As most of us already know, in the year 1863, Braxton Bragg won a huge victory at the battle of Chickamauga. Afterwards, the Union Army of the Cumberland hastily retreated to Chattanooga which then became under siege.
Personally, I feel that the Union victory at Chattanooga was the true turning point in the war. It opened up the deep south to the Union army and the victory sent General Grant east to fight Lee.
Now the question is, could the Confederates have won the siege of Chattanooga? Could they have starved the entire Army of the Cumberland and forced them to surrender? If they could and did, could it be argued that Grant is never sent east, the South re invades Tennessee, and Lincoln loses the 1864 elections?
I'm perfectly willing to admit that I am not the greatest expert on the Civil War on this forum (waiting for a certain Smith to destroy this post

). However, in my opinion the siege of Chattanooga is the best chance for the South to either make peace or at least delay the inevitable.
Another question. If a Southern Victory at Chattanooga doesn't do much to help the South, would a even bigger victory at Chickamauga do a better job at helping?
