It is alleged that, in the Siege of Stirling Castle in 1651 by General Monk, during the Wars of the Three Kingdoms, the church and churchyard suffered damage from musket shots, which is still visible. However, all damage is opposite the south rampart of Stirling Castle, and as damage clusters around the slot windows, it is clearly just a "game" of soldiers firing from the castle to get the musket ball through the slot. Were it from an attacking force damage would be on the south side, which it is not. James Guthrie, who was later executed, was the minister at the time. Soon after, Guthrie with two or 3 elders appointed Robert Rule as Guthrie's successor which caused a schism in the congregation and a dividing wall was built which stood until 1936.
