On this day 14 May 1747 the First Battle of Cape Finisterre saw 14 British ships of the line under Admiral George Anson attack a French 30-ship convoy commanded by Admiral de la Jonquière during the War of the Austrian Succession. The British captured 4 ships of the line, 2 frigates and 7 merchantmen, in a five-hour battle in the Bay of Biscay off Cape Finisterre in northwest Spain. One French frigate, one French East India Company warship and the other merchantmen escaped.
