Edward Hatch was born in Bangor, Maine, on December 22, 1832. After attending the local school, he spent two years at Norwich University, Vermont, went to sea for one voyage, and finally moved to Iowa to engage in the lumber business. On August 12, 1861, he was commissioned a captain of the 2nd Iowa Cavalry and ten months later, its colonel. The regiment was present with John Pope at New Madrid and Island No. 10, at the siege of Corinth, and in October, 1862, took part in the battle of Corinth, where Hatch commanded a brigade. The following spring he participated in Benjamin H. Grierson's famous raid through central Mississippi—a diversionary effort ordered by General Grant during his advance on Vicksburg. During the winter of 1863-64 he engaged in raiding North Alabama and in December was wounded in a skirmish at Moscow, Tennessee. Hatch was commissioned brigadier general of volunteers to rank from April 27, 1864, upon the recommendation of Grierson. While recovering from his wound he was placed in command of the cavalry depot at St. Louis but in June was ordered to Memphis and after the fall of Atlanta was engaged in opposing John B. Hood's invasion of Tennessee, commanding a division of cavalry under J. H. Wilson. (Shortly before this campaign it was alleged that Hatch, while sparring with N. B. Forrest in North Mississippi, plundered the home of ex-Secretary of the Interior Jacob Thompson at Oxford while Mrs. Thompson looked on.) The Federal cavalry during Hood's advance upon Nashville was clearly outclassed by the Confederates under Forrest; nevertheless, Hatch's division performed yeoman's service and its commander received the brevet of major general for gallantry during the campaign. Mustered out of volunteer service in January, 1866, Hatch was commissioned colonel of the 9th U. S. Cavalry upon the reorganization of the army on July 28 and was brevetted brigadier and major general the following year. His postwar career embraced mainly frontier service: department command in the Southwest, chairman of a commission which in 1878 forced the Utes to yield a portion of their Colorado reservation, and an unsuccessful chase after the Apache chief Victorio in 1880. General Hatch died at Fort Robinson, Nebraska, April 11, 1889, and was buried in the National Cemetery at Fort Leavenworth, Kansas.
