 Boyer, however, responding to a party on the east that preferred Haiti over Colombia, occupied the ex-Spanish colony in January 1822, encountering no military resistance.In this way he accomplished the unity of the island, which was only carried out for a short period of time by Toussaint Louverture in 1801.Boyer's occupation of the Spanish side also responded to internal struggles among Christophe's generals, to which Boyer gave extensive powers and lands in the east.
