General Wladyslaw Sikorski was the Head of the wartime Polish Government and Polish Commander-in-Chief, 1939-1943\. Sikorski rose to prominence in Poland between 1910 and 1918 as part of the movement towards Polish independence, achieved in 1918\.

In 1920 Sikorski was largely responsible for the defeat of the Red Army. In 1926 he fell from favour following a military coup. During this fallow period, 1926-1939, Sikorski travelled, mainly in France. He also wrote influential military-science treatises. In September 1939 Germany and the Soviet Union invaded and annexed Poland. Sikorski, his military offices refused by the Polish Government, fled to Romania.
