This part of Gibraltar did not experience much action during the Great Siege (1779-83) due to the fact that the enemy concentrated most of its fire power on the northern area of the Rock, with its connection to the isthmus and the ‘No Man’s Land’. The armament of the Bastion in 1771 consisted of the following:
South Front or Face - four iron 24-pounders, three iron 4-pounders, two brass 8-inch howitzers, six brass 8-inch mortars and one brass 5.5-inch mortar.
West Front or Face - eight iron 24-pounders, one iron 4-pounder, two brass 8-inch howitzers, two brass 10-inch howitzers and one brass 5.5-inch mortar.
In 1781 the bastion reported the following armament.
South Front or Face - two 32-pounders, four 24-pounders, one 4-pounder, two 3-pounders, one brass 8-inch howitzer, one brass 10-inch howitzer.
West Front or Face – ten 24-ponders, one 6-pounder.
