The 27th Infantry Division Savska was an infantry formation of the Royal Yugoslav Army's 4th Army during the German-led Axis invasion of the Kingdom of Yugoslavia in April 1941. Commanded by August Marić, the division was largely made up of Croat troops, many of whom saw the Germans as potential liberators from Serbian oppression. It lacked modern arms and sufficient ammunition, and like all Yugoslav infantry divisions of the time, relied on animal transport. Upon mobilisation, the division began to disintegrate due to fifth column actions, rebellion and desertion. Its chief of staff countermanded orders for the sabotage of a key bridge over the Drava river at Zákány, allowing the German 14th Panzer Division to cross. In a single day, with overwhelming air support, the panzers brushed aside the mostly Serbian remnants of the division and captured Zagreb, covering nearly 160 km (100 mi) and meeting little resistance (Yugoslav generals pictured).
