Thomas Conway served as a major general in the American Continental Army during the American Revolutionary War. He became involved with the alleged Conway Cabal with Horatio Gates. He later served with Émigré forces during the French Revolutionary Wars.

The Conway Cabal was a group of senior Continental Army officers in late 1777 and early 1778 who aimed to have George Washington replaced as commander-in-chief of the Army during the American Revolutionary War. It was named after Brigadier General Thomas Conway, whose letters criticizing Washington were forwarded to the Second Continental Congress. When these suggestions were made public, supporters of Washington mobilized to assist him politically. Conway ended up resigning from the army, and General Horatio Gates, a leading candidate to replace Washington, issued an apology for his role in events.
