Polish armed forces in the West

The Polish Armed Forces in the West refers to the Polish military formations formed to fight alongside the Western Allies against Nazi Germany and its allies during World War II. (Other Polish forces were raised within Soviet territories; 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. After the fall of France, in June 1940, the formations were recreated in the United Kingdom. Making a large contribution to the war effort, the Polish Armed Forces in the West was composed of army, air and naval forces. The Poles soon became shock troops in Allied service, most notably in the Battle of Monte Cassino, during the Italian Campaign, where the Polish flag was raised on the ruined abbey on May 18, 1944. The Polish Armed Forces in the West were finally disbanded, after the war, in 1947, with many former servicemen choosing to remain in exile rather than to return to communist-controlled Poland.

After Poland's defeat in September-October 1939, the Polish government-in-exile quickly organized in France a new fighting force originally of about 80,000 men. Their units were subordinate to the French Army. In early 1940 a Polish Independent Highland Brigade took part in the Battles of Narvik in Norway. A Polish Independent Carpathian Brigade was formed in the French Mandate of Syria, to which many Polish troops had escaped from Poland. The Polish Air Force in France comprised 86 aircraft in four squadrons, one and a half of the squadrons being fully operational while the rest were in various stages of training. Two Polish divisions (First Grenadier Division, and Second Infantry Fusiliers Division) took part in the defence of France, while a Polish motorized brigade and two infantry divisions were being formed.
