Colonel Henry Eustis

Colonel Henry Eustis commanded the brigade at the Battle of Gettysburg. Eustis  (West Point Class of 1842) was a career army officer and the son of a career army officer. He graduated from Harvard in 1838 then graduated first in his class at West Point. Eustis had spent his career on engineering projects and taught engineering at both Harvard and West Point.

In August of 1862 Eustis left his teaching position and became colonel of the 10th Massachusetts Volunteer Infantry Regiment. Eustis commanded the regiment at Antietam, where it was in reserve, and Fredericksburg. At the Battle of Salem Church during the Chancellorsville Campaign he took command of the brigade as senior brigadier. Eustis would continue to command a brigade in the 6th Corps through the bloody Overland Campaign until he resigned in June of 1864, officially for reasons of health but reportedly due to an opium addiction. He returned to teaching, becoming dean of Harvard’s Lawrence Scientific School.
