Toward the end of March, 1915, a distinct change became noticeable in the policy of the German military authorities, and for the first time the people of Roubaix began to feel the iron heel. The allied Governments had formally declared their intention of blockading Germany and the German Army had been given a sharp lesson at Neuve Chapelle. Whether these two events had anything to do with the change, or whether it was merely a coincidence, I do not know; the fact remains that our German governors who had hitherto treated us with tolerable leniency chose about this time to initiate a regime of stringent regulation and repression. [Sidenote: Identification papers.] The first sign of the new policy was the issue of posters calling on all men, women, and children over the age of 14 to go to the Town Hall and take out identification papers, while all men between 17 and 50 were required also to obtain a control card. Up to this time I had escaped any interference from the Germans, perhaps because I scarcely ventured into the streets for the first two months of the German occupation, and possibly also because, from a previous long residence in Roubaix, I spoke French fluently. Strangely enough, though I went to the Town Hall with the rest and supplied true particulars of my age and nationality, papers were issued to me as a matter of course, and never during the whole two years and more of my presence in their midst did the enemy molest me in any way. [Sidenote: Control cards for men of military age.] The only incident which throws any light on this curious immunity occurred about the middle of 1915. Like all other men of military age, I was required to present myself once a month at a public hall, in order to have my control card, which was divided into squares for the months of the year, marked in the proper space with an official stamp "Kontrol, July," or "August," or whatever the month might be. We were summoned for this process by groups, first those from 17 to 25, then those from 25 to 35, and so on. Hundreds of young fellows would gather in a room, and one by one, as their names were called, would take their cards to be stamped by a noncommissioned officer sitting at a table on the far side of the room. On the occasion I have in mind, the noncommissioned officer said to me, "You are French, aren't you?" I answered, "No." "Are you Belgian?" "No," again. "You are Dutch, then?" A third time I replied "No." At this stage an officer who had been sauntering up and down the room smoking a cigarette came to the table, took up my card, and turning to the man behind the table, remarked, "It's all right. He's an American." I did not trouble to enlighten him. That is probably why I enjoyed comparative liberty. [Sidenote: The German policy of enslavement.]
