The morale of the Polish forces was weakened by the outcome of the Yalta Conference which ended on 11 February , where the British and Americans , without consultation with the Poles , had decided to give a major part of the 1921 – 1939 Polish territories to the Soviet Union . One of the three Polish divisions , the Polish 5th Kresowa Infantry Division , was named after the Kresy region , which was now given to the Soviets in its entirety . When the Polish commander of II Corps , General Władysław Anders , asked for his unit to be withdrawn from the front line , Winston Churchill told him " you the Poles are no longer needed " but the American and British front line commanders — Generals Richard McCreery , Mark Wayne Clark and Field Marshal Harold Alexander — requested Anders that the Polish units remain in their positions , as they had no troops to replace them . Anders eventually decided to keep the Polish units engaged
