The Spanish Armada is defeated. The Spanish fleet was led by the Duke of Medina Sidonia and its purpose was to overthrow Elizabeth I, to reinstate Catholicism in England and to end England's support for the Dutch Republic to prevent attacks by English and Dutch privateers against Spanish interests in the Americas.
The English fleet was under the command of Charles Howard, 2nd Baron Howard of Effingham. His second in command was Sir Francis Drake. The Spanish Armada defeat is considered one of England's greatest military achievements. More
