The 20th Massachusetts Infantry was sometimes called “The Harvard Regiment” due the high number of men in its ranks who attended the university. Organized in Aug and Sept 1861, the regiment saw its first action at the battle of Ball’s Bluff in Oct 1861. The regiment’s Colonel, William R. Lee, was taken prisoner but would be exchanged and rejoined the 20th Mass. the following spring. Lee would resign his position just following the horrible clash at Fredericksburg, Virginia, and command would fall to Paul Joseph Revere, a relative of the Revolutionary War hero, Paul Revere.
At Gettysburg, the regiment arrived on the field on July 2 but “did not fire a shot” per the after action report of Capt. Henry L. Abbott. “Col. Paul Joseph Revere was mortally wounded and some ten or eleven men were killed.” The following afternoon, the 20th Massachusetts was a recipient of the rebel cannonade preceding “Pickett’s Charge” during which the regiment lost a handful more of their men. Upon the rebel advance, Abbott wrote the men, “were kept lying on their bellies, without firing a shot, until orders to fire came from Colonel Hall, commanding the brigade, the enemy having got within 3 or 4 rods of us, when the regiment rose up and delivered two or three volleys, which broke the rebel regiment opposite us entirely to pieces, leaving only scattered groups. When the enemy’s advance was first checked by our fire, they tried to return it, but with little effect, hitting only 4 or 5 men.
“We were feeling all the enthusiasm of victory, the men shouting out, ‘Fredericksburg,’ imagining the victory as complete everywhere else as it was in front of the Third Brigade, when Colonel Macy drew my attention to a spot some rods to the right of us, near a clump of trees, where the enemy seemed to have broken in…” The regiment then forced their way toward the copse of trees and Capt. Abbott continued on. “When they arrived there, there was a very thin line contending with the enemy, who was behind a rail fence, with the exception of a small number that climbed over, who were speedily dispatched. The enemy poured in a severe musketry fire, and at the clump of trees they burst also several shells, so that our loss was very heavy, more than half the enlisted men of the regiment being killed or disabled, while there remained but 3 out of 13 officers. Moreover, the contest round this important spot was very confused, every man fighting on his own hook, different regiments being mixed together, and half a dozen colors in a bunch, it being impossible to preserve a regimental line.”
When the smoke cleared, the rebel force had been driven back and the survivors left behind taken prisoners of war. The 20th Massachusetts lost 30 men killed, 94 wounded, and 3 missing in action. By the end of the war, the 20th Massachusetts Infantry would suffer the highest casualty rate of any Massachusetts regiment and the fifth highest of any Union regiment.
This monument in memory of the “Harvard Regiment” is made of Puddingstone, the official rock of Massachusetts. This chunk was brought from Roxbury, MA, to Gettysburg, PA and the memorial was dedicated on 20 Oct 1885. 🇺🇸
