He was also rector of Killead and was chaplain to Viscount Nassereene. He took an active part in the siege of Derry in 1689. He was one of eighteen Anglican clergymen who both fought and held daily services in the beleaguered city. After the siege he accompanied his friend, the Rev. George Walker, to the Battle of the Boyne, where Walker was killed. John Campbell returned to Seagoe and is buried there.
