On April 23, 1945, US troops in Italy cross river Po. From the article:
"In the II Corps zone, Bologna fell to the U.S. 34th Infantry Division on the morning of 21 April, but General Truscott left the city to his Italian troops and sent the 34th west toward Modena. By reinforcing the IV Corps' left flank, he hoped to isolate enemy divisions still retreating from the northern Apennines and to deny them Po River crossings west of the 1st Armored Division. Attaching the 34th Division to the IV Corps, he instructed Crittenberger to put it astride Highway 9 between the 1st Armored Division and the Brazilian Expeditionary Force. Subsequently, the 34th Division reached Modena on 23 April and continued its attack northwest along Highway 9 toward Reggio, ten miles farther. Meanwhile, the 6th South African Armored Division led the II Corps' advance to the Panaro River and on to the Po, with the U.S. 88th Infantry Division mopping up the rear areas of Axis stragglers. On their right, the 91st Division skirted the western outskirts of Bologna, captured the airport, and continued north, rapidly approaching the Panaro.
By dawn on 22 April the entire Fifth Army was well into the Po Valley. On the right flank, Axis forces attempted in vain to prevent the juncture of the Fifth and Eighth Armies, desperately trying to buy time for small detachments of their comrades to escape. But the Allied onslaught, now moving at full speed, quickly swept aside the hasty defenses erected by the 1st and 4th Parachute Divisions, overwhelming and annihilating numerous Axis rear-guard detachments in the process.
In the west, the 10th Mountain Division's spearhead reached the Po River at San Benedetto, thirty miles north of Ponte Samoggia, on

Prisoners were captured by the tens of thousands in the Po Valley and marched to the rear, often unguarded or guarded by only one or two men.

the evening of 22 April. By midnight, the rest of the division had arrived' and river-crossing equipment followed. Masses of destroyed enemy materiel littered the south bank of the Po, showing the devastating effects of Allied air power. Not one bridge remained standing. As the 10th Mountain Division waited to cross, the 1st Armored Division skirted Modena over a captured Panaro River bridge four miles north of Highway 9, then moved west, reaching a southwestern loop of the Po on 23 April. The units' armored vehicles then spread out along several miles of the river's southern bank to block crossings by any remaining enemy soldiers bypassed in the headlong race for the river. The rapid American advance along the forty-mile-wide front had left many pockets of Axis soldiers, and special task forces were now created to mop up rear areas as the main Allied units pressed farther northward. Ultimately, over 100,000 Axis troops were forced to surrender in the areas south of the river.

Although the majority of the Po River bridges were destroyed, the U.S. 85th Infantry Division, like other fast-moving Fifth Army units, had been able to take many spans south of the Po intact, such as the Panaro River bridge at Camposanto, eleven miles north of Ponte Samoggia. Early on 22 April, fearing efforts of enemy rear-guard units to destroy the span, a sergeant from the division's 310th Engineer Battalion quickly plunged into the river, cut the demolition wires under enemy fire, and saved the structure from destruction. Once across, the 310th repelled an enemy attempt to retake the bridge and to hold the town. As one regiment cleared Camposanto and secured the span, another swung to the left, crossed the bridge seven miles south at Bomporto, and quickly covered the intervening twenty-four miles of territory, arriving at the Po River just before noon on 23 April 1945. The division then cleared the south bank, capturing hundreds of prisoners and much equipment in the process. Later in the day a westward shift of corps boundaries caused the 85th Division to relinquish some of its territory to the 88th Division, which had only left the Panaro River early that morning. The 85th then prepared to cross the Po River in force the next day.
By 24 April the entire Fifth Army front had reached the Po. In the west, IV Corps units advanced west, northwest, and north, pushing forward bridging equipment for an offensive across the river. In the 10th Division area, fifty M-2 assault boats enabled the unit to begin ferrying troops across at noon. Air bursts from German artillery caused some casualties, but enemy actions failed to significantly delay the crossings here or elsewhere. Once on the far bank, the 10th Mountain quickly secured its bridgehead. By 1800 hours two regiments were on the far bank, with the division's third regiment crossing during the night."
