text: The Royal Romanian Navy was involved in the evacuation of Axis forces from Crimea in 1944. The Romanian naval commander, Rear Admiral Horia Macellariu, was awarded the German Knight's Cross of the Iron Cross after Operation 60,000, the contingency plan for the evacuation of Crimea. Until King Michael's Coup, the Romanian Navy retreated behind the protection of the coastal mine barrages and anti-aircraft defences of Constanța as the Soviet Air Force began to launch heavy air attacks. On the capitulation of Romania in August 1944, the German warships were ordered to leave Romanian harbours. However, when the Soviet minesweeper T-410 Vzryv, accompanied by Amiral Murgescu, was sunk by a German submarine, the Soviet Navy accused the Royal Romanian Navy of betrayal and seized all vessels using this excuse on 5 September 1944. By this late stage of the war, only one destroyer (Regina Maria), one leader (Mărășești), two gunboats (Dumitrescu and Ghiculescu), one minelayer (Amiral Murgescu) and three motor torpedo boats were still operational. The rest of the warships were in repairs after the evacuation of Crimea and the Soviet air attacks of the preceding couple of months or had been relegated to training duties. The Soviet Navy moved all Romanian warships to Caucasian ports. They were not returned until after the war. The older vessels were received in September 1945, while the more modern ones (such as the Regele Ferdinand class) were kept by the Soviet Black Sea Fleet until the early 1950s. A number of warships were never returned.
