"Excellent, let them be given into Kona's charge," Omar exclaimed, explaining briefly that the Dagomba head-man was now in command of the troops, and then turning to the slave who stood in waiting he ordered that Kona should be fetched immediately, and that the council and principal officers should be at once summoned.

In a few minutes we saw upon the clear night-sky long beams of light, and knew that signals were being flashed from Mo to the furthermost limits of the kingdom, summoning the officers from their various posts to a council of war. Twenty thousand men, with a similar number of savage allies, under a leader who was well acquainted with all the intricacies of the secret way were advancing upon Mo, and the faces of the officers and members of the council became grave when, on arrival at the palace, they heard the astounding news.

That Mo was threatened by a serious calamity was recognized by everyone. The news spread through the city quickly, and throughout the night the streets were agog. Only by swift vigorous defence, by pushing a great force forward night and day to the point of attack, could a catastrophe be averted. This was the unanimous opinion of the Naba's advisers, and ere the sun rose the first detachment of the defending army was already on its way to meet the Arab invaders.

Kouaga evidently meant making a sudden descent upon the mysterious country, and if his force once accomplished the passage through the mountain pass they would then no doubt make a rapid dash towards the capital itself, and would approach it at its only vulnerable point.

If this occurred, then the slaughter must be terrible and the catastrophe complete.


CHAPTER XXXII.

WAR.

Twelve days later I found myself accompanying Kona who, at the head of a great force of over eighteen thousand men, was crossing the treacherous quicksands by the Way of the Thousand Steps. The critical position of Mo had been fully discussed by Omar, his officers and sages, and it had been decided to send, in addition to the force of twenty thousand men to the Hombori Mountains on the northern frontier, a second expedition to travel with all swiftness across the sandy plain and make a dash upon Samory's stronghold at Koussan in the absence of its picked troops.

Within two days after Makhana had brought news of the coming invasion, the whole of the twenty thousand men, with Omar himself at their head, had marched out of the capital on their way to defend the pass. I had expressed a wish to accompany them, but my friend had requested me to go with the expedition to Samory's capital because, having been there in captivity, I could act as guide. To this I made no objection, and bidding farewell to Omar, Goliba and Niaro at the city gate, I had watched them ride away at the head of a brilliant cavalcade, and the same evening at sundown descended the face of the cliff by the long flight of steps, and jumping into the saddle of a horse held ready for me, rode with all haste to catch up Kona who, as leader of our expedition, had already started for the gigantic precipice known as the Gate of Mo.
