Under these circumstances, I volunteered cheerfully to accompany Mr. Richardson, on the sole condition, however, that the exploration of Central Africa should be made the principal object of the mission, instead of a secondary one, as had been originally contemplated. In the meantime, while letters were interchanged between Berlin, London, and Paris (where Mr. Richardson at that time resided), my father, whom I had informed of my design, entreated me to desist from my perilous undertaking, with an earnestness which my filial duty did not allow me to resist; and giving way to Dr. Overweg, who in youthful enthusiasm came immediately forward to volunteer, I receded from my engagement. But it was too late, my offer having been officially accepted in London; and I therefore allayed my father’s anxiety, and joined the expedition. It was a generous act of Lord Palmerston, who organized the expedition, to allow two foreign gentlemen to join it instead of one. A sailor was besides attached to it; and a boat was also provided, in order to give full scope to the object of exploration. The choice of the sailor was unfortunate, and Mr. Richardson thought it best to send him back from Múrzuk; but the boat, which was carried throughout the difficult and circuitous road by Múrzuk, Ghát, Aïr, and Zínder, exciting the wonder and astonishment of all the tribes in the interior, ultimately reached its destination, though the director of the expedition himself had in the meanwhile unfortunately succumbed. Government also allowed us to take out arms. At first it had been thought that the expedition ought to go unarmed, inasmuch as Mr. Richardson had made his first journey to Ghát without arms. But on that occasion he had gone as a private individual, without instruments, without presents, without anything; and we were to unite with the character of an expedition that of a mission,—that is to say, we were to explore the country while endeavouring at the same time to establish friendship with the chiefs and rulers of the different territories. It may be taken for granted that we should never have crossed the frontier of Aïr had we been unarmed; and when I entered upon my journey alone, it would have been impossible for me to proceed without arms through countries which are in a constant state of war, where no chief or ruler can protect a traveller except with a large escort, which is sure to run away as soon as there is any real danger.
