BRACKETT, Albert Gallatin, soldier, born in Cherry Valley, Otsego County, New York, 14 February, 1829. He removed to Indiana in 1846, and, during the war with Mexico, was first lieutenant in the 4th Indiana volunteers, attached to Lane's brigade, being present at Huamantla, Puebla, and Atlixco. On 16 July, 1848, he was honorably discharged. On 3 March, 1855, he became captain in the 2d United States cavalry, and, after raising a company in Indiana and Illinois, served on the Texas frontier, distinguishing himself in actions against the Comanche Indians. He was the first United States officer that crossed into Mexico in pursuit of hostile Indians. When General Twiggs surrendered to the confederates in 1861, Capt. Brackett escaped. He commanded the cavalry at Blackburn's Ford and the first battle of Bull Run, and in August, 1861, became colonel of the 9th Illinois cavalry, serving with credit through the Arkansas campaign, and being severely wounded at Stewart's Plantation, where he saved a valuable train from falling into the hands of the confederates. On 28 June, 1862, he was brevetted major in the regular army for services in the Arkansas campaign, and on 17 July received his full commission as major in the 1st cavalry. In 1863 he was chief of cavalry in the department of the Missouri, and in 1864 assistant inspector-general of cavalry, in the department of the Cumberland. He was engaged in the battles around Atlanta, was brevetted lieutenant colonel on 1 September, 1864, for his services there, and at the close of the war was brevetted colonel. After that time he served principally against hostile Indians in Nevada, Wyoming, and Arizona. He received his full commission as lieutenant colonel, 2d cavalry, on 9 June, 1868, and on 20 March, 1879, when commanding the district of the Yellowstone, was made colonel of the 3d cavalry. He was afterward assigned to the command of Fort Davis, Texas, and in March, 1886, was recommended by the congressional delegation of Indiana and Texas for promotion to the rank of brigadier-general. He has published "General Lane's Brigade in Central Mexico" (Cincinnati, 1854); "History of the United States Cavalry" (New York, 1865); and has written many magazine and newspaper articles, especially in regard to military affairs and the development of the country.
