Simo Häyhä was called into action during the Winter War with his service under the 6th Company of JR 34 on the Kollaa River. The Finnish stand at Kollaa is often referred to as "The miracle of Kollaa," as the Finnish action here was most heroic. The Finnish forces in the region were under the command of Major General Uiluo Tuompo and they faced the 9th and 14th Soviet Armies. At one point the Finns at Kollaa were facing 12 divisions, some 160,000 men. The Red Army losses in this arena were staggering as the brave Finns took their toll on the communist invaders. There have been those that called the Finnish defense of this key region "fanatical", and it was in the Kollaa area were the famous battle of "Killer Hill" took place with 32 Finns battling 4,000 Soviet soldiers. These were the hunting grounds of Simo Häyhä and it should be noted that even against massive odds the Kollaa positions were still in Finnish hands at the end of the war (March 1940).
