Regimental History

This page is the 2025-2026 working revision of the history of the 28th Massachusetts Volunteer Infantry

“The 28th Massachusetts….” is a substantial and splendid accession to the brigade. It has sinew, heart and soul.”
– Brig Gen’l Thomas Francis Meagher

Introduction. The 28th Massachusetts Volunteer Infantry was one of the most distinguished Regiment of the US Army during the American Civil War, in Federal service from January 1862 until mustering out in June 1865. Recruited largely in the Boston, Massachusetts area, and of largely Irish/Irish-American extraction, it was from the start, a distinctly “Irish” unit, with the nickname of the “Fág-an-Bealac” (Gaelic meaning “Clear the Way”) Regiment along with a distinct green Regimental Color. (See below links for more on the Regimental nickname and flags.)

After initial action in the Carolinas, the 28th Massachusetts ultimately joined the Army of the Potomac. The Regiment was constantly in action during its existence, participating in every major campaign in the eastern theater after the Peninsula Campaign – from the 2nd Battle of Bull Run to the final Grand Review of the Armies after the war’s victorious conclusion. It was a member of the famed Irish Brigade from November 1862, an organization it had been raised to join.

The regiment was seventh in total killed or died of wounds (250) among all Union regiments (the 69th New York, another Irish Brigade regiment, ranked sixth). In fact, of 1,703 men who enlisted in the regiment during the war, 1,133 were killed, wounded, or missing.
