In late summer 1943, it took over the Cannes–Nice sector on the Mediterranean coast when elements of the Italian 4th Army returned home.

Sent to the rear, the 715th was rebuilt, largely from troops of the reinforced 1028th Grenadier Regiment and Shadow Division Wildflecken, which it absorbed.

The division fought in the Gothic Line battles in September and was transferred to the Adriatic sector soon after.

During this time the Italian Bersaglieri battalion "Mameli" fought under the command of the 715th Infantry Division.

In early 1945, it was sent to the 1st Panzer Army on the Eastern Front, fought in Upper Silesia and surrendered to the Soviets in the Tábor–Písek area of Czechoslovakia on 2 May.
