Horatio Lloyd Gates was a British-born American army officer who served as a general in the Continental Army during the early years of the Revolutionary War. He took credit for the American victory in the Battles of Saratoga (1777) – a matter of contemporary and historical controversy – and was blamed for the defeat at the Battle of Camden in 1780. Gates has been described as "one of the Revolution's most controversial military figures" because of his role in the Conway Cabal, which attempted to discredit and replace General George Washington; the battle at Saratoga; and his actions during and after his defeat at Camden.
