NORMANDY BEACHHEAD, June 17, 1944 — In the preceding column we told about the D-day wreckage among our machines of war that were expended in taking one of the Normandy beaches.But there is another and more human litter.

This is the strewn personal gear, gear that will never be needed again, of those who fought and died to give us our entrance into Europe.
