the war against germanyAfter securing the neutrality of the Soviet Union (through the August 1939 German-Soviet Pact of nonaggression), Germany started World War II by invading Poland on September 1, 1939. Britain and France responded by declaring war on Germany on September 3. Within a month, Poland was defeated by a combination of German and Soviet forces and was partitioned between Nazi Germany and the Soviet Union.
The relative lull in fighting which followed the defeat of Poland ended on April 9, 1940, when German forces invaded Norway and Denmark. On May 10, 1940, Germany began its assault on western Europe by invading the Low Countries (Netherlands, Belgium, and Luxembourg), which had taken neutral positions in the war, as well as France. On June 22, 1940, France signed an armistice with Germany, which provided for the German occupation of the northern half of the country and permitted the establishment of a collaborationist regime in the south with its seat in the city of Vichy. With German encouragement, the Soviet Union occupied the Baltic states in June 1940 and formally annexed them in August 1940. Italy, a member of the Axis (countries allied with Germany), joined the war on June 10, 1940. From July 10 to October 31, 1940, the Nazis waged, and ultimately lost, an air war over England, known as the Battle of Britain. After securing the Balkan region by invading Yugoslavia and Greece on April 6, 1941, the Germans and their allies invaded the Soviet Union on June 22, 1941, in direct violation of the German-Soviet Pact. In June and July 1941, the Germans also occupied the Baltic states. Soviet leader Joseph Stalin then became a major wartime Allied leader, in opposition to Nazi Germany and its Axis allies. During the summer and autumn of 1941, German troops advanced deep into the Soviet Union, but stiffening Red Army resistance prevented the Germans from capturing the key cities of Leningrad and Moscow. On December 6, 1941, Soviet troops launched a significant counteroffensive that drove German forces permanently from the outskirts of Moscow. One day later, on December 7, 1941, Japan (one of the Axis powers) bombed Pearl Harbor, Hawaii. The United States immediately declared war on Japan. On December 11, Germany and Italy declared war on the United States as the military conflict widened. In May 1942, the British Royal Air Force carried out a raid on the German city of Cologne with a thousand bombers, for the first time bringing war home to Germany. For the next three years, Allied air forces systematically bombed industrial plants and cities all over the Reich, reducing much of urban Germany to rubble by 1945. In late 1942 and early 1943, the Allied forces achieved a series of significant military triumphs in North Africa. The failure of French armed forces to prevent Allied occupation of Morocco and Algeria triggered a German occupation of collaborationist Vichy France on November 11, 1942. Axis military units in Africa, approximately 150,000 troops in all, surrendered in May 1943. On the eastern front, during the summer of 1942, the Germans and their Axis allies renewed their offensive in the Soviet Union, aiming to capture Stalingrad on the Volga River, as well as the city of Baku and the Caucasian oil fields. The German offensive stalled on both fronts in the late summer of 1942. In November, Soviet troops launched a counteroffensive at Stalingrad and on February 2, 1943, the German Sixth Army surrendered to the Soviets. The Germans mounted one more offensive at Kursk in July 1943, the biggest tank battle in history, but Soviet troops blunted the attack and assumed a military predominance that they would not again relinquish during the course of the war. In July 1943, the Allies landed in Sicily and in September went ashore on the Italian mainland. After the Italian Fascist Party's Grand Council deposed Italian premier Benito Mussolini (an ally of Hitler), the Italian military took over and negotiated a surrender to Anglo-American forces on September 8. German troops stationed in Italy seized control of the northern half of the peninsula, and continued to resist. Mussolini, who had been arrested by Italian military authorities, was rescued by German SS commandos in September and established (under German supervision) a neo-Fascist puppet regime in northern Italy. German troops continued to hold northern Italy until surrendering on May 2, 1945. On June 6, 1944 (D-Day), as part of a massive military operation, over 150,000 Allied soldiers landed in France, which was liberated by the end of August. On September 11, 1944, the first US troops crossed into Germany, one month after Soviet troops crossed the eastern border. In mid-December the Germans launched an unsuccessful counterattack in Belgium and northern France, known as the Battle of the Bulge. Allied air forces attacked Nazi industrial plants, such as the one at the Auschwitz camp (though the gas chambers were never targeted). The Soviets began an offensive on January 12, 1945, liberating western Poland and forcing Hungary (an Axis ally) to surrender. In mid-February 1945, the Allies bombed the German city of Dresden, killing approximately 35,000 civilians. American troops crossed the Rhine River on March 7, 1945. A final Soviet offensive on April 16, 1945, enabled Soviet forces to encircle the German capital, Berlin. As Soviet troops fought their way towards the Reich Chancellery, Hitler committed suicide on April 30, 1945. On May 7, 1945, Germany surrendered unconditionally to the Western Allies at Reims and on May 9 to the Soviets in Berlin. click above to learn about the battle of berlin

the war against japanJapanese expansion in East Asia began in 1931 with the invasion of Manchuria and continued in 1937 with a brutal attack on China. On September 27, 1940, Japan signed the Tripartite Pact with Germany and Italy, thus entering the military alliance known as the "Axis." Seeking to curb Japanese aggression and force a withdrawal of Japanese forces from Manchuria and China, the United States imposed economic sanctions on Japan. Faced with severe shortages of oil and other natural resources and driven by the ambition to displace the United States as the dominant Pacific power, Japan decided to attack the United States and British forces in Asia and seize the resources of Southeast Asia.
