4. Fairchild temporarily commanded the 2nd Division in conjunction with his own 3rd Brigade when Heckman commanded the corps(Eicher p. 230) though Colonel James Anderson may have assumed brigade command until his death (Sommers p. 575). Some reports say Colonel James Jourdan was in temporary command of the division by order of General Heckman (Sommers p.575)
