WHIPPLE, Amiel Weeks, soldier, born in Greenwich, Massachusetts, in 1818; died in Washington, D. C., 7 May, 1863. He studied at Amherst, was graduated at the United States military academy in 1841, was engaged immediately afterward in the hydrographic survey of Patapsco river, and in 1842 in surveying the approaches to New Orleans and the harbor of Portsmouth, New Hampshire In 1844 he was detailed as assistant astronomer upon the north eastern boundary survey, and in 1845 he was employed in determining the northern boundaries of New York, Vermont, and New Hampshire. In 1849 he was appointed assistant astronomer in the Mexican boundary commission, and in 1853 he had charge of the Pacific railroad survey along the 35th parallel. In 1856 he was appointed engineer for the southern light-house district and superintendent of the improvements of St. Clair flats and St. Mary's river. At the opening of the civil war he at once applied for service in the field, and was assigned as chief topographical engineer on the staff of General Irvin McDowell. In this capacity he was the author of the first maps of that part of Virginia that were issued during the war, and performed creditable service at the first battle of Fredericksburg. Upon the second advance of the army tie was attached, as chief topographical engineer, to the staff of General George B. McClellan, but, being appointed brigadier-general of volunteers, was recalled in May, 1862, and assigned to the command of the defences of Washington south of Potomac river. His service here was so well performed that he received in orders the thanks of the president of the United States. His division was assigned in October, 1862, to the 9th corps, and took part in the movement down the eastern base of the Blue Ridge, upon the skirts of Lee's retreating army. At Waterloo his division was attached to the 3d army corps, and he led it at the battle of Fredericksburg. At the battle of Chancellorsville it was much exposed, and suffered more, probably, in that engagement than any other division of the army. He was shot on Monday, 4 May, 1863, when the battle was practically at an end, and, living three days, was appointed major-general of volunteers for gallantry in action, tie had received the brevets of lieutenant-colonel for the Manassas campaign, colonel for Fredericksburg, brigadier-general for Chancellorsville, and major-general for services during the war--all in the regular army.--His son, CHARLES WILLIAM was graduated at the United States military academy in 1868, and is now chief ordnance officer of the Department of the Missouri, with the rank of captain.
