Louverture’s unilateral occupation of Spanish Santo Domingo turned Bonaparte against him.

Evidence

Bonaparte’s opinion of Louverture, however, began to shift when news arrived of his takeover of Spanish Santo Domingo. The consul believed that this occupation, while allowed by the 1795 treaty between France and Spain, should have been carried out only under his orders. Bonaparte rescinded his promotion of Louverture and indeed took him off the list of those who were to be maintained as officers in Saint-Domingue. — Dubois, Laurent, Avengers of the New World_ The Story of…, 900
