This crossing of the Volturno opened the second phase of the Allied campaign in Italy. Five weeks earlier the Fifth Army had landed on the hostile beaches of the Gulf of Salerno. Now it was attacking a well-defended river line.Along the Volturno the Germans had entrenched themselves in the first good defensive position north of Naples. Under pressure from the Fifth Army, commanded by Lt. Gen. Mark W. Clark, their rearguards had relinquished the great port of Naples with its surrounding airfields, providing us with the base necessary for large-scale operations west of the rugged Apennine mountain range, backbone of the Italian peninsula. East of the Apennines the British Eighth Army, under General Sir Bernard L. Montgomery, had reached the mouth of the Biferno River during the first week of Oct.. The Eighth and Fifth Armies now held a line across the peninsula running south from Torre Petacciato on the Adriatic Sea for some sixty-five miles, then west to a point on the Tyrrhenian Sea just south of the Volturno. Along this line of rivers and mountains the Germans clearly intended to make a stubborn stand, hoping to delay, perhaps to stop, our northward advance.Within six weeks, Fifth Army troops had driven the Germans back to the Volturno, had executed a difficult river crossing in the face of a well-entrenched enemy, had gone on to cross the river a second and a third time, and had forced Kesselring’s hard-pressed army back into the chain of mountains which formed his next strong defensive position. Whether fighting across rivers, through valleys, or up steep mountain slopes, our men had everywhere proved their ability to defeat Hitler’s vaunted master race.
