaign. The Italian garrison in Leros was strengthened by British forces on 15 September 1943. The battle began with German air attacks on 26 September, continued with the landings on 12 November, and ended with the capitulation of the Allied forces four days later.
Battle of the Netherlands – 1940
The Battle of the Netherlands (Dutch: Slag om Nederland) was part of Case Yellow (German: Fall Gelb), the German invasion of the Low Countries (Belgium, Luxembourg, and the Netherlands) and France during World War II. The battle lasted from 10 May 1940 until the main Dutch forces surrendered on the 14th. Dutch troops in the province of Zealand continued to resist the Wehrmacht until 17 May when Germany completed its occupation of the whole nation.
The Battle of the Netherlands saw one of the first major uses of paratroopers to occupy crucial targets prior to ground troops reaching the area. The German Luftwaffe utilised paratroopers in the capture of several major airfields in the Netherlands in and around key cities such as Rotterdam and The Hague in order to quickly overrun the nation and immobilise Dutch forces.
The battle ended soon after the devastating bombing of Rotterdam by the German Luftwaffe and the subsequent threat by the Germans to bomb other large Dutch cities if Dutch forces refused to surrender. The Dutch General Staff knew it could not stop the bombers and surrendered in order to prevent other cities from suffering the same fate. The Netherlands remained under German occupation until 1945, when the last Dutch territory was liberated.
Battle of Belgium/Netherlands – 1944-45
The Allied advance from Paris to the Rhine was a phase in in the Western European Campaign of World War II.
This phase spans from the end of the Operation Overlord (25 August 1944) incorporating the German winter counter offensive through the Ardennes (commonly known as the Battle of the Bulge) up to the Allies preparing to cross the river Rhine in the early months of 1945. This roughly corresponds with the official U.S. European Theater of Operations Rhineland and Ardennes-Alsace campaigns.
Battle of Sedan
The Battle of Sedan or Second Battle of Sedan (12–15 May 1940) was a Second World War battle fought during the French Campaign. The battle was part of the German Wehrmacht’s operational plan codenamed Fall Gelb (Case Yellow) for an offensive through the hilly and heavily forested Ardennes, to encircle the Allied armies in Belgium and north-eastern France. German Army Group A crossed the Meuse river with the intention of capturing Sedan and pushing northwards towards the Channel coast, in order to entrap the Allied forces that were advancing east into Belgium, as part of the Allied Dyle Plan strategy.
Sedan was situated on the east bank of the Meuse River. Its capture would give the Germans a base from which to capture the Meuse bridges and cross the river. Should this occur, the German divisions could then advance across the open and undefended French countryside, beyond Sedan, and to the English Channel. On 12 May, Sedan was captured without resistance. In the following days, the Germans defeated the French defences surrounding Sedan on the west bank of the Meuse. This was largely achieved by the Luftwaffe. As a result of German bombing and low morale, the French defenders were unable to mount a coherent defence. The Germans captured the Meuse bridges at Sedan allowing them to pour forces including armour across the river. On 14 May, the Allied air forces, the Royal Air Force (RAF) and Armée de l’Air (French Air Force) tried to destroy the bridges, and prevent German reinforcements reaching the west bank. The Luftwaffe prevented them from doing so. In large air battles, the Allies suffered high losses which depleted Allied bomber strength in the campaign.
The crossing of the Meuse enabled the Germans to break into the strategic depths, or undefended rear, of the Allied front and to advance to the English Channel without significant opposition. The French attempted to launch counter-attacks against the German-held bridgeheads, from 15–17 May, but the offensives fell victim to delay and confusion. Five days after consolidating their bridgeheads at Sedan, on 20 May, the German Army reached the Channel. The victory at Sedan achieved the operational goal of Fall Gelb and encircled the strongest Allied armies, including the British Expeditionary Force. The resulting battles destroyed the remaining French army as an effective fighting force, and expelled the British Army from the continent, leading to the defeat of France in June 1940. The battle at Sedan was instrumental in the fall of France.
Bombing of Hamburg
The Allied bombing of Hamburg during World War II included numerous strategic bombing missions and diversion/nuisance raids. As a large port and industrial centre, Hamburg’s shipyards, U-boat pens, and the Hamburg-Harburg area oil refineries were attacked throughout the war.
The attack during the last week of July 1943, Operation Gomorrah, created one of the largest firestorms raised by the Royal Air Force and United States Army Air Forces in World War II, killing 42,600 civilians and wounding 37,000 in Hamburg and practically destroying the entire city. Before the development of the firestorm in Hamburg there had been no rain for some time and everything was very dry. The unusually warm weather and good conditions meant that the bombing was highly concentrated around the intended targets and also created a vortex and whirling updraft of super-heated air which created a 1,500-foot-high tornado of fire, a totally unexpected effect. Various other previously used techniques and devices were instrumental as well, such as area bombing, Pathfinders, and H2S radar, which came together to work with particular effectiveness. An early form of chaff, code named ‘Window’, was successfully used for the first time by the RAF – clouds of shredded tinfoil dropped by Pathfinders as well as the initial bomber stream – in order to completely cloud German radar. The raids inflicted severe damage to German armaments production in Hamburg.
