“And now he seeks for those he sent out and who never returned. He asked that he might do it. If you talk to Captain Zinn about it, you know why he made the request. You know how he feels about that which he is doing. There is no mawkish sentiment about Captain Zinn. “But deep down within him Captain Zinn feels that he and no other should go out on the mission that now engages him. He has an interest that is intimate and personal.

Through the torn fields and woods in the Verdun, Château-Thierry, St. Mihiel, and Meuse sectors he has gone. He has tramped through the Argonne to Sedan and sought in the mountains that encircle Metz and hide the valley of the Moselle. Wherever there was fighting in which the American Air Service participated, there has gone, or will go, Zinn. “Out of 150 missing American aviators, Captain Zinn already has definitely located and identified the spots where seventy fell and were buried. It has required many days of painstaking search and inquiry to attain this result. “Captain Zinn has found that in a great many cases American fliers were buried either by the Germans or by civilians with no mark of identification left on them. THE UNIDENTIFIED “Many times he has come upon a grave with a rude cross on which was scrawled: ‘Unidentified American Aviator’ or ‘Two Unidentified American Aviators.’ He has had to obtain positive identification by careful examination of air-service records, questioning of peasants and civilians who saw American machines brought down and deductions based on the information he gathered. In some instances it has been necessary to open graves to make sure. “To start out with, Captain Zinn has the records of squadrons, which show, for instance, on what date a missing pilot went out, what his mission was, over what country he naturally would go, and what kind of machine he had. Perhaps an attack by an overwhelming force or an accident or other circumstances forced the pilot off the course marked out for him. When he failed to return, only speculation as to where he fell could be indulged in. Unless the Germans notified his squadron of his death and the location of his grave, he became one of the men for whom Captain Zinn now seeks.
