In 1776, the Ninety-Six District militia split into Loyalist and Patriot factions. Williams was made a lieutenant colonel of a regiment, but he had to recruit and train the new men. He succeeded in organizing a militia group, but pressure from Britain and her Indian allies meant that Williams always had to leave some troops behind for home defense. Williams led forces of local men into action at nearby Briar Creek and Stone Ferry, and as far afield as the expedition to the Second Battle of Savannah.
