Italian Mare Nostrum
There were a series of surface actions (e.g., Battle of Cape Matapan, Battle of Punta Stilo, Battle of Cape Teulada, Second Battle of Sirte, Battle of Mid-June, Battle of Mid-August ) between Allied navies and the Italian Regia Marina, during which the British, able to replace losses with warships redeployed from other theatres, finally gained the upper hand.
