Battery B, 4th US Artillery was closely related to the Iron Brigade. General John Gibbon (the second commander of the brigade) once commanded this battery for the regular army. When the battery was low on men Gibbon allowed men from the Iron Brigade to man the guns. The battery was originally formed in March 1821 and had six 12lb Napoleon smoothbore guns. Although some authors don't consider the battery as strictly a member of the Brigade, it's performance firing by the side of this brigade and manned by many western volunteers, earn it recognition, gratitude, and a place on the list.
