On 9 April – one month before the end of the war in Europe – the German military commander of Königsberg, General Otto Lasch, surrendered the remnants of his forces, following the three-month-long siege by the Red Army. For this act, Lasch was condemned to death, in absentia, by Hitler. At the time of the surrender, military and civilian dead in the city were estimated at 42,000, with the Red Army claiming over 90,000 prisoners. Lasch's subterranean command bunker is preserved as a museum in today's Kaliningrad.
