George Turnbull was born in 1728 at Blackadder Mains in the county of Berwickshire in Scotland close to the Scottish/English border.
[1] Turnbull was commissioned as a lieutenant in the British army in February 1756 and rose to captain of the 60th Regiment of Foot in November 1765.
[4] As a captain in the Loyal American Regiment, Turnbull took part in the capture of Fort Montgomery in October 1777, and was commissioned a lieutenant colonel a few days later.
General Henry Clinton’s after-orders at 9pm on 23 August directed the New York Volunteers and the British 15th and 46th Regiments to march to New Utrecht on the morning of 24 August, but new orders at 3pm on that date directed the two British regiments to return again to their former Encampments as soon as convenient.
In early July 1780 Turnbull ordered Christian Huck, to find the rebel Patriot Whig leaders and persuade other area residents to swear allegiance to the king.
