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 inexhaustible 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. During the afternoon I received your further telegram of the same date,[2] and, in compliance with the instructions therein contained, I again proceeded to the Imperial Foreign Office, and informed the Secretary of State that unless the Imperial Government could give the assurance by twelve o'clock that night that they would proceed no further with their violation of the Belgian frontier and stop their advance, I had been instructed to demand my passports and inform the Imperial Government that his Majesty's Government would have to take all steps in their power to uphold the neutrality of Belgium and the observance of a treaty to which Germany was as much a party as themselves. Herr von Jagow replied that to his great regret he could give no other answer than that which he had given me earlier in the day, namely, that the safety of the Empire rendered it absolutely necessary that the Imperial troops should advance through Belgium. I gave his Excellency a written summary of your telegram, and, pointing out that you had mentioned twelve o'clock as the time when his Majesty's Government would expect an answer, asked him whether, in view of the terrible consequence which would necessarily ensue, it were not possible even at the last moment that their answer should be reconsidered. He replied that if the time given were even twenty-four hours or more, his answer must be the same. I said that in that case I should have to demand my passports. This interview took place at about seven 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.
