A large allied fleet led by the Regia Marina attacked the enemy-held port at Durazzo, Albania.

Allied forces involved primarily were Italian though British, American and Australian warships also participated.

From 15 to 29 September 1918, French General Louis Franchet d'Espèrey in command of a large allied army, campaigned in Macedonia.

Fearing the remaining enemies would fall back on the Austrian-held port of Durazzo for supplies, Franchet d'Espèrey requested that an allied naval fleet be assembled to attack Durazzo and thus prevent the city from supplying retreating enemy forces.

Franchet d'Espèrey's request was approved and the Italian Regia Marina accepted the responsibility of leading the attack.

The Allies divided their fleet into two forces, one for bombardment and the other for screening the attacking ships from enemy submarines.

The Second Battle of Durazzo began on the morning of 2 October 1918, when British and Italian aircraft attacked by bombarding enemy troop concentrations and artillery batteries while the fleet was still steaming across the Adriatic.

Meanwhile, the MAS boats and some American and British vessels attacked the three Austro-Hungarian naval ships, SMS Dinara, Scharfschütze and No.

The Austro-Hungarian hospital ship Baron Call was stopped and searched by British destroyers before being allowed to proceed.

129 was fired on by the enemy shore batteries, the closest shot landed about 50 yards (46 m) from the vessel, but the Americans suffered no casualties in the battle.

The submarines managed to damage at least one allied light cruiser; HMS Weymouth was struck by a torpedo from U-31 under a Lieutenant Rigele, which blew off a large portion of her stern and killed four men.
