Circling back to this because I've finished it, and while most of it is simply a broad narrative of the war, there are some very good sections on the moral failures of the German general officers. I recently read the German Official Histories of the same period, and think that places too much blame on Hitler for the defeats in 1944-45, while Citino's book returns again and again to the basic math--the Germans might look good plugging a hole but the dikes could never hold and they had no strategic answers from 1943 onward. While Hitler's stand fast orders were bad, most of them made little difference one way or the other as the army wasn't capable of large mobile operations anymore.The last two (dealing with 1943 and 1944-1945 respectively) are really beating a dead horse, IMO.
It seems like OBJECTIVE SCHMIDT from Bounding Fire Productions would be right up your alley."The Battle of the Huertgen Forest" by Charles B MacDonald.
If anyone has read his, "Company Commander", or his tome on the Ardennes offensive, "A Time for Trumpets", they should enjoy this small book. It's a bit dated but it covers the high/low points. One reason for the read is to gather more information the US 28th Infantry Division. The fighting at Kommerscheidt and Vossenack in the forest and in front of Bastogne (the village defences, Clervaux and Wiltz) would make good material for a number of ASL scenarios (in addition to those already in print).
