Charles Ferguson Smith (April 24, 1807 – April 25, 1862) was a career United States Army officer who served in the Mexican–American War and as a Union General in the American Civil War. Early life and career Charles Ferguson Smith was born in Philadelphia, Pennsylvania, the son of Samuel Blair Smith, an army surgeon and a grandson of the celebrated Presbyterian minister Rev. John Blair Smith. He graduated from the United States Military Academy in 1825, and was commissioned a second lieutenant in the 2nd U.S. Artillery. As he rose slowly through the ranks of the peacetime army, he returned to West Point as an instructor and was appointed Commandant of Cadets as a first lieutenant, serving in that position from 1838 to 1843.

He was soon transferred to the Western Theater to command the District of Western Kentucky. He then became a division commander in the Department of the Missouri under Brigadier General Ulysses S.
