The Twentieth Army Corps (Russian: 20-й армейский корпус) was a formation of the Imperial Russian Army that was first raised in 1899, and most famous for fighting on the Eastern Front in World War I, most notably during the Second Battle of the Masurian Lakes. Before World War I, the 20th Corps was stationed in the Vilna Military District with its headquarters in Riga. At the outbreak of the war, the corps consisted of two infantry divisions and a number of independent battalions and brigades. Many Lithuanians served in this unit with the 28th Division having particularly many Lithuanians, especially in the 109th and 111th Infantry Regiments.[1] Some regiments in this Corps were 80% Latvian.[2] The corps was demobilized in April 1917.[3]
