This is a transcription of prisoner of war records of American sailors, marines and merchantmen which were transcribed from the ledgers of the British Admiralty during the War of 1812. These men were either captured off the coast of western Europe, including the western Mediterranean Sea, or who were taken off British warships and merchantmen at the beginning of the war. The information is grouped by location: Portsmouth lists 1,509 prisoners; Gibraltar lists 752 prisoners; Malta lists fifty-five prisoners; and Stapleton lists 421 prisoners. This volume has an alphabetical listing of names, a numeric listing by prisoner number, and a crew listing by ship. The ledgers from Portsmouth include a partial listing of the crews from the U.S. Schooners Growler and Julia, which were captured on Lake Ontario, the crew of the U.S. Revenue Marine Cutter James Madison, and the crews from three prize ships of the U.S. Frigate President. Mr. Johnson is a lineal descendant of seven veterans of the War of 1812, and he is the past president of the Society of the War of 1812 in the State of Ohio (2008-2011). He is currently the Registrar General for the General Society of the War of 1812, and has served as the Historian General (2011-2014) and the Archivist General (2014-2017) for this society.
