re: Stan McChrystal - Good riddance: Americans need to set aside icons like Robert E. Lee...

In reality a lot more could have been accomplished by filling the warehouses of Vicksburg and evacuating the non combatants than ever was at Gettysburg.

Grant never did break into the fortifications there and likely never would have. He could not have stayed there forever himself. Bring in Forrest to harass his supply lines,what there were of them and he could have been defeated there, and history changed.
