Wherein the Emancipation Proclamation was issued after Gettysburg and Vicksburg

This is the post that prompted this. He claims that The Emancipation Proclamation was issued at the decisive victories of Gettysburg and Vicksburg. It currently sits at +23.

This is not an issue with moratorium issues, even though it happened in a moratorium-related thread. It's that people claimed that the Emancipation Proclamation was issued after Gettysburg and Vicksburg, and then below it were OTHER people giving the rationale behind issuing the Emancipation Proclamation AFTER GETTYSBURG AND VICKSBURG. I seriously had to check to see if I was still living in the same universe. It's like if people claimed that D-Day came before Torch, and then a completely different set of people below it talked about why it made sense to invade North Africa after France.

The Emancipation Proclamation was presented to the cabinet on September 22, 1862 after Lee's first invasion of the north came to a halt at the back-and-forth bloody-as-hell Battle of Antietam. It was a strategic victory for the Union, despite numerous mistakes by the ever-timid McLellan that could have made it a much more one-sided affair. Lincoln had been waiting for some type of Union victory to issue the Proclamation after and he decided that Antietam would do.

It was issued on January 1, 1863. Gettysburg and Vicksburg were in July of 1863. Unless Abraham Lincoln had a TARDIS, he had no god damn idea about Gettysburg and Vicksburg when he issued the Emancipation Proclamation.

Also, all of those people should read Battle Cry of Freedom by James McPherson. It is, of course, in there. As well as a lot of other good stuff.
