The interest roused by the _Appam_ shrank into nothing before the excitement caused by the arrival of the submarine _Deutschland_ on the 8th July, 1916. Apart from those that followed the agreement on the _Arabic_ incident, the few days after the arrival of the _Deutschland_ were the pleasantest I experienced in America during the war. Feeling on all sides was openly friendly, and Captain König was the most popular man in the United States. If we had sent ten such merchant submarines to America and for the rest had carried on the submarine campaign according to the principles laid down for cruiser warfare, we should have attained far greater political results than has been the case.
The arrival of the submarine _Deutschland_ at Baltimore and Captain König's first visit to the town resembled a triumphal procession. I had intended to go there at once to welcome the hero of the day and his bold seamen, but thought it better to wait and see what would be the American attitude towards the protests of the English and French Ambassadors, who had both claimed that the _Deutschland_, as a submarine, should be regarded without hesitation as a ship of war. On the 13th July a most minute inspection of the _Deutschland_ was made by an American Government Commission consisting of three naval officers, and she was recognized as a genuine merchant vessel. In consequence the _Deutschland_ had a right to lie at Baltimore as long as was necessary to take a cargo on board for the return journey. It was now possible for me to pay an official visit to Baltimore and to view the _Deutschland_. The Mayor of the town accompanied me and went down with me, in spite of the terrific heat of about 40° centigrade, into the lowest parts of the submarine, which cost the stoutly-built gentleman considerable effort and a good deal of perspiration. In the evening the Mayor gave a banquet which passed off as in the good days before the war. The rooms were decorated with German and American flags, the band played the "Wacht am Rhein," and many speeches were made on the good relations between the two countries.
Again on her second visit, which took place in October in New London (Connecticut), the _Deutschland_ met with a very friendly reception, even though the atmosphere was appreciably cooler. Feeling in the New England state has always been particularly unfavorable to us. But there, to, I passed a very pleasant day with Captain König.
