The Conway Cabal were 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 (which were often little more than criticisms and expressions of discontent with either Washington or the general course of the war) 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. No formal requests were ever made asking for Washington's removal as commander in chief. There was no sign of any formal conspiracy amongst the various malcontents, although Washington was concerned that there might be one. It was the only major political threat to Washington's command during the war.
