On the mainland, the governor of Spanish Louisiana, Count Bernardo de Gálvez, led a series of successful offensives against the British forts in the Mississippi Valley, first capturing Fort Bute at Manchac and then forcing the surrender of Baton Rouge, Natchez and Mobile in 1779 and 1780 [REF].
When Spain entered the war, Britain also went on the offensive in the Caribbean, planning an expedition against Spanish Nicaragua.