The Demyansk Pocket (German: Festung Demjansk or Kessel von Demjansk; Russian: Демя́нский котёл) was the name given to the pocket of German troops encircled by the Red Army around Demyansk (Demjansk), south of Leningrad, during World War II on the Eastern Front. The pocket existed mainly from 8 February-21 April 1942. A much smaller pocket was simultaneously surrounded in Kholm, about 100 km (62 mi) to the southwest. These both resulted from the German retreat following their defeat during the Battle of Moscow.
The successful defence of Demyansk, achieved through the use of an airbridge, was a significant development in modern warfare. The pocket demanded an inordinate response on the part of the Soviets, stalling offensive actions elsewhere. Its success was a major contributor to the decision to try the same tactic during the Battle of Stalingrad.
The Dieppe Raid, also known as the Battle of Dieppe, Operation Rutter and, later, Operation Jubilee, was an Allied attack on the German-occupied port of Dieppe during the Second World War. The raid took place on the northern coast of France on 19 August 1942. The assault began at 5:00 a.m. and by 10:50 a.m. the Allied commanders were forced to call a retreat. Over 6,000 infantrymen, predominantly Canadian, were supported by The Calgary Regiment of the 1st Canadian Tank Brigade and a strong force of Royal Navy and smaller Royal Air Force landing contingents. It involved 5,000 Canadians, 1,000 British troops, and 50 United States Army Rangers.
Objectives included seizing and holding a major port for a short period, both to prove that it was possible and to gather intelligence. Upon retreat, the Allies also wanted to destroy coastal defences, port structures and all strategic buildings. The raid had the added objectives of boosting morale and demonstrating the firm commitment of the United Kingdom to open a western front in Europe.
Virtually none of these objectives were met. Allied fire support was grossly inadequate and the raiding force was largely trapped on the beach by obstacles and German fire. Less than 10 hours after the first landings, the last Allied troops had all been either killed, evacuated, or left behind to be captured by the Germans. Instead of a demonstration of resolve, the bloody fiasco showed the world that the Allies could not hope to invade France for a long time. Some intelligence successes were achieved, including electronic intelligence.
A total of 3,367 of the 6,086 men (almost 60%) who made it ashore were either killed, wounded, or captured. The Royal Air Force failed to lure the Luftwaffe into open battle, and lost 106 aircraft (at least 32 to flak or accidents), compared to 48 lost by the Luftwaffe. The Royal Navy lost 33 landing craft and one destroyer. The events at Dieppe influenced preparations for the North African (Operation Torch) and Normandy landings (Operation Overlord).
East Prussian Offensive
The East Prussian Offensive was a strategic offensive by the Red Army against the German Wehrmacht on the Eastern Front. It lasted from 13 January to 25 April 1945, though some German units did not surrender until 9 May. The Battle of Königsberg was a major part of the offensive, which ended in victory for the Red Army.
The East Prussian Offensive is known to German historians as the Second East Prussian Offensive. The First East Prussian Offensive (also known as the Gumbinnen Operation), took place from 16–27 October 1944, and was carried out by the 3rd Belorussian Front under General I.D. Chernyakhovsky as part of the Memel Offensive of the 1st Baltic Front. The Soviet forces took heavy casualties while penetrating 30–60 km (19–37 mi) into east-northern part of Poland, and the offensive was postponed until greater reserves could be gathered.
Occupation of Denmark
During most of World War II, Denmark was first a protectorate, then an occupied territory under Germany. On 9 April 1940, Germany invaded Denmark in Operation Weserübung and established a de facto protectorate over the country. On 29 August 1943, Germany placed Denmark under direct military occupation, which lasted until the Allied victory on 5 May 1945. Contrary to the situation in other countries under German occupation, most Danish institutions continued to function relatively normally until 1945. Both the Danish government and king remained in the country in an uneasy relationship between a democratic and a totalitarian system until the Danish government stepped down in a protest against the German demands to institute the death penalty for sabotage.
Just over 3,000 Danes died as a direct result of the occupation. (A further 4,000 Danish volunteers died fighting in the German army on the Eastern Front while 1,072 merchant sailors died in Allied service). Overall this represents a very low mortality rate when compared to other occupied countries and most belligerent countries.
An effective resistance movement developed by the end of the war, and most Danish Jews were rescued in 1943 when German authorities ordered their internment as part of the Holocaust.
