"Formerly an old Church, but because used by the English in 1762 as a place of worship was considered desecrated, and abandoned."

He [General John Maunsell]  had earned his promotion, and in the next year, 1761, was commissioned major in the distinguished Sixtieth, or Royal Americans, in which Moncton, Wolfe's second in command (wounded in the battle at Quebec), was colonel. Under that gallant and generous commander he served at the siege of Martinique in 1761-62. He was in the trenches before Havana during the yellow fever months of 1762, and led the Thirty-fifth regiment into the breach of the Moro Castle, August 14, and carried it by storm. This seems to have ended his active military career in the field, as it ended for a time the wars of Great Britain in the west.

In recognition of his gallant achievement, he was gazetted lieutenant-colonel of the Eighty-third regiment, October 31, 1762. This regiment was disbanded in 1763, and he was transferred to the Twenty-seventh Foot (Inniskillings). Source: The magazine of American history with notes and queries
