 During the World War II German-led Axis invasion of Yugoslavia in April 1941, Morava was the flagship of the 2nd Mine Barrage Division, and operated on the Tisza river. She fought off attacks by the Luftwaffe, and shot down one enemy aircraft, but was forced to withdraw to Belgrade. Due to high river levels and low bridges, navigating monitors was difficult, and she was scuttled by her crew on 11 April. Some of her crew tried to escape cross-country towards the southern Adriatic coast, but most surrendered on 14 April. The remainder made their way to the Bay of Kotor, which was captured by the Italian XVII Corps on 17 April. She was later raised by the navy of the Axis puppet state the Independent State of Croatia and continued in service as Bosna until June 1944, when she struck a mine and sank.
