German forces started its Tallinn Offensive on 19 August 1941, capturing Rapla on 21 August 1941. They reached Tallinn outskirts in Pirita on 24 August 1941 and Harku and Lasnamäe on 26 August 1941. Ordinary citizens were ordered to build defenses around Tallinn. Soviet forces started evacuating by sea on 24 August 1941. Of the 195 ships, that left Tallinn and Paldiski, 55 were sunk by mines near Juminda Peninsula, killing around 15,000 evacuees. Evacuating Soviet forces destroyed much of the infrastructure and industry around Tallinn. German forces captured Paldiski and Tallinn on 28 August 1941, shooting down the Soviet Flag on Tallinn Pikk Hermann Tower. Estonians replaced it with the Flag of Estonia, but it was replaced with the Flag of Germany the next day. German forces were greeted as liberators in Tallinn. It was also the first time since 1219 that Tallinn had been captured following a military engagement.
