I believe it would be more correct to have John Bradstreet a Lt. Col. in the game. Only making Colonel after the war.

In 1755, Bradstreet, a captain, was appointed as Governor William Shirley's Adjutant-General. In 1756 he led a relief column to Oswego with supplies. Upon his return he was attacked by the French and Indians. He survived but his warnings to Gov. Shirley and Lord Loudon of the weak condition of Fort Oswego were lost in their power struggle. Fort Oswego was subsequently lost. On December 27, 1757 he was appointed Lt. Colonel. In 1758 he participated in the attack on Fort Carillon and he commanded the British forces of 3000 at the Battle of Fort Frontenac, which took control of Lake Ontario from the French on August 26, 1758. In 1759, he was made Quarter-Master-General.
After the war he was appointed Colonel in 1764 when he led a force of 1400 to re-inforce Fort Detroit. He was promoted to Major General on May 25, 1772.
