Twenty-five thousand Soviet soldiers spent the summer and autumn of 1941 on a peninsula they had been given by treaty and surrounded by people who wanted them gone. Hanko, the southwestern tip of Finland, had been leased to the Soviet Union as a naval base in March 1940 — one of the harsh terms imposed on Finland after the Winter War. The Finnish civilians had been forced to evacuate. Soviet engineers built an airfield, garrisoned the islands, and dug in. When Finland joined the German invasion of the Soviet Union in June 1941, Hanko became an island in enemy territory. For six months neither side wanted to assault the place head-on, so they fought the kind of war the geography invited: artillery duels, sniper exchanges, small amphibious raids on lighthouses, and a final evacuation across mined seas that cost the Soviet Baltic Fleet three destroyers and two passenger liners crammed with troops.
