Footnote to May 20.--Returning from Brussels to Aachen, we ran across a batch of British prisoners. It was somewhere in the Dutch province of Limburg, a suburb, I think, of Maastricht. They were herded together in the brick-paved yard of a disused factory. We stopped and went over and talked to them. They were a sad sight. Prisoners always are, especially right after a battle. Some obviously shell-shocked, some wounded, all dead tired. But what impressed me most about them was their physique. They were hollow-chested and skinny and round-shouldered. About a third of them had bad eyes and wore glasses.
