About the monument to the 20th Massachusetts
The monument is a large boulder known as a "Puddingstone," native to Massachusetts and the official stone of the Commonwealth. It was brought for the monument's dedication from Roxbury, where many of the men of the regiment had played on such boulders as they grew up. The monument was dedicated on October 20th, 1885.

He was mortally wounded on July 2nd and died on the 4th. When Colonel Revere fell Lieutenant Colonel George N. Macy took command until he was wounded on July 3, losing his left hand. Captain Henry L. Abbott then took over the regiment.
