The Revolutionary War is filled with stories of bravery, but many of its heroes have remained unknown. Major Philip Ulmer, captain of the gunboat Spitfire, is one of those heroes. He first enlisted as a sergeant in the Massachusetts militia in 1775 and rose through the ranks through his exemplary leadership, courage and devotion to duty. He was involved in almost every major event in the North, including the Battle of Bunker Hill, the Siege of Boston, the Battle of Lake Champlain, the Penobscot Expedition and the battles at Trenton, Princeton and Saratoga. He served under the command of many well-known generals, including Washington, Lafayette, Arnold, Gates and Knox. After the war, Ulmer forged a business partnership with Knox in Lincolnville, Maine, and was an original founder of that town. He answered the call of duty again during the War of 1812 as an intelligence officer with the local militia defending Penobscot Bay.
