The other German group was General von Erdmannsdorff's LXXXXI Corps of Army Group E in northern Yugoslavia. LXXXXI Corps had concentrated near Donji Miholjac and Valpovo. Across the Drava River at Donji Miholjac, the IV Corps of the Bulgarian Army defended the routes leading to Pécs and Mohács. Northeast of Valpovo and across the Drava, General Nađ's 3rd Army of Josip Broz Tito's Yugoslav National Liberation Army defended the routes leading to northeast Yugoslavia. Named "Forest Devil" (), the LXXXXI Corps' operation had as its primary objective the town of Mohács.
