363rd Infantry Regiment Combat History

The 363rd Infantry Regiment was organized at Camp White, Oregon, on August 15, 1942, trained with the 91st Division, departed Hampton Roads on April 13, 1944, and arrived in North Africa on April 30. It landed in Italy on June 19 and entered combat on July 4 during the attack on Hill 675. Two days later it overran Monte Vase northeast of Castellina, though a German counterattack retook the position.

During the July drive to the Arno, the 363rd fought both under the 91st Division and in attachment to the 34th Division. With the 135th Infantry it entered Leghorn before daylight on July 19 after the German garrison withdrew. A battalion then fought into Marina di Pisa near the Arno mouth, and two battalions occupied the south-bank portion of Pisa on July 23 while enemy fire continued from north of the river.

In September the regiment led the 91st Division toward Il Giogo Pass and became the central American unit in the fight for Monticelli. Its battalions attacked the steep, fortified ridge under heavy mortar, machine-gun, and artillery fire. Company B's advance through Borgo and onto the western ridge opened the first important breach, and after repeated counterattacks the 3rd Battalion reached Monticelli's summit on September 17. The victory helped break the Gothic Line west of Il Giogo Pass. In October the 363rd attacked toward Loiano on the division left, cleared the Monzuno-Loiano road, climbed the Livergnano escarpment to reinforce the 361st, and cleared the eastern plateau. It later advanced toward Monte Belmonte to help the 34th Division. In April 1945 it joined the Highway 65 offensive, the Po Valley pursuit, and the drive through the Adige, Brenta, and Treviso before the surrender in Italy.
