13th Kresy Infantry Division (Polish: 13 Kresowa Dywizja Piechoty) was a unit of the Polish Army in the interbellum period. Its origins go back to the World War I, when in June 1918 the 1st Division Division of Polish Rifles (1 Dywizja Strzelców Polskich) was formed in the French town of Villeres-Marmery. On July 8, 1918, the Division consisted of 227 officers and 10.000 soldiers, and it had been planned to be used in French attack on the German town of Saarbrücken, in the fall of 1918. Armistice, signed in November 1918, changed those plans.
