Previous to the fall of 1915 not only the German Government but the German people were charitable to the opinions of neutrals, especially those who happened to be in Germany for business or professional reasons, but, as the anti-American campaign and the cry that America was not neutral by permitting supplies to be shipped to the Allies became more extensive, the public became less charitable. Previously a neutral in Germany could be either pro-German, pro-Ally or neutral. Now, however, it was impossible to be neutral, especially if one were an American, because the very statement that one was an American carried with it the implication that one was anti-German. The American colony itself became divided. There was the pro-American group and the pro-German government group. The former was centred at the American Embassy. The latter was inspired by the German-Americans who had lived in Germany most of their lives and by other sympathetic Americans who came from the United States. Meanwhile there were printed in German newspapers many leading articles and interviews from the American press attacking President Wilson, and any one sympathising with the President, even Ambassador Gerard, became automatically “Deutschfeidlich.”
As the submarine warfare became more and more a critical issue German feeling towards the United States changed. I found that men who were openly professing their friendship for the United States were secretly doing everything within their power to intimidate America. The Government began to feel as if the American factories which were supplying the Allies were as much subject to attack as similar factories in Allied countries.
