The 28 Dywizja Piechoty was a Polish Army infantry division which saw action against the invading Germans during the Invasion of Poland of World War II. The division suffered heavy casualties in battles near Łódź and the remnants retreated to Warsaw, where they surrendered. In 1921–1939, the 28th Division was part of the 1st Military District. In 1922, the 28th Light Artillery Regiment was moved from Radom to Zajezierze near Dęblin, and in April 1922, the 72nd Infantry Regiment was transferred from Warsaw to Radom.
