The section of the jail in which we were confined was under the primary management of the Kommandantur of Berlin. The Kommandantur was represented at the jail by an officer who remained there during the whole period of my incarceration. His name was Lober Lieutenant Block. Under that officer was a sergeant-major, and under the sergeant-major were seven non-commissioned officers and a doorkeeper, ranking as a non-commissioned officer. Two of the non-commissioned officers occupied an office on the ground floor. The others were assigned to duty on the several floors where they acted as inspectors or watchmen. The sergeant-major was responsible for the general superintendence of the jail and he made an inspection every day. As to the head officer his dignity was such that he would not condescend to pass through the corridors more than two or three times a week. A mania which appears to be general among German officers and non-commissioned officers alike is to be both loud and violent every time they speak to subordinates or prisoners. Not a single day would pass without the walls ringing with the echoes of the cries and threats these men uttered to certain prisoners. The poor Poles! What invective and abuse they had to endure! I mention the Poles specially because from Poland there passed during my three years of captivity to the prison of the Stadtvogtei a greater number of prisoners than from any other place. Of two hundred and fifty prisoners quite two-thirds were of Polish origin. The other prisoners included English, French, Italians, Russians, Portuguese; in fact, all the nations at war with Germany were represented. At times there were Arabs, Hindoos, African negroes, Japanese, and Chinese. What may surprise the reader is the fact that the four central powers themselves–Germany, Austria, Bulgaria, and Turkey–held constantly some of their own subjects in this prison. Germany never had less than from five to ten of her subjects in the jail. They were mostly political prisoners who were reputed to be a menace to the security of the German empire. I shall have occasion later on to speak about two prisoners, in particular, Socialist members of the Reichstag. But more than Germany and her allies and the countries with whom they were at war were represented in this prison. At different times, prisoners belonging to the neutral nations of Europe–Norway, Sweden, Denmark, Holland, Switzerland, and Spain–were guests at the Stadtvogtei.
