In May 1863 after Chancellorsville, there was discussion over what should be done about Vicksburg. The prevailing opinion was that Longstreet with the divisions of Hood and Pickett, should be despatched to Mississippi, abandon Vicksburg, and attack Grant. Lee objected, citing the likely misuse of his troops.
But let's say Lee decides to send Longstreet to Mississippi. It seems that by May 1863 it's all over but the shouting, and abandoning the city to save the army is the best option left. Lee could send the First Corps west in early April before Grant's landings, rather than to southen Virginia. Depending on when Longstreet is sent, how much impact could he and his troops have on the efforts to defend Vicksburg?
