West Indies Campaign 1804–1810

Sir J.T. Duckworth's Action off San Domingo, Feb. 7 8th 1806, Thomas Whitcombe

By this time Spain a former enemy of the British and ally of the French was now invaded by French forces which led to the Peninsula war. Once the news of the invasion had reached the island, the criollos of Santo Domingo revolted against French rule and were later assisted by the Royal Navy of the United Kingdom who were now Spain's new ally.

By 1808 French colonial territories in the Caribbean were a drain on both the French and British navies. The fortified harbours on the islands and coastal towns provided shelter for French warships and privateers that could strike against British trade routes at will, forcing the Royal Navy to divert extensive resources to protect their convoys.[1] However, the maintenance and support of these bases was a significant task for the French Navy. It had suffered a series of defeats during the war that left it blockaded in its own harbours and unable to put to sea without attack from British squadrons waiting off the coast.[2] Cut off from French trade and supplies, the Caribbean colonies began to suffer from food shortages and collapsing economies, and messages were sent to France in the summer of 1808 requesting urgent help.[3]

Some of these messages were intercepted by the patrolling Royal Navy. Based on the description in those messages of the low morale and weak defences of the Caribbean territories, the decision was taken to eliminate the threat from the French colonies for the remainder of the war by seizing and occupying them in a series of amphibious operations. Command of this campaign was given to Rear-Admiral Sir Alexander Cochrane, who focused his initial efforts on Martinique, gathering a substantial force of ships and men at Barbados in preparation for the planned invasion.[4] While the main British forces concentrated in the Leeward Islands, smaller expeditionary forces were sent to watch other French colonies.
