Władysław Eugeniusz Sikorski was a Polish military and political leader.

The Polish Legions was a name of the Polish military force established in August 1914 in Galicia soon after World War I erupted between the opposing alliances of the Triple Entente on one side and the Central Powers on the other side, comprising the German Empire and Austria-Hungary. The Legions became "a founding myth for the creation of modern Poland" in spite of their considerably short existence; they were replaced by the Polish Auxiliary Corps formation on 20 September 1916, merged with Polish II Corps in Russia on 19 February 1918 for the Battle of Rarańcza against Austria-Hungary, and disbanded following the military defeat at the Battle of Kaniów in May 1918, against Imperial Germany. General Haller escaped to France to form the Polish army in the West against the anti-Polish German-Bolshevik treaty.
