p479 Biographical Sketch.a

Bvt. Major-General Andrew A. Humphreys was born Nov. 2, 1810, at Philadelphia, Pa. His grandfather and father were naval architects, and both became Chiefs of the Construction Bureau, U. S. Navy.b The former made the plans upon which were built "Old Ironsides" and her five sister frigates, which so proudly bore the stars and stripes to many victories in the War of 1812‑15 against Great Britain.

Young Humphreys entered the Military Academy before he was seventeen years old, and graduated therefrom July 1, 1831. After a short service in the artillery, during which he was engaged in the actions of Oloklikaha and Micanopy against the Seminole Indians in the Florida War, he resigned from the Army, Sep. 30, 1836, to become a Civil Engineer, under Major Bache, in the construction of a Light-house and Breakwater in Delaware Bay.

Upon the organization of the Corps of Topographical Engineers, he was appointed to rank as one of its First Lieutenants from July 7, 1838, and for six years was engaged in the duties of that branch of service.

Lieut. Humphreys, upon the application of Professor Indicates a West Point graduate and gives his Class.Alex. D. Bache, was detailed, in 1844, as his assistant in the Coast Survey Office, where his responsible duties became so laborious that his health gave way, compelling his relief at the end of five years.

In 1850, Capt. Humphreys was directed to make a Topographic and Hydrographic Survey of the Delta of the Mississippi River, with a view to its protection from inundation, and deepening the channels at its mouth. This required much careful study; the measurement of numerous cross sections, and volume of discharge of the river; the determination of the extent of floods, and how to lessen their effects; ascertaining the amount of riparian abrasions, and quantity and kind of sedimentary matter carried down; investigating every safe method of deepening the channel bars; and the solution of many vexed hydraulic problems which constantly presented themselves. His arduous labors of research and supervision were suddenly suspended, in the summer of 1851, by a sun-stroke. When partially recovered, he was permitted to visit Europe to study the deltas of its great rivers, and how they were protected by engineers against inundations.

Humphreys returned from abroad in 1854, when a new labor confronted him, — the supervision of the surveys of routes to the Pacific, and making the needful investigations of their comparative merits, with estimates of cost of railways by each. Lieut. Abbot, his assistant, says of his chief's grasp of this subject: "His mind worked like a beautiful machine, neglecting nothing, forgetting nothing, and so rapidly bringing order out of chaos that the work took shape visibly from day to day. The preliminary report was completed before Congress adjourned; and subsequent experience has amply confirmed the correctness of his conclusions and the wisdom of his recommendations."

The voluminous report on the Mississippi Delta Survey, which had been continued under Capt. Humphreys' direction by his assistant, Lieut. Abbot, was published by Congress in 1861, and such was its scientific value that it has been translated into most of the languages of Europe, for it is truly a mine for the hydraulic engineer.

In 1856, Humphreys, in addition to his many other duties, was made a Member of the Light-house Board, upon which he served ten years, but not continuously.

On the outbreak of the Rebellion, though Humphreys had proved himself a most meritorious officer, he was distrusted by those in power because of his intimacy with Indicates a West Point graduate and gives his Class.Jefferson Davis, under whom he had served when U. S. p480Secretary of War, and who had now become President of the Confederate States. However, in December, 1861, Humphreys was assigned to duty with the Army of the Potomac, in which by his brilliant soldierly qualities he rose from an Aide-de‑Camp to be the head of an Army Corps, with the rank of Major-General. Filling every position in which he was placed, — as Engineer, Chief of Staff, Division or Corps Commander, and serving in nearly every battle from Yorktown, in 1862, to Appomattox, in 1865, — he came out of the war with a reputation for gallantry, sound judgment, patriotic endeavor, and meritorious conduct rivaled by few and surpassed by none. At the desperate storming of Marye Heights, leading like a champion knight his command on this bloody field of Fredericksburg; in resolutely defending the exposed salient on the left of the line of battle at Gettysburg; and in the unremitting attack and pursuit of Lee's army to Appomattox C. H., — Humphreys displayed the intrepidity of a Ney and the cool self-reliance of a Masséna. "To courage of the brightest order, both moral and philosophical, he united the energy, decision, and intellectual power which characterized him in civil administration. These traits, joined to a thorough knowledge of strategy and grand tactics, fitted him for the highest military responsibilities."

The Civil War, in which Humphreys received three brevets for "meritorious services," being ended, he was further rewarded, Aug. 6, 1866, by the appointment of Chief of Engineers, U. S. Army. In this position, for thirteen years, he exhibited high administrative abilities, and, with the co‑operation of his able corps of officers, successfully conducted the operations on the numerous military and civil works under charge of the Engineer Department. Upon his own application he was retired, June 30, 1879, from active service in the Army, only to begin a new labor of faithfully recording the great deeds of the Army of the Potomac in the memorable campaigns of 1863, 1864, and 1865, of which he might have said magna pars fui.

Humphreys was a member of several learned societies at home and abroad; received, in 1865, the degree of LL. D. from Harvard University; and was one of the fifty original Corporators of the National Academy of Sciences.

As a subordinate officer, Humphreys was prompt in the performance of every duty, zealous and laborious in carrying out the orders of his superiors, and untiring in effort til his work was accomplished; and as a chief, though doing his full share of an allotted task, was generous in awarding the meed of praise to all under him. To his assistant, Lieut. Abbot, on the Mississippi Delta Survey, he accorded equal credit with himself by associating his name in the authorship of the able report thereon; and to all who won glory at his side on the battlefield he unstintingly assigned their full desert. It was this sense of justice and magnanimity which insured their confidence, affection, and highest efforts. Hence, as a general, he had the earnest support of his whole command, which, united to his own magnetic leadership, undaunted gallantry, loyalty of purpose, and skill in handling masses, made his army corps almost irresistible.

General Abbot, who, from his entrance into service, was most intimate with Humphreys till he died, Dec. 27, 1883, a period of nearly thirty years, says of his departed friend: —

"In official relations General Humphreys was dignified, self-possessed, and courteous. His decisions were based on full consideration of the subject, and once rendered were final. He had a profound contempt for everything which resembled double-dealing or cowardice. He scorned the arts of time-servers and demagogues, and when confronted with meanness took no pains to conceal his indignation, no matter what might be the rank or position of the offender. He felt the warmest personal interest p481in the success of his young associates, and often did acts of kindness of which they learned the results but not the source.

"In his social relations General Humphreys exerted a personal magnetism which can hardly be expressed in words. His manners were marked by all the graceful courtesy of the old school, while the unaffected simplicity and modesty of his character and the force and vigor of his ideas left an impression not easily effaced. He was a gentleman by nature, not merely by artificial polish, and no one could be thrown much in his society without recognizing the fact."

b His grandfather Joshua Humphreys was, as implied in the biographical sketch, the more celebrated of the two. A good look at him and his methods is provided by Eugene S. Ferguson in Truxtun of the Constellation, especially chapters 23 (pp109‑110), 25 (pp115‑117), and 27 (pp125‑130, passim).
