The Deserters: A Hidden History of WWII by Charles Glass

This is a terrific book on topic rarely covered in WW2 histories. It uses the stories of three men–two American and one British–as a lens to examine desertion and a host of related topics: battle fatigue, military justice, battlefield psychology, and leadership. It also highlights how truly terrible the American system was for combat infantrymen and their replacements. Basically, the Americans put the burden of the fighting on a relatively small number of divisions. Whereas other counties (and America in other wars) would rotate units off the front line to recuperate and incorporate replacements, the US army had a system that put replacement soldiers into a general pool and then assigned them to units on an ad hoc basis while the units were still in combat. Instead of going into battle with a group of men they knew and had trained with, the replacements were dumped into units where they knew no one. Many were killed within days of arriving, sometimes before their new officers even learned their names. It is no surprise that veterans reached a breaking point after too many consecutive days in combat, and that replacements deserted after being cast adrift with no support network. If you are interested in WW2 at all, I totally recommend The Deserters.
