"General D. H. Hill, long a resident of Charlotte, is a native of South Carolina, but his services and fame are shared by North Carolina. He was educated at the United States Military Academy at West Point, at which he graduated in 1842, in same class with Generals Newton, Rosecrans, Rains, Whiting, Longstreet and others, and was commissioned a Lieutenant of Artillery. In 1847 he was promoted for gallant and meritorious conduct in the battles of Contreras and Churubusco, and the storming of Chapultepec, in the Mexican War. He resigned in 1849 and accepted a Professorship of Mathematics in Washington College, Lexington, Virginia. This he subsequently resigned and accepted a similar position in Davidson College, in this State, which he resigned to accept the Superintendency of the Military Institute at Charlotte, of which flourishing school he was the head, when the Civil War began.
"He is esteemed as an admirable and able professor, thoroughly versed in the studies of his department, and possessing the faculty of stimulating his students to their greatest efforts. He published in 1858 a text-book on Algebra, which Stonewall (T. J.) Jackson, then also a Professor in the Virginia Military Institute, regarded "as superior to any other work in the same branch of science."
The aforegoing sketch is nearly verbatim the sketch prepared by Colonel James G. Burr, and published in the "New South," edited and published at Wilmington by Edward A. Oldham.
