4th Infantry Division (Russian Empire)

The 4th Infantry Division (4-я пехотная дивизия, 4-ya Pekhotnaya Diviziya) was an infantry formation of the Russian Imperial Army that existed in various formations from 1806 until the end of World War I and the Russian Revolution. When the war broke out in 1914 it was based in Łomża. In June 1917, it was designated as the 4th Infantry Shock Division (4-я пехотная ударная дивизия) upon being reformed as a shock troop unit and the following month it became known as the 4th Infantry Shock Division of Death (4-я пехотная ударная дивизия смерти).
