Gen. John Buford perfectly executed the “Elements of Advanced Guard” taught at West Point, and basically saved the North with his delaying tactics.
I recently finished reading "Generals in Bronze" which essentially are the notes from the sculptor James E. Kelly who made this statue of Buford. Veterans in the group that commissioned the statue of Buford were furious that he wasn't portrayed on horseback. The reason Kelly gave for not portraying Buford mounted was because his cavalry fought as dismounted infantry.
Absolutely correct! Because of him the Union got that good high ground Lee spent so much of his army trying to eject them from.
