Obituary Notice.

General Stewart L. Woodford at the decoration of the grave at West Point of General Gillmore, May 29, 1888, by the U. S. Grant Post, Grand Army of the Republic, said of him:—

Gillmore graduated from the Military Academy at West Point in 1849, at the head of his class, and was appointed Brevet Second Lieutenant in the Engineer Corps. For the next three years he was engaged on works of construction; then for four years he was stationed here as Assistant Instructor; then for five years at New York on Engineering duty; then during almost the entire Civil War he was in active service, first at Hilton Head, South Carolina; next at the Siege and Capture of Fort Pulaski, Georgia; next with troops in the field in West Virginia and Kentucky; next in the Occupation of Morris Island, the Bombardment of Sumter, and the Capture of Fort Wagner; and next with the Army of the James in Virginia, and again in the administration of Department of the South during the spring, summer, and autumn of 1865. After peace came he was constantly on service in the Engineer Corps of the Army, and engaged in its most important duty and work. Meanwhile, as a scientific author and writer on subjects connected with his special studies of ordnance and engineering, he took the place of a recognized authority in our own country and in foreign lands.

"As a scientific, scholar­ly, and profound thinker on military problems, I believe that he ranked in ability, learning, and reputation among the really great engineers, not only of our own Army but even of the world. He was solid, not superficial; thorough and yet brilliant; sound in judgment, fertile in resource, persistent in purpose, honorable in life. His record in the Military Academy as a student, his work in peace as an engineer, and his service in war, make him a worthy type of the American scholar and soldier.

"So long as the waves shall beat upon the sands of Morris Island; so long as the debris of Sumter shall crumble at the feet of her newly erected walls; so long as the flag of the Nation shall float above that fortress which marked beginning of fraternal strife, — the records of our army and of our republic shall keep the name of Quincy A. Gillmore as a courteous gentleman, a wise scholar, a loyal citizen, a good soldier, and a truly great military engineer."