In 2003, in a speech for the 60th anniversary of the end of the 1940–43 collaborationist government, Prime Minister Anders Fogh Rasmussen said that Denmark’s cooperation with Nazis was “morally unjustifiable”, which was the first public condemnation of the World War II era Danish leadership by a Danish leader.
Operation Bodenplatte (Baseplate), launched on 1 January 1945, was an attempt by the Luftwaffe to cripple Allied air forces in the Low Countries during the Second World War. The goal of Bodenplatte was to gain air superiority during the stagnant stage of the Battle of the Bulge so that the German Army and Waffen-SS forces could resume their advance. The operation was planned for 16 December 1944, but was delayed repeatedly due to bad weather until New Year’s Day, the first day that happened to be suitable.
Secrecy for the operation was so tight that not all German ground and naval forces had been informed of the operation and some units suffered casualties from friendly fire. British signals intelligence (Ultra) recorded the movement and buildup of German air forces in the region, but did not realise that an operation was imminent.
The operation achieved some surprise and tactical success, but was ultimately a failure. A great many Allied aircraft were destroyed on the ground but replaced within a week. Allied aircrew casualties were quite small, since the majority of Allied losses were empty planes sitting on the ground. The Germans, however, lost many pilots that they could not readily replace.
Post-battle analysis suggests only 11 of the Luftwaffe’s 34 air combat Gruppen made attacks on time and with surprise.The operation failed to achieve air superiority, even temporarily, while the German ground forces continued to be exposed to Allied air attack. Bodenplatte was the last large-scale strategic offensive operation mounted by the Luftwaffe during the war.
Operation Dragoon – Invasion of Southern France
Operation Dragoon was the Allied invasion of southern France on 15 August 1944, during World War II. The invasion was initiated via a parachute drop by the 1st Airborne Task Force, followed by an amphibious assault by elements of the United States Seventh Army, followed a day later by a force made up primarily of the French First Army. The landing caused the German Army Group G to abandon southern France and to retreat under constant Allied attacks to the Vosges Mountains. Despite being a large and complex military operation with a well-executed amphibious and airborne component, Operation Dragoon is not well known as it was overshadowed by the larger Operation Overlord, the invasion of Normandy (D-Day) two months earlier.
The objective of Operation Lila was to capture intact the units of the French fleet at Toulon, and was carried out by the 7th Panzer Division, augmented with units from other divisions. Four combat groups including two armoured groups and a motorcycle battalion from 2nd SS Panzer Division Das Reich were entrusted with the mission. To prevent the French naval units scuttling themselves, Marinedetachment Gumprich was assigned to one of the groups.
Operation Market Garden
Operation Market Garden (17–25 September 1944) was an unsuccessful Allied military operation, fought in the Netherlands and Germany in the Second World War. It was the largest airborne operation up to that time.
Field Marshal Montgomery’s goal was to force an entry into Germany over the Lower Rhine. He wanted to circumvent the northern end of the Siegfried Line and this required the operation to seize the bridges across the Maas (Meuse River) and two arms of the Rhine (the Waal and the Lower Rhine) as well as several smaller canals and tributaries. Crossing the Lower Rhine would allow the Allies to encircle Germany’s industrial heartland in the Ruhr from the north. It made large-scale use of airborne forces, whose tactical objectives were to secure the bridges and allow a rapid advance by armored units into Northern Germany.
Several bridges between Eindhoven and Nijmegen were captured at the beginning of the operation but Gen. Horrocks’ XXX Corps ground force advance was delayed by the demolition of a bridge over the Wilhelmina Canal, an extremely overstretched supply line at Son, and failure to capture the main road bridge over the river Waal before 20 September. At Arnhem, the British 1st Airborne Division encountered far stronger resistance than anticipated. In the ensuing battle, only a small force managed to hold one end of the Arnhem road bridge and after the ground forces failed to relieve them, they were overrun on 21 September. The rest of the division, trapped in a small pocket west of the bridge, had to be evacuated on 25 September. The Allies had failed to cross the Rhine in sufficient force and the river remained a barrier to their advance until offensives at Remagen, Oppenheim, Rees and Wesel in March 1945. The failure of Market Garden ended Allied expectations of finishing the war by Christmas 1944.
Operation Spring was an offensive operation conducted by II Canadian Corps during the Normandy campaign. The plan was intended to create pressure on the German forces operating on the British and Canadian front simultaneously to American offensive operations in their sector known as Operation Cobra, an attempt to break out from the Normandy lodgement. Specifically, Operation Spring was intended to capture Verrières Ridge and the towns on the south slope of the ridge. However, strong German defenses on the ridge, as well as strict adherence to a defensive doctrine of counterattacks, stalled the offensive on the first day, inflicting heavy casualties on the attacking forces, while preventing a breakout in the Anglo-Canadian sector.
