"M. le Baron;
"I have been thinking over the route for my return to my country about which you came to speak to me this evening. You propose that I shall travel by Vienna. I run the risk of finding myself detained in that town, if not by the action of the Austrian Government, at least owing to the mobilization which creates great difficulties similar to those existing in Germany as to the movements of trains.
"Under these circumstances I must ask the German Government for a promise made on their honor that the Austrian Government will send me to Switzerland, and that the Swiss Government will not close its frontier either to me or to the persons by whom I am accompanied, as I am told that that frontier has been firmly closed to foreigners.
"I cannot then accept the proposal that you have made to me unless I have the security which I ask for, and unless I am assured that I shall not be detained for some months outside my country.
"Jules Cambon."
In answer to this letter on the next morning, Tuesday the 4th August, Herr von Langwerth gave me in writing an assurance that the Austrian and Swiss authorities had received communications to this effect.
At the same time M. Miladowski, attached to the Consulate at Berlin, as well as other Frenchmen, was arrested in his own house while in bed. M. Miladowski, for whom a diplomatic passport had been requested, was released after four hours.
I was prepared to leave for Vienna when, at a quarter to five, Herr von Langwerth came back to inform me that I would have to leave with the persons accompanying me at 10 o'clock in the evening, but that I should be taken to Denmark. On this new requirement I asked if I should be confined in a fortress supposing I did not comply. Herr von Langwerth simply answered that he would return to receive my answer in half an hour. I did not wish to give the German Government the pretext for saying that I had refused to depart from Germany. I therefore told Herr von Langwerth when he came back that I would submit to the order which had been given to me but "that I protested."
I at once wrote to Herr von Jagow a letter of which the following is a copy:
Berlin, August 4, 1914.
