SOUTH AFRICAN ARMOR waiting along Highway 64 for a U. S. infantry division to pass on its way to the Po Valley, 20 April. On this date the troops in the U. S. zone broke through the mountains into the Po Valley just west of Bologna. The two highways in this area, 64 and 65, became congested with troops and vehicles in pursuit of the fleeing enemy. (Sherman medium tanks.)] [Illustration: ITALY U. S. ARMY MOTION-PICTURE CAMERAMAN photographing the first tank of the South African armored force to cross the Reno River southwest of Bologna, 20 April. The practice of infantrymen riding on tanks while advancing was included in training for armored units in the United States early in 1944. (Sherman M4A3 tank with British 17-pounder; camera: PH-330 (Sig C), Eyemo, Bell, and Howell, 35-mm., three lenses mounted in turret.)] [Illustration: ITALY WEARY U. S. TROOPS IN BOLOGNA on the morning of 21 April. The city, entered from the south by U. S. forces and from the east by Poles of the Eighth Army, fell that day. Pressing forward the troops pursued the fleeing Germans.] [Illustration: ITALY ITALIAN PARTISANS WATCHING FOR SNIPERS. During the winter of 1944–45 Allied officers, arms, and ammunition were dropped behind the enemy lines to assist partisans in the Po Valley. Although partisans, armed with equipment obtained from Italian arsenals or seized from the Germans, first appeared north of Rome, it was not until the Allies reached Bologna that they met the efficiently organized groups from the Po Valley. As troops entered the city, where the Germans were numerous, the partisans struck, seizing government agencies and public utilities.] [Illustration: ITALY THE PANARO RIVER BRIDGES near Bomporto. After the breakout into the Po Valley, the next objective was the Po River. The area south of this river is broken by small streams and numerous canals. Most of the bridges had been destroyed by the Allied air forces during the winter. Later air reconnaissance found these undamaged bridges at Bomporto. A task force, sent to secure them, passed through the fleeing and disorganized enemy. So sudden was its appearance that, by 1600 on 21 April, it captured the bridges before the Germans could detonate previously laid demolition charges.] [Illustration: ITALY TREADWAY BRIDGE ACROSS THE PO RIVER at San Benedetto. Opened on the afternoon of 25 April, it was the first bridge across the river. The infantry had started to cross in this area on the morning of the 23d in assault boats under heavy machine gun, mortar, and rifle fire as well as fire from enemy antiaircraft guns lowered to fire airbursts on a flat trajectory. Casualties were high, but by 1745 a bridgehead of 2,000 square yards had been established on the north bank of the Po. The bridge above is 915 feet long. (Floating treadway bridge M2, class 18.)]