The Prague uprising (Czech: Pražské povstání) was an attempt by the Czech resistance to liberate the city of Prague from German occupation during World War II. Events began on May 5, 1945, in the last moments of the war in Europe. The uprising went on until May 8, 1945, ending in a German victory and ceasefire. One day after the Germans conquered Prague, they surrendered on the arrival of the Red Army.
Siege of Breslau
The Battle of Breslau, also known as the Siege of Breslau, was a three-month-long siege of the city of Breslau in Lower Silesia, Germany (now Wrocław, Poland), lasting to the end of World War II in Europe. From 13 February 1945 to 6 May 1945, German troops in Breslau were besieged by the Soviet forces which encircled the city as part of the Lower Silesian Offensive Operation. The German garrison’s surrender on 6 May was followed by the surrender of all German forces two days after the battle.
Siege of Malta
The Siege of Malta was a military campaign in the Mediterranean Theatre of the Second World War. From 1940–42, the fight for the control of the strategically important island of Malta pitted the air forces and navies of Italy and Germany against the Royal Air Force and the Royal Navy.
The opening of a new front in North Africa in mid-1940 increased Malta’s already considerable value. British air and sea forces based on the island could attack Axis ships transporting vital supplies and reinforcements from Europe. General Erwin Rommel, in de facto field command of Axis forces in North Africa, recognized its importance quickly. In May 1941, he warned that “Without Malta the Axis will end by losing control of North Africa”.
The Axis resolved to bomb or starve Malta into submission, by attacking its ports, towns, cities, and Allied shipping supplying the island. Malta was one of the most intensively bombed areas during the war. The Luftwaffe and the Regia Aeronautica (Italian Royal Air Force) flew a total of 3,000 bombing raids over a period of two years in an effort to destroy RAF defenses and the ports. Success would have made possible a combined German—Italian amphibious landing (Operation Herkules) supported by German airborne forces (Fallschirmjäger). It was never carried out. In the event, Allied convoys were able to supply and reinforce Malta, while the RAF defended its airspace, though at great cost in material and lives.
By November 1942, the Axis had lost the Second Battle of El Alamein and the Allies had landed forces in Vichy French Morocco and Algeria under Operation Torch. The Axis diverted their forces to the Battle of Tunisia, and attacks on Malta were rapidly reduced. The siege effectively ended in November 1942.
In December 1942, air and sea forces operating from Malta went over to the offensive. By May 1943, they had sunk 230 Axis ships in 164 days, the highest Allied sinking rate of the war. The Allied victory played a major role in the eventual Allied success in North Africa.
Siege of Sevastopol 1941–42
The Siege of Sevastopol also known as the Defence of Sevastopol took place on the Eastern Front of the Second World War. The campaign was fought by the Axis powers of Germany, Romania, and Italy against the Soviet Union for control of Sevastopol, a port in the Crimea on the Black Sea. On 22 June 1941 the Axis invaded the Soviet Union during Operation Barbarossa. Axis land forces reached the Crimea in the autumn of 1941 and overran most of the area. The only objective not in Axis hands was Sevastopol. Several attempts were made to secure the city in October and November 1941. A major attack was planned for late November, but heavy rains delayed the Axis attack until 17 December 1941. Under the command of Erich von Manstein, Axis forces were unable to capture Sevastopol during this first operation. Soviet forces launched an amphibious landing on the Crimean peninsula at Kerch in December 1941 to relieve the siege and force the Axis to divert forces to defend their gains. The operation saved Sevastopol for the time being, but the bridgehead in the eastern Crimea was eliminated in May 1942.
After the failure of their first assault on Sevastopol, the Axis opted to conduct siege warfare until the middle of 1942, at which point they attacked the encircled Soviet forces by land, sea, and air. On 2 June 1942, the Axis began this operation, codenamed Störfang (Sturgeon Catch). The Soviet Red Army and Black Sea Fleet held out for weeks under intense Axis bombardment. The German Air Force (Luftwaffe) played a vital part in the siege. The Luftwaffe made up for a shortage of Axis artillery, providing highly effective aerial bombardment in support of the ground forces. Finally, on 4 July 1942, the remaining Soviet forces surrendered and the Axis seized the port. Both sides had suffered considerable losses during the siege and attack.
With the Soviet forces neutralised, the Axis refocused their attention on the major summer campaign of that year, Operation Blue and their advance to the Caucasus oil fields.
The Tunisia Campaign (also known as the Battle of Tunisia) was a series of battles that took place in Tunisia during the North African Campaign of the Second World War, between Axis and Allied forces. The Allies consisted of British Imperial Forces, including Polish and Greek contingents, with American and French corps. The battle opened with initial success by the German and Italian forces, but the massive supply and numerical superiority of the Allies led to the Axis’s complete defeat. Over 230,000 German and Italian troops were taken as prisoners of war, including most of the Afrika Korps.
