I've noticed in the 1863 and Vicksburg scenarios G.W. Smith is commanding a division at Vicksburg. However G.W. Smith had nothing to do with the fighting around Vicksburg. I suspect he was confused with General Martin Luther Smith, who built the fortifications around Vicksburg and commanded a division under Pemberton in the campaign.
Doubt its possible to add new leaders to the game at this stage, but it bothers me a bit and I felt should point it out. Maybe for AACW2?
