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.[7][8][9] 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Soviets in its entirety.[7] When the Polish commander of II Corps, General Władysław Anders, asked for his unit to be withdrawn from the front line, Winston Churchill told him "you [the Poles] are no longer needed" but the American and British front line commanders—Generals Richard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.[7][9]

The offensive on Bologna started on 9 April at 4:00 am local time, with a major air and artillery bombardment of 400 guns firing on German positions, followed by an advance of ground forces the same evening.[2][11] Friendly fire caused casualties as American bombers killed 38 advancing Polish troops on that day.[12][13] The American and British units engaged the German flanks, while the Polish units broke through to the city.[2] On 10 April, Polish forces pushed the Germans away from the Senio River.[2] From 12 to 14 April Polish forces fought the Germans at the Santerno River and captured Imola.[2] From 15 to 16 April, the Poles fought at the Sillaro River and the Medicina Canal.[2] On 17 April, the commander of the Eighth Army ordered the Polish forces to continue their push towards Bologna from the east. The city was to be taken initially by the American troops of the Fifth Army advancing from the south.[2][14]
On 21 April the 3rd Carpathian Rifle Brigade of the Polish 3rd Carpathian Infantry Division entered the city, where only isolated German units were still fighting.[2] (Another source attributes the entrance to the Polish 5th Kresowa Division).[12] By 6:15 am the Poles had secured the city, displaying Polish flags from the city hall and the Torre Asinelli tower, the highest tower in the city.[14] The local Italian population welcomed the Poles as their liberators.[2][14] At 8:00 am, American (South African[15]) tanks arrived in the city, followed by Italian partisans and the "Friuli" division of the Italian Co-belligerent Army.[14]
Aftermath
The Battle of Bologna was the last battle of the Polish II Corps, which was taken out of the front line on 22 April.[2][14] American and British troops completed their encirclement of the Germans forces north of the Reno River, the 8th Indian Division crossed the Po River and the German forces in Italy capitulated on 29 April.[2][14] The Polish II Corps, commanded by General Zygmunt Bohusz-Szyszko, suffered 234 dead and 1,228 wounded out of 55,780 front line personnel.[7][14]
German divisions were left in disarray, and as the end of the war neared, many splintered into small groups in order to retreat across the Po and try to reach the passes into Germany. The 65th Infantry Division lost its commander, Generalmajor Hellmuth Pfeifer in the last days of the war as he tried to make his way north with the remnants of divisional headquarters.[16]
