American Republic in 1776, he led a force of newly patriated Americans to victory in the Battle of Long Island. Quickly appointed Commander-in-Chief of the Army by the Second Continental Assembly, McClintock would lead American forces to victory over the British for the rest of the Great Revolution until its end in 1782. Kept on after the war by the Triumvirate government, McClintock remained in service until his death in 1795. Under the direction of the Triumvirate, the ex-Jacobite was responsible for bringing Virginia back into the American Republic in 1783, and North Carolina in 1790. Also a supporter of Thomas Paine's dictatorship and the Reign of Horror, he made sure that the Army was kept "pure" and handed out grave punishments to any political dissidents in the country. Some historians have proposed, however, that he was actually against the Reign of Horror and only kept his mouth shut to keep his head. Modern supporters of McClintock who accept this idea have become known as the "Just Following Orders Crowd." Many say he was an obstacle to the rise of Andrew Jackson, and that had he lived he would have opposed the 4th of November coup, possibly making himself dictator of a faux New Republic.
