Some meals were memorable, though not for the menu. One of his earliest Vietnam food experiences was being in a chow line at a big base camp, when a round came in and landed in the bread, injuring the guy who was serving it. It turned out to have been friendly fire from someone who had been playing around with his grenade launcher.
Feeding soldiers on the battlefield has been a challenge throughout the history of war (which is to say, the history of humans). The outcomes of the American Revolution, the Civil War and the Napoleonic Wars (it was Napoleon Bonaparte who coined the phrase, "an army marches on its stomach"), to name only a few, were all decided in part by which side had better access to provisions.
