Anglo-Spanish War: Battle of Gravelines: English naval forces under the command of Lord Charles Howard and Sir Francis Drake defeat the Spanish Armada off the coast of Gravelines, France.

The Anglo-Spanish War (1585–1604) was an intermittent conflict between Habsburg Spain and the Kingdom of England that was never formally declared. It began with England's military expedition in 1585 to what was then the Spanish Netherlands under the command of Robert Dudley, Earl of Leicester, in support of the Dutch rebellion against Spanish Habsburg rule.
