Best remembered for a firsthand Civil War regimental history, this Boston-born writer turned his own service with the famed “Cadet Regiment” into a lively account of camp life, marches, and military routine.

by Charles Eustis Hubbard
Born in Boston in 1842, Charles Eustis Hubbard was the younger brother of Gardiner Greene Hubbard, a leading figure in early American communications. Though he is less widely known today than some members of his family, his name endures through a single notable work of military history.
Hubbard wrote The Campaign of the Forty-fifth Regiment, Massachusetts Volunteer Militia, a history of the 45th Massachusetts, often called the “Cadet Regiment.” The book draws on the regiment’s 1862–1863 service in North Carolina and is valued as a direct, readable account of Civil War soldiering from a Massachusetts perspective.
His writing is especially appealing for readers who enjoy eyewitness history: it stays close to the everyday experience of the regiment while still giving a clear sense of the larger campaign. Beyond that book, I couldn’t confirm a broader literary career from reliable sources, so it’s best to remember him chiefly as a participant-historian of the Civil War.
