Why is there so little documentation about the battles in the Vosges Alsace and Colmar regions?

May I respectfully suggest the following: US Army in WW 2 The European Theater of Operations Riviera To The Rhine by Jeffrey J. Clarke & Robert R. Smith Wash.,D.C. G.P.O. 1993 and The Seventh US Army Report of Operations France & Germany, 1944-45 Nashville Battery Press 1988 ISBN: 0-89839-124-5 Richard V. Horrell WW 2 Connections.com
