I doubt if anyone could have stopped Grant. Regardless if Jackson was alive or not, the fact was that the south was out of resources by that time. Jacksons presence may have only delayed the innevitable. I believe that if he had went on to Washington in May of 1861, the war would have been over before it had actually started. Longstreet had a relitivly fresh Brigade at Blackburns ford. There were also fresh regiments at Mitchells and Mcleans fords. Plus I believe that Early, Evans and Holmes all had fresh troops. I dont understand why Davis didn't go for Jacksons plan.
