I have just been shown this from someone and wondered if it may be of use here The documents photographs below cover British prisoners held in the United States due to the War of 1812. This includes not only Army and Navy prisoners but also those taken on merchant vessels and privateers. http://www.1812privateers.org/GB/prisoners.htm also you can search for merchant ships and privateers with a unique list of Lloyd's List marine news for the war. http://www.1812privateers.org/Bibliography/Bibliography.htm Edna Palmer
