William Augustus Bowles, born in 1763, was a Creek leader and adventurer who helped drive the Spanish from Florida. At the age of sixteen, he ran away from his Maryland Loyalist regiment to join the Creeks in Pensacola, but he returned a few months later with several Creek warriors. After the Revolution, he went to the Bahamas. There the British supplied him and the Creeks with arms in 1788. The next year, he went to London to petition King GeorgeIII with a plan to invade Mexico, but failed to gain support. He returned to the Lower Creeks in 1799 after several more exploits and issued a proclamation on October 31, expelling all U.S. and Spanish agents from the imaginary "state of Muskogee." In 1800, with a force of Lower Creeks and Seminoles, he captured the Spanish fort at St. Marks, but in 1803 the Upper Creeks turned him over to the Spanish. He was sent to Havana where he died in prison in 1805.
