Steam achievement Ruler of the Seas (Civ5) Ruler of the Seas

As Elizabeth, sink and destroy 357 enemy naval units, across any number of playthroughs.

357 is the total number of ships engaged at the Battle of Gravelines (1588), in which the English navy defeated the invading Spanish Armada during the Anglo-Spanish War. Possibly also a reference to Gilbert and Sullivan's comic opera, HMS Pinafore, in which Sir Joseph, the First Lord of the Admiralty, refers to himself both as the "monarch of the sea" and the "ruler of the Queen's navy".
