“Well they did appoint an ambassador to Britain and France with plenipotentiary power to agree to a treaty that would have seen the CSA abolish slavery so they were willing to abolish it during the war.”
The did so only in Nov 1864. By that time most of the Western Confederacy was in the hands of the Union Army.
Lee was penned up in Petersburg. 95% of Southern ports were closed to shipping because of the blockade. Parts of the Confederacy was on the verge of starvation.
The offer to end slavery in exchange for recognition was a last ditch desperate effort to save a Confederacy that clearly was losing the war. The British and French Governments saw was it for what it was, an act of desperation brought on by their immanent collapse of the Confederate house of cards.
So you say but the fact remains that they offered to abolish slavery during the war. Oh, and the war was still very much ongoing and hordes of Yankees still got mowed down before it came to an end.
