The Queen's Rangers 1776 1st American Regiment
The Queen's Rangers, raised by Major Robert Rogers, was designated by King George III in 1779 as the 1st American Regiment in recognition of its outstanding service to the Crown. The regiment along with other troops laid down arms at Yorktown on October 19, 1781. Two years later it was disbanded and many of the Rangers went to British North America as United Empire Loyalists. The corps, re-established under Colonel John Graves Simcoe, first Lieutenant-Governor of Upper Canada, provided service in the newly-settled province between 1792 and 1802. The present-day Queen's York Rangers (1st American Regiment, Royal Canadian Armoured Corps) of Toronto, Ontario, traces its lineage back to the Queen's Rangers and Rogers' Rangers.
