Charles Grey, 1st Earl Grey, KB, PC (circa 23 October 1729 – 14 November 1807) served as a British general in the 18th century.
A distinguished soldier in a generation of exceptionally capable military and naval personnel, he served in the Seven Years' War of 1756-1763, taking part in the defeat of France.
He later served in the American War of Independence (1775–1783) and in the early campaigns against France during the French Revolutionary War.
Following the Battle of Paoli in Pennsylvania in 1777 he became known as "No-flint Grey" for, reputedly, ordering his men to extract the flints from their muskets during a night approach and to fight with the bayonet only.
