Donat Henchy O'Brien

Rear-Admiral '''Donat Henchy O'Brien''' (March 178513 May 1857) was an officer of the Royal Navy. He was the son of a Royal Navy captain who claimed descent from an ancient Irish king. O'Brien served as a midshipman during the French Revolutionary Wars and commanded a troop-carrying vessel during the Anglo-Russian invasion of Holland. He was afterwards appointed acting lieutenant and served as a master's mate on the frigate ''Hussar''. While returning to England in 1804, the ship was wrecked on the Île de Sein and O'Brien and other crew were captured by the French. O'Brien was imprisoned in France but escaped in 1808 and reached a British vessel at Trieste. He later wrote a book about his experiences.

O'Brien was afterwards promoted to lieutenant and served with the Mediterranean Fleet during the Napoleonic Wars. He distinguished himself in a number of boat actions, capturing numerous warships and cargo vessels. In 1818 O'Brien was posted to the South America Station and served there during the early part of the Argentine Civil Wars. In 1821 he returned to England. O'Brien never served at sea again but was promoted to rear-admiral in the reserve in 1852. Provided by Wikipedia
