This is a decidedly unremarkable educational video on the American Civil War until the 5:05 mark. At that point, Colonel Ty Seidule, Professor of History at the United States Military Academy at West Point, makes the following point:
As a soldier, I am proud that the United States army, my army, defeated the Confederates. In its finest hour, soldiers wearing this uniform-almost two hundred thousand of them former slaves themselves-destroyed chattel slavery, freed 4 million men, women and children from human bondage, and saved the United States of America.
I have trouble imagining any member of the U.S. army today disagreeing with this statement. But I also can’t imagine anyone today outside of the military disagreeing with it as well.
