The Battle of Rimini took place between 13 and 21 September 1944 during Operation Olive, the main Allied offensive on the Gothic Line in August and September 1944, part of the Italian Campaign in the Second World War. Rimini, a town on the Adriatic coast of Italy, anchored the Rimini Line, a German defensive line which was the third such line forming the Gothic Line defences. Rimini, which had been hit previously by 373 air raids, had 1,470,000 rounds fired against it by allied land forces; by the end of the battle, only 2% of all buildings in the city were still undamaged.
