Henry Morgan's raid on Lake Maracaibo, the Spanish Armada de Barlovento is defeated by an English Privateer fleet led by Captain Henry Morgan.

Henry Morgan's raid on Lake Maracaibo, also known as the Sack of Maracaibo and the Battle of Lake Maracaibo, was a military event that took place between 16 March and 21 May 1669 during the latter stage of the Anglo-Spanish War. English privateers commanded by notable Buccaneer Henry Morgan launched an attack with the purpose of raiding Spanish towns along the coastline inside of Lake Maracaibo in the Spanish Province of Venezuela.

The Armada de Barlovento was a military formation that consisted of 50 ships created by the Spanish Empire to protect its overseas American territories from attacks from its European enemies, as well as attacks from pirates and privateers.

Sir Henry Morgan was a Welsh privateer, plantation owner, and, later, the lieutenant governor of Jamaica. From his base in Port Royal, Jamaica, he and those under his command raided settlements and shipping ports on the Spanish Main, becoming wealthy as they did so. With the prize money and loot from the raids, Morgan purchased three large sugar plantations on Jamaica.
