Chevalier de Johnstone

James Johnstone (1719), also known as Chevalier de Johnstone or Johnstone de Moffatt, was a Scottish memoirist who is best remembered for his ''Memoirs of the Rebellion in 1745 and 1746'', first published in 1820. The son of an Edinburgh merchant, he escaped to France after participating in the 1745 Jacobite rebellion.

He was commissioned a lieutenant in the French Colonial Army, and served in French North America for several years. Following the loss of Quebec to the British Army in 1760, Johnstone returned to France and became a civilian. Little is known of his later life, and he is thought to have died sometime between 1791 and 1800. Provided by Wikipedia
