Polish Armed Forces in the WestThe Polish Armed Forces in the West (Polskie Siły Zbrojne na Zachodzie) refers to the Polish military formations formed to fight alongside the Western Allies against Nazi Germany and its allies during World War II. Polish forces were also raised within Soviet territories; these were the Polish Armed Forces in the East. The formations, loyal to the Polish government-in-exile, were first formed in France and its Middle East territories following the defeat and occupation of Poland by Germany and the Soviet Union in September 1939.
Military history of Poland during World War IIIn World War Two, the Polish armed forces were the fourth largest Allied forces in Europe, after those of the Soviet Union, United States, and Britain. Poles made substantial contributions to the Allied effort throughout the war, fighting on land, sea, and in the air. Polish forces in the east, fighting alongside the Red army and under Soviet high command, took part in the Soviet offensives across Belarus and Ukraine into Poland and across the Vistula and Oder Rivers to the Battle of Berlin.
Allies of World War IIThe Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during the Second World War (1939–1945) to oppose the Axis powers, led by Nazi Germany, the Empire of Japan, and the Kingdom of Italy. Its principal members by the end of 1941 were the United Kingdom, United States, Soviet Union, and China. Membership in the Allies varied during the course of the war. When the conflict broke out on 1 September 1939, the Allied coalition consisted of the United Kingdom, France, and Poland, as well as their respective dependencies, such as British India.
Phoney WarThe Phoney War (Drôle de guerre; Sitzkrieg) was an eight-month period at the start of World War II during which there was only one limited military land operation on the Western Front, when French troops invaded Germany's Saar district. Nazi Germany carried out the invasion of Poland on 1 September 1939. The Phoney period began with the declaration of war by the United Kingdom and France against Nazi Germany on 3 September 1939, after which little actual warfare occurred, and ended with the German invasion of France and the Low Countries on 10 May 1940.
