I double checked the link, and it works perfectly well.
"...war exists between the Confederate States and the Government of the United States..."
Of course, I understand that many pro-Confederates like to pretend that act of the Confederate congress was not a "Declaration of War".
If that is your opinion too, then I'd invite you to explain the document's purpose, and in what sense, exactly, it is something other than a formal declaration of war on the United States.
Your reference says nothing about declaration of war, and nothing was said about whether your link worked.
The fact is that your assertion about the ‘declaration of war’ is not factual.
It is obvious that any exchange with you will not provide progress since you are unwilling to acknowledge truth in fact.
Perhaps you find humor in creating fallacy, but that is a fool’s errand.
