Emboldened by the sudden retreat of the Haitian army, the Dominicans counter-attacked. Their flotilla went as far as Dame-Marie, which they plundered and set on fire. Soulouque, now self-proclaimed as Emperor Faustin I, decided to start a new campaign against them. In 1855, he again invaded the territory of the Dominican Republic. But owing to insufficient preparation, the army was soon in want of victuals and ammunition. In spite of the bravery of the soldiers, the Emperor had once more to give up the idea of a unified island under Haitian control. After this campaign, Britain and France intervened and obtained an armistice on behalf of the Dominicans, who declared independence as the Dominican Republic.
