Answer :
This belief was supported by a fortunate confluence of traits that made Grant one of the most outstanding military commanders in American history.
Grant, an Ohio native, participated in the Mexican-American War after graduating from West Point (1846-1848). Grant, a brash and tenacious leader, was granted command of the American armies during the Civil War. He rose to fame after the war and received the Republicans' presidential nomination in 1868.
The Union Army commanders before Grant were significantly more skilled in the art and science of warfare. Since 1841, Winfield Scott had been in charge of the army and had experience dating back to the War of 1812. Early in the Civil War, George B. McClellan, a capable leader who created the Army of the Potomac, took over for the ailing Scott.
