Early life and career

Henry Eustis was born at Fort Independence near Boston, Massachusetts. His father Abraham Eustis, a career army officer, was stationed there at the time. Henry graduated from Harvard University in 1838 and then attended the United States Military Academy at West Point, New York. After graduating first in his class in 1842, Eustis was assigned to engineering roles, including working on several improvements to the unfinished Fort Warren in Boston Harbor. Eustis taught engineering at West Point from 1847 to 1849. He resigned on November 30, 1849, and took an appointment teaching engineering at Harvard.

Civil War

After the Civil War broke out, Eustis joined the volunteer infantry being raised in Massachusetts. He was commissioned as the new colonel of the 10th Regiment Massachusetts Volunteer Infantry on August 21, 1862. (The regiment had been mustered into the service on June 21, 1861.) He joined the division of Brig. Gen. Darius Couch in the IV Corps, Army of the Potomac. Couch's division served in the Maryland Campaign, but it was not present at the Battle of Antietam.

After the battle, the division became 3rd Division of the VI Corps under Brig. Gen. John Newton. Eustis participated in the Battle of Fredericksburg in the brigade of Brig. Gen. Charles Devens. He then served under Col. William H. Browne in the Chancellorsville campaign. When Browne was wounded at the Battle of Salem Church, Eustis succeeded to command of the brigade. He led the brigade at the Battle of Gettysburg, where his units were in reserve. Eustis became a brigadier general on September 12, 1863. He served in the autumn campaigns of 1863 under Brig. Gen. Henry Dwight Terry, who had taken over after Newton became commander of I corps.

In the reorganization of the Army of the Potomac preceding Ulysses S. Grant's Overland Campaign in 1864, Eustis's brigade was moved to the 2nd Division of VI Corps under Brig. Gen. George Getty. Eustis commanded his brigade in the Battle of the Wilderness. After Maj. Gen. John Sedgwick was killed at the Battle of Spotsylvania, Brig. Gen. Horatio Wright became the corps commander. Brig. Gen. David Allen Russell took over Wright's 1st Division and Eustis was moved to the command of Russell's former brigade. He led this brigade at Spotsylvania and the subsequent actions of the army through the Battle of Cold Harbor. Eustis resigned his commission on June 27, 1864, for reasons of "health." It is reported that he was compelled to resign because of his addiction to opium, which caused neglect of military duties.

Post-war

Eustis returned to teaching at Harvard and wrote several technical articles, as well as a genealogy of his family in 1878. He became the dean of the Lawrence Scientific School, later the Harvard School of Engineering and Applied Sciences.[1] He was holding that post when he died in Cambridge, Massachusetts, on January 11, 1885.

General Eustis was buried at Mount Auburn Cemetery in Cambridge.

gollark: I've made a bit of a frontend for my search engine thing. Though it can't actually do search yet, only crawl/index/whatever pages.
gollark: Basically, if I want to run a search it just goes `SELECT * FROM page_tokens WHERE token = 'one token in search query'` or something like that, and it now has a list of pages with the right token, and SQLite can execute this query relatively fast.
gollark: I mean, as far as I can tell there isn't really a faster *and* more storage-efficient way to do search than the inverted-index page_tokens thing.
