As far as the confluence of the Bakhoy and the Bafing, the march of Gallieni was attended by nothing worse than the usual amount of worry and trouble incident to the passage of a small army through a barbarous or semi-barbarous country. Beyond, however, lay the unoccupied and but partially explored country between the Senegal and the Niger. Here the special trials and cares of the expedition commenced. Food was often obtained with difficulty. Their advance was naturally viewed with suspicion by the natives, and much care and tact was required to prevent friction. In spite of all obstructions, however, they gradually pushed south towards their goal, leaving French flags in the hands of the chiefs, and bearing with them treaties placing the latter and their people under the protection of France.
Before the Niger was reached the expedition came near being destroyed by a determined attack made on it by a people called Beleris. The Beleris were successfully repulsed, however, and two days later Bammaku on the Niger was reached, where already the tricolour was found floating--an advance section of the party having succeeded in concluding the customary treaty. By what means the treaty was obtained we are not told, though we do learn that Gallieni’s reception was cold and inhospitable.
It now only remained to get to Sego, to see the Suzerain of the Upper Niger chiefs and kings, and conclude a treaty with him. For this purpose Gallieni crossed the Niger and travelled along the south side of the river. On his arrival in the neighbourhood of the capital, he was stopped, and ordered to remain where he was, till his business was settled. Many weary weeks and months were passed in the attempt to get Amadu, the Sultan of Sego, to sign a treaty, placing his country under a French protectorate. In the end the necessary signature was obtained, and from that moment French rule--on paper--was supreme from the sources of the Niger to Timbuktu.
France, however, was by no means inclined to be satisfied with a merely mental recognition of her authority. With splendid energy and perseverance she pushed forward her forts into the valley of the Bakhoy--the watershed of the two rivers; and finally built herself an abiding habitation on the Niger itself. At the same time a railway was commenced, having for its object the connection of the highest navigable point of the Senegal with Bammaku. At the same time a gunboat was carried over in sections, and put together on the river, as a further symbol of French authority, and a potent instrument to spread its influence.
