East Pomeranian Offensive The East Pomeranian Offensive was a major Red Army campaign on the Eastern Front (World War II) conducted from January to April 1945 that cleared Pomerania of Wehrmacht forces and secured the northern flank for the Berlin Strategic Offensive Operation. The operation involved large formations from the 1st Belorussian Front, 2nd Belorussian Front, and allied Polish and Czechoslovak forces and confronted elements of Army Group Vistula and local Volkssturm units. The offensive shaped postwar territorial arrangements and influenced the Yalta Conference settlement by accelerating Soviet control of the Baltic coast and parts of northeastern Germany.

Background

By late 1944 and early 1945 the Red Army had driven across the Vistula–Oder Offensive corridors, leaving German forces entrenched in Pomerania and along the Baltic Sea coast. Strategic concerns from Joseph Stalin and Soviet high command leaders such as Georgy Zhukov and Ivan Konev prioritized securing supply lines and flanks before a final assault on Berlin. German defenses under commanders linked to Heeresgruppe Weichsel and Army Group Vistula were reinforced by directives from Heinrich Himmler and staff officers who sought to hold coastal ports like Gdynia and Swinoujscie for evacuation and naval operations tied to the Kriegsmarine. Allied considerations, involving representatives from Winston Churchill and Franklin D. Roosevelt at wartime conferences, were influenced by Soviet operational tempo and the progress of the Vistula–Oder Offensive.

Prelude and strategic objectives

Soviet planners aimed to eliminate German pockets in Pomerania to prevent counterattacks into the exposed flank of 1st Belorussian Front during preparations for the Battle of Berlin. Objectives included capturing major transport hubs such as Stettin (now Szczecin), securing the mouths of the Oder River, and neutralizing German access to Baltic ports used for resupply or evacuation by the Kriegsmarine. High command coordination involved leaders from Red Army fronts and allied formations including the Polish People's Army and elements of the Czechoslovak Army in exile. Political aims intersected with military ones: establishing Soviet control over Pomerania also strengthened negotiating positions at forums like the Potsdam Conference and influenced postwar borders discussed among Big Three representatives.

Order of battle

Soviet and allied forces comprised multiple Fronts and armies drawn from veteran formations of the Red Army and allied contingents. Principal Soviet participants included the 1st Belorussian Front under Georgy Zhukov and the 2nd Belorussian Front under Konstantin Rokossovsky and Ivan Konev, with corps-level units fielding combined-arms armies, tank armies, artillery, and air support from the Soviet Air Forces. Polish units under commanders connected to the Polish People's Army and Czechoslovak detachments supported operations. Opposing forces included elements of Army Group Vistula, remnants of Wehrmacht infantry and panzer divisions, coastal defense units, and auxiliary formations such as the Volkssturm and naval detachments from the Kriegsmarine. Command relationships reflected directives issued by OKW leadership including Wilhelm Keitel and strategic adjustments ordered by field commanders.

Course of the offensive

Operations began in January 1945 with coordinated offensives along multiple axes aimed at isolating and encircling German groupings in Pomerania. Soviet breakthroughs exploited weaknesses in German lines left after the Vistula–Oder Offensive, forcing withdrawals, counterattacks, and localized encirclements near towns like Koszalin and Kolberg (now Kołobrzeg). Intense urban and coastal fighting saw sieges of fortified ports, amphibious operations, and airborne support with heavy involvement from Soviet Air Forces and artillery concentrations drawn from corps and army assets. German attempts to stabilize positions were hampered by shortages of reserves, fuel, and coordinated command, with some units conducting fighting retreats toward Stettin and Danzig (now Gdańsk), while others were cut off and annihilated or evacuated by sea. The offensive progressed through phases of encirclement, reduction of pockets, and mopping-up operations, culminating with Soviet control of the Baltic littoral and major transport nodes by spring 1945.

Aftermath and consequences

The offensive secured the northern flank for the subsequent Battle of Berlin and denied the Wehrmacht access to crucial Baltic ports, facilitating Soviet domination of the southern Baltic and influencing postwar occupation zones decided at the Potsdam Conference. Territorial adjustments and population transfers later involved authorities from the Polish Committee of National Liberation and Soviet military administrations, contributing to demographic shifts across Pomerania and neighboring regions. The destruction of German formations weakened Army Group Vistula and contributed to the collapse of organized German resistance in northeast Germany, while further entrenching Soviet military and political influence in Central and Eastern Europe, affecting negotiations among representatives of United States, United Kingdom, and Soviet Union leadership.

Casualties and losses

Casualty figures remain contested among historians and vary between sources from Soviet Union, Germany, and postwar archival research. German losses included tens of thousands of killed, wounded, and captured personnel from Wehrmacht divisions and supporting formations, as well as material losses of armored vehicles, artillery, and naval assets. Soviet and allied casualties also numbered in the tens of thousands across participating Red Army fronts and allied Polish and Czechoslovak units, compounded by heavy losses in urban assaults and siege operations. Civilian casualties and displacement in Pomerania were substantial, contributing to large-scale refugee movements and later population transfers enforced by postwar authorities, with long-term demographic and cultural consequences for the region.
