Wallace would be an appropriate guy to have available by 1862 for the Union Player.
Wallace commanded a division under Grant at Fort Donnelson....after the fall of the fort he was bumped to Major General. At the Battle of Shiloh, Wallace had some problems with confusing orders and getting his troops to the field on time. As a result, he became a bit of a scapegoat, blamed with almost losing the battle for Grant. After this mess, Wallace was transfered to some less high profile assignments. Later, in 1864, Wallace shows up in the eastern theater where his troops were defeated by Jubal Early at the Battle of Monocacy Junction.
3/1/1 seems about right....
