In August and September 1944, the 15th Division was moved to Prussia, for replenishment with new recruits. It was in training near Danzig until being ordered into battle on 22 January 1945. At that time, the division consisted of about 15,000 soldiers. It fought near Danzig in January and February, retreating to Pomerania in early March. By early April, the division was reduced to 8,000 men. About 1,000 were sent by sea to replenish the forces in the Courland Pocket, the rest were lost during the fighting. On April 11, the division was told about plans to transfer the entire division to Courland. Seeing that the war was lost and understanding that being sent to Courland would mean eventually having to surrender to the Soviets, the division decided to surrender to the Western Allies instead, disobeying German orders to the contrary, when necessary.
