Point Pleasant Battery and the nearby Northwest Arm Battery were the first fortifications at Point Pleasant, built during the Seven Years War with France (1756 to 1763). Point Pleasant Battery, also known at various times as Breastwork Battery and Fielding’s Battery, was constructed hastily in 1762 in response to the seizure of St. John’s, Newfoundland by the French. It was intended to guard the main entrance to Halifax Harbour from attack from seaward. The battery initially consisted of a main redan with a subsidiary redan on its left flank, mounting five 24-pounders on the main right face and two 9-pounders on the right face of the flanking extension.
Point Pleasant Battery was rebuilt during American Revolution (1775 to 1783) and again during the French Revolutionary Wars (1793 to 1802). It retained its 24-pounder smooth-bore cannon (effective range about 1,500 yards) for service throughout the War of 1812 and the Napoleonic Wars (1803 to 1815) and increased to 32-pounders during the American Civil War in the 1860’s.
In the 1890s, defences at Point Pleasant Battery were upgraded with the addition of two linked searchlight emplacements, located some 80 metres west of the main battery, and an electric generating station was built close to the north side of the battery to power the lights. It was last used during World War I (1914 to 1918) with two 12-pounder quick-firing (QF) guns and searchlights as part of the anti-submarine harbour defences.
