During World War II, Operation Margarethe II was the name for a planned invasion of Romania by German forces in conjunction with those of Hungary and Bulgaria if the Romanian government decided to surrender to the Allies and switch sides.[1][2][3][4] Although initially abandoned within a few weeks at the start of 1944,[5] after King Michael's coup on 23 August 1944 and Antonescu's arrest, Hitler ordered the operation to commence. Led by Luftwaffe General Alfred Gerstenberg, then by General Reiner Stahel, the operation ultimately failed to occupy Bucharest and overthrow Michael and the new government.[6]
