This chart is about the Armada, not the famous one from 1588, but the little known one of 1779. It formed part of the Franco-American alliance during the American War of Independance and was an attempt by the French and Spanish to invade Britain. The plan was to capture the Isle of Wight and then the naval base at Portsmouth. Ultimately it failed, but it did force the British to reinforce the Channel ports. The map is engraved by Edward Sudlow (fl.1784-93) and drawn from a plan in John Harrison’s edition of Rapin’s ‘History of England’. The chart extends from Plymouth in the east to the Scilly Islands in the west.The text panel to the top left describes the ship movements, wind directions and times in detail.
