Pretty terrible, because I heard no mention of the word "slavery" in it. In order to justify a war to end slavery, you do have to demonstrate that this was in fact, the mission of the army sent to invade, else people will get the idea that the war was about something else.
You know what, I'll bet we can find Irvin McDowell's orders somewhere, and if they mention "ending slavery", I'll eat them.
You people have been blowing the "We fought the war to end Slavery" trumpet for so long, I just wanted to make you blow it some more. I'm kinda liking the tune right about now.
You see what I mean?
