His life, from the cradle to the grave, was one of almost uninterrupted activity. He was born at Cotterstock, Northamptonshire. sometime in the year 1752, and was a soldier by right of inheritance. His father, Captain John Simcoe, after a life spent in his country's service, died in the St. Lawrence River, on board H. M. ship _Pembroke_, of miasmatic disease, contracted in exploring portions of the adjoining country for military purposes. His death took place only a few day's before the siege of Quebec, in 1759. He left behind him a widow and two children. The younger of these children did not long survive his father. The elder who had been christened John Graves lived to add fresh laurels to the family name, and at the time of his father's death was in his eighth year. Shortly after the gallant Captain's death his widow removed to the neighbourhood of Exeter, where the remaining years of her life were passed. Her only surviving son was sent to one of the local schools until he had reached the age of fourteen, when he was transferred to Eton. Few reminiscences of his boyish days have come down to us. He appears to have been a diligent student, more especially in matters pertaining to the history of his country, and from a very early age he declared his determination to embrace a military life. From Eton he migrated to Merton College, Oxford, where he continued to pursue his studies until he had entered upon his nineteenth year, when he entered the army as an ensign in the 35th regiment of the line. This regiment was despatched across the Atlantic to take part in the hostilities with the revolted American Colonies, and young Simcoe did his devoirs gallantly throughout the whole course of the war of Independence. In June, 1775, he found himself at Boston, and on the 17th of that month he took part in the memorable fight at Bunker Hill. He subsequently purchased the command of a company in the 40th Regiment, and fought at the battle of Brandywine, where he was severely wounded. Upon the formation of the gallant, provincial corps called "The Queen's Rangers," he applied for the command, and as soon as he had recovered from his wound his application was granted. Under his command, the Rangers did good service in many engagements, and fought with a valour and discipline which more than once caused them to be singled out for special mention in the official despatches of the time. Sir Henry Clinton, Commander-in-chief of the royalist forces in America, in a letter written to Lord George Germaine, under the date of 13th May, 1780, says that "the history of the corps under his (Simcoe's) command is a series of gallant, skilful, and successful enterprises. The Queen's Rangers have killed or taken twice their own numbers."
