Three members of our corps in Pervyse had evidence many nights of a spy within our lines. It was part of the routine for a convoy of motor trucks to bring ammunition forward to the trenches. The enemy during the day would get the range of the road over which this train had to pass. Of course, each night the time of ammunition moving was changed in an attempt to foil the German fire. But this was of no avail, for when the train of trucks moved along the road to the trenches a bright flash of light would go up somewhere within our lines, telling the enemy that it was time to fire upon the convoy. Such evidences kept reaching us of German gold at work on the very country we were occupying. Sometimes the money itself. My wife, when stationed by the Belgian trenches at Pervyse, asked the orderly to purchase potatoes, giving him a five-franc piece. He brought back the potatoes and a handful of change that included a French franc, a French copper, a Dutch small coin, a Belgian ten-centime bit, and a German two-mark piece with its imperial eagle. This meant that some one in the ranks or among the refugees was peddling information to the enemy. In early October my wife and I were captured by the Uhlans at Zele. Our Flemish driver, a Ghent man, began expressing his friendliness for them in fluent German. After weeks of that sort of thing we became suspicious of almost every one, so thorough and widespread had been the bribery of certain of the poorer element. The Germans had sowed their seed for years against the day when they would release their troops and have need of traitors scattered through the invaded country. The thoroughness of this bribery differed at different villages. In one burned town of 1500 houses we found approximately 100 houses standing intact, with German script in chalk on their doors; the order of the officer not to burn. This meant the dwellers had been friendly to the enemy in certain instances, and in other instances that they were spies for the Germans. We have the photographs of those chalked houses in safe-keeping, against such time as there is a direct challenge on the facts of German methods. But there has come no challenge of facts--we that have seen have given names, dates and places--only a blanket denial and counter charges of _franc-tireur_ warfare, as carried on by babies in arms, white-haired grandmothers and sick women. In October, 1914, two miles outside Ostend, I was arrested as a spy by the Belgians and marched through the streets in front of a gun in the hands of a very young and very nervous soldier. The Etat Major told me that German officers had been using American passports to enter the Allied lines and learn the numbers and disposition of troops. They had to arrest Americans on sight and find out if they were masqueraders. A little later one of our American ambassadors verified this by saying to me that American passports had been flagrantly abused for German purposes.
