The 345th Rifle Division began forming in September, 1941, as a standard Red Army rifle division, at Makhachkala on the Caspian Sea. Its first formation served exclusively in the southernmost parts of the Soviet-German front, specifically in the Caucasus and Crimea. It arrived at Sevastopol in December, and fought stubbornly in defense of the fortress-port until mid-July, 1942, when the city capitulated and the division was destroyed. In March, 1945, a new 345th was formed in the Far East, and a few months later took part in the Soviet invasion of Manchuria in August, but as it was in a reserve formation it saw little, if any, actual combat.
