John Hamilton (1724 in Annapolis Royal – 1802 in Waterford, Ireland) was a British army officer of the 40th Regiment of Foot who fought in both King George's War and Father Le Loutre's War. He was eventually captured by a Mi'kmaq militia. He was an important prize for the Mi'kmaq because of his connections with the Nova Scotia establishment, his father and father-in-law being members of the Nova Scotia Council. He was also an artist and attempted to negogiate peace between the Mi'kmaq and British.
He participated in the Siege of Annapolis Royal (1745) during King George's War. He applied for compensation when his property was destroyed in the defence of the town.
He was taken prisoner at the Siege of Grand Pre during Father Le Loutre's War in Nova Scotia (1750). The Mi'kmaq militia captured Lieutenant John Hamilton and eighteen soldiers under his command (including British officer John Handfield's son), while surveying the fort's environs. He was imprisoned in Quebec for two years before he was able to negotiate for the freedom of himself and 60 other prisoners. He was helped to gain his release by both his father Otho Hamilton and his father-in-law William Shirriff, both of whom were members of the Nova Scotia Council. Jean-Louis Le Loutre had paid Mi'kmaq ransom for Hamilton's release. He also was traded for the daughter of an Indian chief that John Gorham had imprisoned in Boston at his own residence with his daughter. Upon his return he married his second wife, daughter of his commander John Handfield.
In 1754-55, Hamilton was supportive of Le Loutre and Chief Paul Laurent trying to negotiate a peace with the British.
