The Battle of Cape Burnas was a naval engagement between the Soviet and Romanian navies near the Burnas Lagoon in October 1942. On 1 October 1942, the Soviet M-class submarine M-118 attacked and sank the German transport ship Salzburg, which was carrying on board 2,000 Soviet prisoners of war. After attacking, the submarine was located by a German BV 138C flying boat, and the Romanian gunboats Sublocotenent Ghiculescu and Stihi Eugen were sent to the scene. The two Romanian warships attacked the Soviet submarine with depth-charges, sinking her with all hands.
