East Pomeranian Offensive

East Pomeranian Offensive. The East Pomeranian Offensive was a major military operation conducted in the final months of World War II on the Eastern Front. Launched by the Red Army and the Polish People's Army against the Wehrmacht, it aimed to clear the Pomerania region of German forces and secure the flanks for the final assault on Berlin. The operation resulted in the Soviet capture of key cities like Danzig and Kolberg and the virtual destruction of Army Group Vistula.

Background

Following the massive success of the Vistula–Oder Offensive in January 1945, Soviet forces under Georgy Zhukov's 1st Belorussian Front had advanced rapidly to the Oder River, establishing bridgeheads near Küstrin. However, a large German force, the newly formed Army Group Vistula under Heinrich Himmler, remained intact in Pomerania, posing a significant threat to the northern flank of the Soviet advance toward the German capital. The Stavka, the Soviet high command, recognized the danger of launching the Battle of Berlin with this enemy grouping undefeated. Concurrently, the Western Allies were advancing from the west, having crossed the Rhine, increasing pressure on Adolf Hitler's regime from all sides.

Planning and preparation

The Soviet plan, devised by the Stavka and coordinated by Aleksandr Vasilevsky, involved a pincer movement by two major fronts. The primary strike force was Konstantin Rokossovsky's 2nd Belorussian Front, which had just completed the East Prussian Offensive. It was to attack westward from the Vistula Lagoon area. Simultaneously, the right wing of Zhukov's 1st Belorussian Front would strike northward from the Arnswalde region. Their objective was to converge, split, and annihilate the German forces in Pomerania, particularly the Third Panzer Army and Second Army. The 1st Polish Army, under General Karol Świerczewski, was integrated into the Soviet order of battle for the operation.

The offensive

The offensive commenced on 24 February 1945 with a powerful artillery barrage from the 2nd Belorussian Front. Rokossovsky's forces broke through German defenses near Schlochau and advanced rapidly toward Köslin, reaching the Baltic Sea near there by 1 March, effectively cutting off German forces in eastern Pomerania. To the south, Zhukov's forces attacked on 1 March, pushing toward Dramburg and Neustettin. Fierce fighting ensued around Danzig and Gdynia, where German forces, including the XLVII Panzer Corps, mounted a desperate defense. Key battles included the siege of the fortress city of Kolberg, defended by German and Volkssturm units, which fell to Polish troops on 18 March. By late March, Soviet and Polish forces had captured Danzig and crushed organized resistance, with mopping-up operations continuing into early April.

Aftermath

The offensive was a decisive Soviet-Polish victory, eliminating the German threat to the right flank of the main Soviet forces on the Oder River. It resulted in the complete liberation of Pomerania and the capture of vital Baltic Sea ports, further strangling Nazi Germany's remaining naval capabilities. The destruction of Army Group Vistula cost Germany over 250,000 casualties and freed nearly a million Soviet troops for the impending Battle of Berlin. The operation also had significant political consequences, solidifying Polish administration over the region, which was later incorporated into post-war Poland following the Potsdam Conference.
