Jackson, shortly before his wounding, had been hoping to get between the Army of the Potomac and the fords of the Rapphannock, specifically United States Ford, and had instructed his senior division commander AP Hill to prepare a night attack to accomplish that end. Jackson was not specifically instructed to attempt this, but it was very much in line with Lee and Jackson's hopes of achieving the destruction of the Army of the Potomac in the field. But such hopes were shot down with Jackson, for AP Hill too was struck down by friendly fire in the woods near the Orange Turnpike, though non-fatally, and this fundamentally changed the plan. Hill was the only one who had any idea what Jackson was planning, as Jackson was notoriously secretive with his subordinates.
If Jackson had not been shot, A.P. Hill’s ‘Light’ Division would attempted to seize the U.S. Ford through a night attack. A night attack, in addition to the inherent difficulties of such, would have brought Jackson up against fresh Union troops and would have been highly unlikely to achieve his hopes for it. The III Corps still occupied Hazel Grove with 34 guns posted, and the divisions of Berry (III Corps), Alpheus Williams (XII Corps), a supporting brigade from the II Corps and a mix of willing men from XI Corps were already in position to face any attack from A.P. Hill. In addition, 37 guns had been posted at Fairview under Captain Best.
By then, Jackson’s flank attack had already sputtered out. The 30,000 man Corps had been completely disorganized due to Jackson’s faulty deployment of the line and the fighting with the XI Corps. Only A.P. Hill’s division was in any state to continue the attack to U.S. Ford. If May 3rd is anything to go by, A.P. Hill’s attack would be repelled and the Confederates would be in an even worse position than OTL and rely on Mr F.J. Hooker to bail themselves out as historical.
