Sickness and Rigaud’s campaigns crippled British forces in 1794

Evidence

Sickness decimated the Port-au-Prince garrison; in October 1794 fewer than half of the British troops in the city were fit to fight. In the south the British suffered a series of defeats at the hands of André Rigaud. In early October Rigaud took Léogane, a step on the road to Port-au-Prince. A few months later, on Christmas Eve, he attacked the British-held Tiburon, at the extreme west of the southern peninsula, routing and decimating the British garrison along with black troops under the command of Jean Kina fighting with them. — Dubois, Laurent, Avengers of the New World_ The Story of…, 627
