Overview: Led by the Duke of Medina Sidonia, the Spaniards planned to sweep the Queen of England from her throne. All that stood in their way was a small navy led by Queen Elizabeth's cousin, Admiral Lord Howard, and the nation's favourite pirate, Francis Drake. In the summer of 1588, a vast Spanish invasion fleet sailed up the English Channel. England braced itself against invasion by the southern superpower and over the next 11 days, a series of ferocious sea battles ensued. Presenters Peter and Dan Snow demonstrate the different tactics the two sides used, how the English managed to fend off the bigger, more heavily armed ships, and how Spanish ships remained afloat despite being struck by English guns.
