No, I got that part. That is all I ever heard for my entire life. "The South started the war and lost it."
Never doubted this was true, although when I was in Junior High, I never understood why the Blockade was necessary. I asked the history teacher, "Wasn't this mostly a Land war?" I just assumed they enacted the blockade because they needed to give the Navy something to do to make it believe it was supporting the war effort.
In the last few years I have come to realize the Blockade was absolutely the most significant and crucial part of the war, because the Blockade is what kept the South from trading directly with Europe. The war was started specifically to stop the South from trading directly with Europe.
But no, I had the "South started the war and lost it" drummed into me. I quit believing that when the facts didn't match up with what I had been taught.
