28th Massachusetts 1st Model Regimenal Flag, nylon with grommets. The 1st Model flag did not have "28th" on it, but had "4th Regt." meaning they were the 4th regiment of the Irish Brigade. Confusing right. The Union flag that they carried had "28th Regt. Massachusetts" on it. The gaelic motto translates, "They will never retreat from the charge of lances".
