Baroness van Capellen eventually died of blackwater fever, and the remainder of the party only managed with the greatest difficulty to reach Khartum in July, 1864, where further deaths occurred. The geographical results of this expedition were not published in full till 1869, though Miss Tinne’s cousin printed some notes on their expedition at Liverpool in 1864. [Illustration: ON THE JUR RIVER: SUDD BLOCKING THE CHANNEL.] After four years spent in various places in Egypt, Algeria, and Tunis, Miss Tinne started from Tripoli with a very large caravan to proceed to Lake Chad, intending afterwards to journey from Lake Chad to the Upper Nile. Miss Tinne took with her two Dutch sailors to assist in the organisation of her caravan, several Algerian women-servants, and her confidential old Negress, Saadah, who was originally a slave freed by Miss Tinne in the Sudan. The Turkish authorities made no opposition to her journeys, nor do they seem to have been in any way to blame for the catastrophe that occurred. Unfortunately, Miss Tinne, in order to provide for the comfort of her followers as well as for herself, decided to take with her one or more iron tanks filled with water, which were carried by the camels. These tanks attracted much attention when the expedition halted for a time at Murzuk, the capital of Fezzan, where Turkish authority was still maintained. The rumour that they contained treasure in coin which was to accompany this wonderful princess into the heart of Africa spread from the bazaars of Murzuk to the Tawareq of the desert, ever on the lookout to plunder caravans crossing the Sahara. Miss Tinne had taken all reasonable precautions to secure the friendship of the Tawareq on this journey. She had sent messages to Ghat, an important Saharan town, to the chief Ikenukhen, with presents, and requests for guides. The chief replied that he would meet her himself at a water place on the way to Ghat, and send her the guides. These guides apparently concerted measures with the Arab and Tawareq camel-drivers of her expedition, and plans were evidently laid for her murder and the plunder of her goods.
