 Initially it was thought that many thousands had drowned, but when the tunnels were pumped out in October 1945 it was found that most of the bodies were of people who had died of their wounds, not from drowning.In any event, the Soviets continued their advance with three T-34s, making it as far as Wilhelmstrasse "U-Bahn" station before being ambushed and destroyed by the Frenchmen of the "Nordland" Division.During 27 and 28 April, most of the formations of Konev's 1st Ukrainian Front that were engaged in the Battle in Berlin were ordered to disengage and proceed south to take part in the Prague Offensive (the last great offensive of the European theatre).
