From the waterguard I obtained more definite information regarding the Rossyth base. So much for the topographical knowledge which could only be obtained through personal contact with men who actually knew every inch of the ground. The charts back in Berlin could not give me that exact information. The higher scientific data of the fortifications and the base, I obtained by social intercourse with high placed officials--officers and engineers at Rossyth--whom I entertained at various times. The schooling I had received in the silhouettes presently came in handy. One night my friend, the bridge tender, learned that the fleet was getting up steam. Accordingly, I stood on the bridge that night and waited. At five o'clock in the morning a gray, rainy, foggy morning, through which the ships moved almost ghost-like, I made out sixteen war vessels. From their silhouettes, I knew them to be dreadnaughts, cruisers, and torpedo boat destroyers. At once I filed a cable by way of Brussels, informing the Intelligence Department of the German Navy that an English fleet sixteen strong had put to sea. Subsequently I learned that in describing the sixteen ships I had made only one mistake. I may here draw attention and in return for England's fair treatment of me during my trial, give them gratis, this information. _The Firth of Forth Bridge constitutes a grave danger to the Rossyth Royal naval base._ For this reason: Its location between Rossyth and the sea is a decided menace. In the event of hostilities, in fact before the outbreak of war, it is no ways impossible to blow up the Firth of Forth Bridge and bottle all war vessels concentrated at the Rossyth base. They could thus be bottled up for several days powerless, while a foreign fleet swept at the Scottish coasts. The British foreign office will understand what I mean by this: _Look to the middle island._ I found it to be partly intervened with soft, soapy neiss, making natural ruts and cavities that were ideal for the placing of explosives. I learned also that along the Edinburgh approach to the Firth of Forth Bridge were two pieces of ground and houses in reality owned by Germans although the deeds stood in Scottish names. Moreover, little fishing hamlets on either side of the bridge harbored more than one supposed Swedish fisherman but who in reality had his name still on the German Naval register. In the event of trouble these men, using explosives stored in the two houses in question, could have blown the Middle Island to atoms. After about three weeks I began to be suspicious of being followed. Arriving home one night I noticed that my dress suit was arranged in a different way to what I had left it. I called my landlady and casually inquired if my tailor had been there. She said, "No, Doctor." "Well," I replied. "What reason have you then to rearrange my clothes?" Her face reddened and she seemed flustered.
