I called the side wearing the dark blue, almost blue-black, uniform, the Union army. I refuse to use that terminology any longer. Ulysses S. Grant, William T. Sherman, and more than two million soldiers didn’t fight in the Union army as though they belonged to an organization that fought only one war.17 An army relegated to the dustbin of history, as Karl Marx would say. No, the boys in blue fought in the U.S. Army for the United States of America.
Words certainly matter....U.S. Army for the United States vs the Confederacy certainly puts it into proper perspective more than the Union vs Confederacy.
