Baker's Brigade was a brigade organized and led by Colonel Edward D. Baker, who was also a senator from Oregon. Baker was killed during the Battle of Ball's Bluff.
The Tammany Regiment, also known as the Jackson Guards, was the nickname of the 42nd New York Volunteer Infantry Regiment, which had been organized in Great Neck (Long Island) by the Tammany Society. It was mustered in on June 22, 1861 and left for Washington, D.C. the following month. The regiment was attached to Stone's brigade, Division of the Potomac, in August of 1861, and then became part of Gorman's Brigade (Stone's division, Army of the Potomac) on October 15, 1861; soon after the regiment saw action at the Battle of Ball's Bluff on October 21, 1861.
