McIntire, Dennis P. Lee at Chattanooga: A Novel of What Might Have Been
Divergence: 1863 CE
What if: Due to the dissension among Bragg's generals following Chickamauga, Jefferson Davis convinced Robert E. Lee to travel to Chattanooga and offer advice, but not take command.
Summary: Lee suggests an attack plan to force the Union army out of Chattanooga but it's implementation is coincident with Grant's plans for a Union break out. Early Confederate gains are ultimately spoiled by Bragg's predictable failure to exploit success.
