Battle of Vuosalmi
The Battle of Vuosalmi (also known as the Battle of Äyräpää-Vuosalmi) – the main bulk of it – lasted from July 4 to July 17, 1944. It was fought during the Continuation War (1941–1944), a part of World War II, between Finland and the Soviet Union. Background. After the Soviets saw that they had failed in the Battle of Tali-Ihantala against the Finnish defenders in the late June and early July 1944, they tried to break the Finnish positions in Vuosalmi (now Druzhnoye) and encircle the southern part of the Finnish forces in the Karelian Isthmus. Soviet  forces of the 23rd Army in the region had made unsuccessful low-scale attacks against the Finnish defenses for nearly two weeks at Äyräpää region. Lack of success from the 23rd Army's performance lead to change of command on July 3. Order of battle. Finnish. Finnish defenses on the Vuosalmi consisted initially with only the 2nd Division (Martola, later Blick). But this was later reinforced with parts of the Armored Division (Lagus), 57th Infantry Regiment and 25th Separate Battalion of 15th Infantry Division and 4th Battalion of 19th Brigade (IV/19.Pr) after the battles in the Tali-Ihantala region started  to slow down. Total 21 artillery battalions were supporting infantry during critical last stage of the battle. Per infantry battalion there were more artillery support in Vuosalmi than in Tali-Ihantala. Total forces first ~20,000 growing to ~32,000 in mid july. Average personal strength of infantry division around 13,300 men, while 6,700-7,000 of infantry brigade, 3,620 of infantry regiment and 1,022 of infantry battalion. 21 field artillery battalions (average 520-560 men each). Soviet. Soviet Leningrad Front's 23rd Army (Svetsov) was assigned with the task of making a crossing and a breakthrough at Vuosalmi. For this task 23rd  Army assigned first the 98th Rifle Corps and later switched it to the 115th Rifle Corps. Total: 8 infantry divisions, 80-90 tanks or assault/self-propelled guns and around 600 field artillery pieces or heavy mortars. Average personal strength of rifle divisions was around 6,600-6,700 men. The battle. The Finnish positions were very unfavorably located in the ridge of Äyräpää, with the wide River Vuoksi behind. Though the position was very unfavorable, the Äyräpää ridge dominated the lower lands on the northern shore requiring the defensive lines to be placed on the ridge. The Red Army 98th Corps  started heavier attacks on July 4 and heavy battles raged for control of the ridge until July 9 when Finns finally withdrew to the northern shore. The Soviet 115th Corps then continued the attack and crossed the Vuosalmi on July 9. During that day both Soviet and Finnish forces had highest numbers of artillery and mortar rounds fired: 30,000 (Soviet forces) and 18,800 (Finnish, 13,500 of it field artillery rounds). The Soviet 115th Corps reinforced the bridgehead and had all its three divisions in the bridgehead on July 11. The Finnish forces also received reinforcements in the form of the  depleted Finnish Armored Division directly from Ihantala and on July 11 both sides were attempting to attack simultaneously. Attempts on both sides were halted when they ran into attacking enemy formations. Though the Soviets now had access to the fields on the northern side, which were advantageous to the Soviet armor, the Finns were able to stop all further Soviet advances. The following Finnish counterattacks in Vuosalmi at this point amounted to not much success either, and thus both sides were on defensive here in mid-July, 1944. The Finnish field artillery fired altogether over 122,000 rounds of ordnance in  Äyräpää and Vuosalmi, from June 20 to July 17, 1944 – the same amount as in the Battle of Tali-Ihantala, which was fought during exactly the same time period in a nearby vicinity, on the relatively narrow Karelian Isthmus of Finland. Mortar units fired 85,000 rounds. When comparing 8 days period of most intensive fighting much more artillery rounds were fired in Vuosalmi (74,000) than in Tali-Ihantala (56,000). During that 8 days period in Vuosalmi Finnish mortar units fired also 52,000 rounds. Aftermath. The commander of the Soviet Leningrad Front, Marshal Leonid Govorov criticized heavily the 23rd Army, 98th  Corps and 115th Corps commanders when the offensive in Vuosalmi had not yielded any concrete results despite of the intolerably heavy casualties.
