Delos Bennet Sacket (1822–1885) was a career soldier promoted to Brevet Major General for gallantry during the American Civil War, and later appointed senior Inspector General of the United States Army with the rank of Brigadier General.
Delos graduated from the Military Academy at West Point in 1845, and was at once promoted to brevet Second Lieutenant and sent to Mexico with his regiment, the Second Dragoons. He fought in the front line in the ensuing Mexican-American War. In the charge upon the Mexican batteries at Palo Alto and at the battle of Resaca de la Palma his gallant and meritorious conduct caused him to be breveted First Lieutenant. He was also engaged in the battle of Monterey, in September, 1846. A brevet then counted for something, as it was only given for distinguished bravery under fire.
His obituary in the New York Times said of him, “Gen. Sacket was a man of fine presence, courtly in manner and soldierly in address, and was one of the most popular officers in the army.”
