What do You think about Cochrane: Britannia's Sea Wolf (2002)?
He served under four flags: those of Britain, Chile, Brazil, and Greece. He was perhaps the greatest ship (rather than fleet) commander in all of naval history. Yet Lord Cochrane is relatively unknown outside of Britain, Greece, and South America. Donald Thomas with his book Cochrane: Britannia's Sea Wolf attempts to redress that. Like many exceedingly brilliant military figures, Cochrane frequently ran afoul of politicians and was frequently persecuted and mulcted by them. He was accused of stock fraud in a patently ludicrous trial by an unfair judge, Lord Ellenborough, served time in prison, was stripped of his title of Knight of the bath, and removed from the navy list.That did not dismay the Scottish sea wolf, who helped Chile and Peru win their independence from Spain by destroying that country's Pacific Fleet. When he had done all he could there, he moved on to Brazil to fight for Don Pedro I. When that was over, he joined the struggle for Greek independence, where he was prevented from winning by the factionalism of the Greek politicians.In the end, under Queen Vicoria, he regained all his honors and died rich in years and reputation.
