The corps fought a total 916 days in the war, and at different times it was in service on the
Kalinin, the
Leningrad and the
2nd Baltic Front. For 344 days, parts of the corps were engaged with
German forces, but no significant gains were made. For the next 123 days, the formation was engaging in the
Battle of Velikiye Luki where 13,000 of the 27,000 men were killed or wounded. Then, 37 days were spent in the
Battle of Narva, and the final 88 days were devoted to the
Battle of Courland. During the Battle of Narva in 1944, the artillery of the rifle corps fired on the
20th Waffen Grenadier Division of the SS (1st Estonian), consisting of Estonians fighting in the
Waffen SS. The infantry of the corps was engaged in direct battle with the Estonians on the German side in the battles of
Porkuni and Avinurme on 20 and 21 September 1944, where a detachment of the rifle corps murdered a number of wounded prisoners of war. On 22 September elements of the 7th Rifle Division, along with the 45th Estonian Tank Regiment and the 952nd SU Regiment (
SU-76s), formed the forward detachment of the corps and entered
Tallinn, for which all three units received the name of that city as a battle honor. The corps appears to have spent the last of its World War II service in the
42nd Army. ==Post-war==