Japan launched a surprise attack on the United States Pacific fleet at Pearl Harbor, Hawaii, on December 7, 1941. The attack severely damaged the American fleet and prevented, at least for the short term, serious American interference with Japanese military operations. In response, the United States declared war on Japan. Following Germany's declaration of war on the United States, the United States also declared war on Germany. After the attack on Pearl Harbor, Japan achieved a long series of military successes. In December 1941, Guam and Wake Island fell to the Japanese, followed in the first half of 1942 by the Philippines, the Dutch East Indies, Hong Kong, Malaya, Singapore, and Burma. Thailand remained officially neutral. Only in mid-1942 were Australian and New Zealander forces in New Guinea and British forces in India able to halt the Japanese advance. The turning point in the Pacific war came with the American naval victory in the Battle of Midway in June 1942. The Japanese fleet sustained heavy losses and was turned back. In August 1942, American forces attacked the Japanese in the Solomon Islands, forcing a costly withdrawal of Japanese forces from the island of Guadalcanal in February 1943. Allied forces slowly gained naval and air supremacy in the Pacific, and moved methodically from island to island, conquering them and often sustaining significant casualties. The Japanese, however, successfully defended their positions on the Chinese mainland until 1945. Late in 1944, American forces liberated the Philippines and began massive air attacks on Japan. British forces recaptured Burma. In early 1945, American forces suffered heavy losses during the invasions of Iwo Jima (February) and Okinawa (April), an island of strategic importance off the coast of the Japanese home islands. Despite these casualties and suicidal Japanese air attacks, known as Kamikaze attacks, American forces conquered Okinawa in mid-June 1945. On August 6, 1945, the United States Air Force dropped an atomic bomb on the Japanese city of Hiroshima. Tens of thousands of people died in the initial explosion, and many more died later from radiation exposure. Three days later, the United States dropped a bomb on the Japanese city of Nagasaki. Approximately 120,000 civilians died as a result of the two blasts. On August 8, the Soviet Union declared war on Japan and invaded Japanese-occupied Manchuria. After Japan agreed to surrender on August 14, 1945, American forces began to occupy Japan. Japan formally surrendered to the United States, Great Britain, and the Soviet Union on September 2, 1945. above short video on pearl harbor

the war against italyThe Italian attack on British forces in Egypt was initially to coincide with Operation Sealion, the proposed-but-never-attempted German sea invasion of Britain in 1940. When it became apparent to Mussolini that Sealion was postponed indefinitely, he ordered Marshal Rodolfo Graziani to launch his 10th army, comprised of 7 divisions, into combat across the Egyptian border from Libya. Field Marshal Graziani led his numerically superior Italian force across the Libyan-Egyptian border in September 1940 against a smaller but highly mobile British enemy. The campaign was a disaster, and by December of that year the Italian forces in North Africa were on the verge of certain collapse.
