Lieutenant Small went to North America to fight for Great Britain against French Canadian forces in the
Seven Years' War. On that front, the war became known to the colonists of the
Thirteen Colonies as the
French and Indian War, referring to France and its Native American allies. Small fought at the
Battle of Fort Oswego in New York. Two years later, in 1758, he fought at the
Battle of Ticonderoga, also in New York, under General
James Abercrombie. Following the defeat, he accompanied
General Amherst on his successful expedition to
Lake Champlain. He was with him at the
Surrender of Montreal in 1760. In
Montreal, Small was placed in charge of the French prisoners and took them to
New York. General Amherst had great confidence in him, and frequently used him "on particular services". In 1762, Small was promoted to captain. He sailed with his regiment to take part in the
Invasion of Martinique and the
British expedition against Cuba, as Great Britain tried to take more power in the Caribbean during the Seven Years' War. Following the
Treaty of Paris in 1763, Captain Small was placed on half-pay. According to General Stewart, he was almost immediately put on the full-pay list of the
21st North British Fusiliers. When the
Black Watch left in 1767 for Europe, most of the men of that regiment, who had earlier volunteered to stay in North America, joined the Fusiliers in order to serve under Small. He was "deservedly popular" with them. That same year, Small was appointed
brigade major to the forces in North America and returned there. It may have been during the interval between the Seven Years' War and the
American Revolution that Small began to acquire his estate, Selmah Hall, in
Nova Scotia. He later bequeathed part of it to his first cousin, friend, and heir
General John Robertson Reid. During this period, Small became interested in local politics and formed friendships with several influential Anglo-American politicians. ==American Revolution==
