One of the commonest problems was the one presented by the officer of German extraction who had been born and bred amid Teutonic influences, and who was naturally pro-German in sympathy and utterances before the United States entered the war, but who had been guilty of no act or utterance since that date which could be construed as in any degree disloyal, and who, from a military point of view, was extremely efficient. Such cases, in the last analysis, always resolved themselves into the question: “Is he fit to go across?” Each case was, of course, considered on its own merits. While it was obviously impossible to lay down a rule-of-thumb applicable to all, two considerations in the main governed the decision. In the first place, an effort was made to obtain the opinions of the officers serving with the man in question and to learn whether they would be satisfied to go into action against German troops with him. If his fellow officers felt that they could trust him under such circumstances, it was a fair judgment in his favor. The second consideration was to ascertain whether his name, lineage, or appearance would make him unacceptable to our French allies. If such were likely to be the case, international courtesy, if nothing else, made it inadvisable to send him overseas. Surveillance of these men naturally was continued in France, but the Intelligence Division of the A. E. F., in reporting that such a case could be considered closed, frequently said in effect that any taint of disloyalty which might once have existed had been burned away by the fire of battle.
