Movements on turns 1-2 of the previous (November 1862) game:
Key points shown here:
Union movements preparatory to crossing the Rappahannock and the Hazel.
Formation of a battalion-carre structure, with the Union having a "rightward" wing (9th Corps plus Whipple) facing the Valley, plus a central column (1st, 2nd) and a leftward column (5th, 3rd) and 6th in reserve. (Ironically 9th is the core of the Left and 5th is the core of the Right.)
The Confederates have a front line established, but it is very weak along the right flank (Pickett and Kemper have only a few thousand men each). It probably would have been better to move McLaws and Pickett to each cover one of the fords, with Robertson and Ransom setting up in Culpeper along with Pendleton; orders to withdraw if imperilled and each of the individual "delaying" divisions being a strong unit would mean the Union had to "waste time" setting up flanking attacks or going to the further fords.
Anderson's position is much better. Not only is Anderson's division a unitary division which has been kept together (and is thus a very strong single unit) but it's also at a point where Union troops can't work around the immediate flanks in the forest. If Anderson had been deployed forward to the fords it could have been encircled.
The Union right flank is, at this point, quite weak. 6th Corps is available as a (very strong) reserve if need be, but it's still not ideal - Burns, Sturgis, Getty and Whipple have 18,000 men between them and not very good leadership, while Jackson's corps is ~30,000 strong and has excellent leadership.
The fundamental strategic issue though is that the Union could redivert 2nd and 6th Corps to help 9th + Whipple fend off Jackson and they'd still have ca. 70,000 infantry closing in on Culpeper. This is the kind of situation where the Confederates want to delay but not at the cost of manpower - each Confederate casualty hurts a lot more than a Union one because there's less CS manpower on the board.