Historians note that German Field Marshall Erwin Rommel arrived in Tripoli, Libya, in February 1941 and over the next month assembled an ad hoc German light infantry division with panzer and motorized infantry, to give the Italians the firepower and leadership needed to defeat the British. He assumed command of the Deutsches Afrika Korps and received assistance from the Fliegerkorps X and long-range aircraft from Sicily to fight the exhausted British. Although Rommel’s leadership ability and German firepower certainly helped the struggling Italians, the Italian military footprint also significantly changed in North Africa to counter the advancing Commonwealth forces. The Italian Ariete and Trento divisions made their debut in North Africa in February 1941 in conjunction with Rommel. The Ariete was composed of 6,949 men, 163 tanks, 36 field guns, 61 anti-tank guns and the Brescia infantry division. Rommel now had 100,000 Italians, 7,000 Italian trucks supplying munitions to the front, 1,000 Italian guns and 151 Italian aircraft under his command. After January 1941, the Italians introduced the more modern M-13/40 tanks, grouped in motorized units and not thrown together as was done in the initial offensive. They also utilized their first company of armored cars, Reparto Esplorante di Corpo d’Armata di Manovra (RECAM). By early 1942, each armored division nominally had 47 armored reconnaissance cars and each motorized division had a battalion of M13/40s. Also in 1940 the Italian forces in North Africa had 6:1 ratio of artillery to infantry battalions, while the British had a superior 8:1 The British had seventy-five 25 pounders (88mm artillery pieces) per division; Italian divisions had twenty-four 75mm and twelve 100mm guns. By the end of 1941, the Italians doubled the amount of 100/17 mm guns to 24, and added 12 88/55s or 90/53’, giving each Italian division a total of 60 guns for a ratio of 10:1. This almost doubled the amount of firepower available for Rommel, which was not available to Graziani’s forces in the initial invasion. click the button above to learn about the desert fox

operation overlordTwelve Allied nations provided fighting units that participated in the invasion, including Australia, Canada, Belgium, France, Czechoslovakia, Greece, New Zealand, the Netherlands, Norway, Poland, the United Kingdom, and the United States.
Operation Overlord was the codename for the Allied invasion of northwest Europe. The assault phase, or the establishment of a secure foothold, was known as Operation Neptune. Operation Neptune began on D-Day (June 6, 1944) and ended on June 30, when the Allies had established a firm foothold in Normandy. Operation Overlord also began on D-Day, and continued until Allied forces crossed the River Seine on August 19. The battle began months before the invasion, when Allied bombers began to pound the Normandy coast and farther south, to destroy transportation links, and disrupt the German army's build-up of their military strength. More than 300 planes dropped 13,000 bombs over Normandy in advance of the invasion. Six parachute regiments, with more than 13,000 men, also went ahead to cut railroad lines, blow up bridges, and seize landing fields. Gliders also brought in men, light artillery, jeeps, and small tanks. There has been some confusion regarding the meaning of the “D” in D-Day. The most likely explanation is offered by the U.S. Army in their published manuals. The Army began to use the codes “H-hour” and “D-Day” during World War I, to indicate the time or date of an operation’s beginning. So the “D” may simply refer to the “day” of invasion. With the invasion of Normandy, General Dwight D. Eisenhower faced a task of magnitude and hazards never before attempted. He would have to move his forces 100 miles across the English Channel and storm a heavily fortified coastline. His enemy was the weapon-and-tank-superior German army commanded by Erwin Rommel, one of the most brilliant generals of the war. Less than 15 percent of the Allied forces coming aboard the ships had ever seen combat. An invading army had not crossed the unpredictable and dangerous English Channel since 1688. Once the massive Allied force set out, there was no turning back. The Allies boasted a 5,000-vessel armada that stretched as far as the eye could see, transporting both men and vehicles across the channel to the French beaches. In addition, the Allies had 4,000 smaller landing craft and more than 11,000 aircraft. By nightfall on June 6, more than 9,000 Allied soldiers were dead or wounded, but more than 100,000 had made it ashore and secured French coastal villages. Within weeks, supplies were being unloaded at Utah and Omaha beachheads at the rate of more than 20,000 tons per day. By June 11, more than 326,000 troops, 55,000 vehicles, and 105,000 tons of supplies had been landed on the beaches. By June 30, the Allies had established a firm foothold in Normandy. Allied forces crossed the River Seine on August 19. Military intelligence was an important part of the Normandy invasion. British and American cryptographers working in London deciphered coded messages that the German believed to be unbreakable. Messages could quite often be delivered to Eisenhower within two and a half hours of the time the Germans had sent it. In addition, reconnaissance teams took infrared pictures of Omaha Beach while avoiding German patrols. There is no official casualty figure for D-Day. It is estimated that more than 425,000 Allied and German troops were killed, wounded, or went missing during the battle. That figure includes more than 209,000 Allied casualties. In addition to roughly 200,000 German troops killed or wounded, the Allies also captured 200,000 soldiers. Captured Germans were sent to American prisoner-of-war camps at the rate of 30,000 per month, from D-Day until Christmas 1944. Between 15,000 and 20,000 French civilians were killed during the battle. In the end, the invasion of Normandy succeeded in its objective by sheer force of numbers. By July 1944, some one million Allied troops, mostly American, British, and Canadian, were entrenched in Normandy. During the great invasion, the Allies assembled nearly three million men and stored 16 million tons of arms, munitions, and supplies in Britain. |
