Between 1941 and 1944, Romania held control over much of the Ukrainian Black Sea coast East of the Crimea. This was acquired during "Operation Barbarossa". The Romanian conquest of the Soviet Western Black Sea coast started in July 1941 during "Operation München" and ended in October that year, after the Siege of Odessa. In the aftermath of these actions, Romania acquired two new sectors of coastline: the Bessarabian coast and the Transnistrian Coast. The latter was lost in April 1944, but the former was successfully defended until August 1944.
