 After falling to Britain during the Seven Years' War, the Aulac area became part of the Tantramar farming district in the township of Sackville.The Intercolonial Railway constructed its mainline connecting Moncton, New Brunswick with Truro, Nova Scotia in 1872, with the railway line curving around the ridge below the fort.In the 20th century, roads across the marshes passed up and over the Aulac Ridge, as did a road running the length of the ridge toward Port Elgin.
