Bolívar, meanwhile, had also departed from Kingston to Port-au-Prince, where, on his promise of emancipating the slaves, Alexandre Pétion, the president of Haiti, offered him large supplies for a new expedition against the Spaniards in Venezuela. At Les Cayes he met Brion and the other emigrants, and in a general meeting proposed himself as the chief of the new expedition, on the condition of uniting the civil and military power in his person until the assembling of a general congress. The majority accepting his terms, the expedition sailed April 16, 1816 to the coast of Venezuela, with him as its commander and Brion as its captain. On May 2, 1816 he won his first victory over Spanish warships, in the Battle of Los Frailes.
