Arthur James Lyon Fremantle

General Sir Arthur James Lyon Fremantle was a British Army officer and a notable British witness to the Battle of Gettysburg during the American Civil War. Whilst holding the rank of "Captain and Lieutenant Colonel" he spent three months in North America, travelling through parts of the Confederate States of America and the Union. Contrary to popular belief, Colonel Fremantle was not an official representative of the United Kingdom; instead, he was something of a war tourist.
