Battle of Königsberg

LOADING MAP TELEMETRY…

Overview

The Battle of Königsberg, also known as the Königsberg offensive, was one of the last operations of the East Prussian offensive during World War II. In four days of urban warfare, Soviet forces of the 1st Baltic Front and the 3rd Belorussian Front captured the city of Königsberg, present day Kaliningrad, Russia. The siege started in late January 1945 when the Soviets initially surrounded the city. Heavy fighting took place for control of overland connection between Königsberg and the port of Pillau, but by March 1945 Königsberg was hundreds of kilometres behind the main front line in the eastern front. The battle ended when the German garrison surrendered to the Soviets on 9 April after a three-day assault made their position untenable.

Significance

The Battle of Königsberg was one of the final operations of the East Prussian offensive, concluding with the Soviet capture of a heavily fortified German city in four days of urban warfare. The city had been effectively isolated since late January 1945, when Soviet forces first surrounded it, and by March 1945 it lay hundreds of kilometres behind the main front line. Control of the overland corridor to the port of Pillau was contested during the siege, but the garrison's position became untenable after a three-day assault. The German commander's surrender on 9 April eliminated a significant pocket of resistance and secured Soviet control over East Prussia, removing one of the last organized German defensive positions in the region as the war in Europe approached its end. The city itself subsequently became Kaliningrad, incorporated into the Soviet Union.
