In accordance with the instructions contained in your telegram of the 4th instant, I called upon the Secretary of State that afternoon and inquired, in the name of His Majesty's Government, whether the Imperial Government would refrain from violating Belgian neutrality. Herr von Jagow at once replied that he was sorry to say that his answer must be "No," as in consequence of the German troops having crossed the frontier that morning, Belgian neutrality had been already violated. Herr von Jagow again went into the reasons why the Imperial Government had been obliged to take this step, namely, that they had to advance into France by the quickest and easiest way, so as to be able to get well ahead with their operations and endeavor to strike some decisive blow as early as possible. It was a matter of life and death for them, as if they had gone by the more southern route they could not have hoped, in view of the paucity of roads and the strength of the fortresses, to have got through without formidable opposition entailing great loss of time. This loss of time would have meant time gained by the Russians for bringing up their troops to the German frontier. Rapidity of action was the great German asset, while that of Russia was an in exhaustible supply of troops. I pointed out to Herr von Jagow that this fait accompli of the violation of the Belgian frontier rendered, as he would readily understand, the situation exceedingly grave, and I asked him whether there was not still time to draw back and avoid possible consequences, which both he and I would deplore. He replied that, for the reasons he had given me, it was now impossible for them to draw back....
This interview took place at about 7 o'clock. In a short conversation which ensued Herr von Jagow expressed his poignant regret at the crumbling of his entire policy and that of the Chancellor, which had been to make friends with Great Britain, and then, through Great Britain, to get closer to France. I said that this sudden end to my work in Berlin was to me also a matter of deep regret and disappointment, but that he must understand that under the circumstances and in view of our engagements, His Majesty's Government could not possibly have acted otherwise than they had done.
I then said that I should like to go and see the Chancellor [von Bethmann-Hollweg], as it might be, perhaps, the last time I should have an opportunity of seeing him. He begged me to do so. I found the Chancellor very agitated. His Excellency at once began a harangue, which lasted for about twenty minutes. He said that the steps taken by His Majesty's Government was terrible to a degree; just for a word -- "neutrality," a word which in war time had so often been disregarded -- just for a scrap of paper Great Britain was going to make war on a kindred nation who desired nothing better than to be friends with her. All his efforts in that direction had been rendered useless by this last terrible step, and the policy to which, as I knew, he had devoted himself since his accession to office had tumbled down like a house of cards. What we had done was unthinkable; it was like striking a man from behind while he was fighting for his life against two assailants. He held Great Britain responsible for all the terrible events that might happen. I protested strongly against that statement, and said that, in the same way as he and Herr von Jagow wished me to understand that for strategical reasons it was a matter of life and death to Germany to advance through Belgium and violate the latter's neutrality, so I would wish him to understand that it was, so to speak, a matter of "life and death" for the honor of Great Britain that she should keep her solemn engagement to do her utmost to defend Belgium's neutrality if attacked. That solemn compact simply had to be kept, or what confidence could any one have in engagements given by Great Britain in the future? The Chancellor said, "But at what price will that compact have been kept? Has the British Government thought of that?" I hinted; to his Excellency as plainly as I could that fear of consequences could hardly be regarded as an excuse for breaking solemn engagements, but his Excellency was so excited, so evidently overcome by the news of our action, and so little disposed to hear reason that I refrained from adding fuel to the flame by further argument.
