Admiral Sir Edward Thornbrough, GCB (27 July 1754 – 3 April 1834) was a senior, long-serving veteran officer of the British Royal Navy during the late eighteenth and early nineteenth century. He saw action in the American Revolutionary War, the French Revolutionary Wars and the Napoleonic Wars, being wounded several times and once captured by American forces after a shipwreck. During the wreck, his conduct towards American prisoners aboard his ship was considered so exemplary that the American authorities later released him without parole or exchange.
