Lieutenant Henry Walker (1790-1854), entered the Navy on 1 March 1805 as a First Class Volunteer in the 98-gun Temeraire (Captain Eliab Harvey) whose exploits in the battle of Trafalgar are the legendary finishing of the battle dismasted and helpless but with a French prize on either side of her. Transferring into the Africa (Captain Bayntun) in 1806, Walker -- by now a Midshipman -- was present at the unsuccessful assault on Buenos Ayres in 1807 and thereafter served on several different stations in a number of vessels. In February 1813, with the rank of Acting-Lieutenant, he was given command of the schooner Cuttle on the North American Station, transferring shortly afterwards into the sloop Mohawk in which he was present on the expedition up the Elk River, in Chesapeake Bay, between 29 April and 3 May 1813, during the Anglo-American War of 1812-14. The first boat action involved the destruction of five American ships along with substantial stores, whilst the second involved the destruction of a shore battery which opened fire on the boat crews as they were returning down river. Promoted Lieutenant at the end of May 1813, he was placed on half-pay in 1815 and saw no further service at sea. This lot is sold with the transcript of a letter from the recipient (to his father) giving his personal account of Trafalgar.
