The East Prussian Offensive was a strategic offensive by the Red Army against the Germanmarker Wehrmacht on the Eastern Front . It lasted from 13 January 1945 to 25 April 1945, though some German units did not surrender until 9 May. The Battle of Königsberg was a major part of the offensive, which ended with a total victory for the Red Army.

The East Prussian Offensive is known to German historians as the Second East Prussian Offensive. The First East Prussian Offensive (also known as the Gumbinnen Operation), took place from 16-27 October 1944, and was carried out by the 3rd Belorussian Front under General I.D. Chernyakhovsky as part of the Memel Offensive of the 1st Baltic Front. The Soviet forces took heavy casualties while penetrating 30-60km into East Prussia and Poland, and the offensive was postponed until greater reserves could be gathered.

The East Prussian Offensive

The main thrust of the offensive was to be conducted by the 3rd Belorussian Front under Chernyakhovsky. His forces were tasked with driving westwards towards Königsberg, against the defensive positions of Third Panzer Army and Fourth Army, the northern armies of General Georg-Hans Reinhardt's Army Group Centre.

From the north, on Chernyakhovksy's right flank, General Hovhannes Bagramyan's 1st Baltic Front would attack the positions of Third Panzer Army on the Nemanmarker, as well as crushing its small bridgehead at Memel. Chernyakhovsky's left flank would be supported by the 2nd Belorussian Front of Marshal Konstantin Rokossovsky, which was initially ordered to push north-west to the Vistula, through the lines of the German Second Army, thereby sealing off the whole of East Prussia.

Opening of the offensive

The Soviet offensive began on 13 January with a heavy preparatory bombardment. The Red Army made steady progress, though at the cost of very high casualties, the defenders having the advantage of substantial fortifications in the Insterburgmarker Gap east of Königsberg, and around Heilsbergmarker. Over the next few days the Third Panzer Army of General Erhard Raus was largely destroyed or withdrew into Königsberg, while General Friedrich Hossbach's Fourth Army began to find itself outflanked.

Rokossovsky attacked across the Narew on 14 January; on 20 January he received orders to swing the axis of his advance northwards towards Elbing. This sudden change of direction caught Reinhardt and Hossbach by surprise; on Rokossovsky's right flank, the 3rd Guards Cavalry Corps captured the major town of Allensteinmarker on 22 January, threatening the rear of Hossbach's formation. By 24 January, Rokossovsky's leading tank units had reached the shore of the Vistula Lagoonmarker, severing land communications with the rest of German armed forces for the entire Fourth Army along with several divisions of Second Army which were now trapped in a pocket centred on East Prussia. On the same day, Hossbach began to pull his units back from the fortified town of Lotzenmarker - a centre of the East Prussian defence system - and through a series of forced marches attempted to break out westwards.

In the meantime, Chernyakhovsky had succeeded in rolling up the defences from the East, pushing the remnants of Third Panzer Army into Königsberg and Samlandmarker. On 28 January, Bagramyan's forces captured Memel; the remnants of the three divisions defending the town were evacuated and redeployed in Samland to reinforce the defence there.

The Siege of Königsberg and the Heiligenbeil pocket

With the remnants of Army Group Centre effectively contained, Soviet forces could concentrate on reducing the German forces in Pomerania and eliminating any possible threat to the northern flank of their eventual advance on Berlinmarker. Reinhardt and Hossbach, who had attempted to break out of East Prussia and save their troops, were relieved of command, and the Army Group (redesignated Army Group North) was placed under the command of General Lothar Rendulic. Reinhardt gave up his command with the words "There is nothing more to say". Raus and the staff of the destroyed Third Panzer Army were assigned to a new formation.The defending forces, in the meantime, were besieged in three pockets by Chernyakhovsky's armies:

Even after this time German forces continued to resist on the Frische Nehrungmarker, the long sandbar enclosing the Vistula Lagoonmarker, until the end of the war.
