Arthur Lyon Fremantle
General Sir Arthur James Lyon Fremantle (11 November 1835 – 25 September 1901) 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 (from 2 April until 16 July 1863) 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. Early life and career Fremantle was born into a distinguished military family; his father, Lieutenant-General John Fremantle, had commanded a battalion of the Coldstream Guards, and had served during the Peninsular War and Waterloo Campaign, as well as acting as aide-de-camp to Lieutenant-General John Whitelocke during the abortive British invasion of Buenos Aires in 1807. Arthur's middle name, Lyon, came from his mother, Agnes Lyon. He was called "Arthur" after the Duke of Wellington, who had been the first witness at his parents' wedding in 1829. After his graduation from Royal Military College, Sandhurst, Arthur Fremantle was commissioned into the British Army in 1852, serving firstly as an ensign
