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. When the Polish commander of II Corps, General Władysław Anders, asked for his unit to be withdrawn from the front line, Winston Churchill told him "you [the Poles] are no longer needed" but the American and British front line commanders—Generals Richard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. So they fighted together the Allies in the Battle of Bologna.
