Behind the stockade the defenders were keenly alert; Barega had command of the north-western section, and the katikiro, who, genial time-server as he was in peace, was a very paladin in war, commanded on the south-west. Seeing that all along the western boundary the defence was in good hands, Tom hastened to the south-east to assure himself that no danger need be feared in that direction. Barely half a minute after he reached a smithy in the south-eastern corner, from the yard of which he could scan the whole country to the horizon, he saw a strong body of men spring out of the banana plantation he had vainly urged Barega to cut down. They, like their fellows on the other side, had with them a long piece of trellis-work. Evidently there was not a moment to lose. Tom despatched Mbutu to inform Barega of the danger; but so quickly did the enemy move, that in less than two minutes they had arrived at the edge of the ditch, flung the trellis bridge across, and begun to swarm over to the other side, nimbly evading the planted stakes.
Tom looked around. Only some ten men were within call. Summoning these to his assistance, he turned to defend the stockade. He had no weapon but the musket got in the forest, and that, in default of ammunition, he could only use as a club. By the side of the smith's rude anvil he saw a recently-sharpened sickle, with a handle eighteen inches long. This he seized, and sprang to his post again. Some twenty of the enemy, he saw, bore light scaling-ladders, hastily constructed since the previous fight. These they placed against the stockade and began to clamber up. There was a fierce hand-to-hand fight. Tom caught hold of the top of one of the ladders, on which two Arabs were ascending, and putting forth his utmost strength, flung it back so that it fell on the climbers. Some of the Bahima were thrusting their spears through interstices in the stockade, and cries of agony bore witness to their success. But for every man that fell another sprang up to take his place. Already several of the enemy had reached the tops of their ladders, and were firing, fortunately with erratic aim, at the panting defenders. Three, indeed, had clambered down on the inner side, and still there was no sign of the expected reinforcements. Tom had been slashing with his sickle in his right hand, and warding off with the musket in his left the blows of Arab swords and Manyema spears. Seeing three of the enemy within his lines, he was down in a moment at the foot of the stockade. One of the three he clubbed with his musket, and then, while Mbutu, who returned at this moment, fiercely engaged the second, he pressed hotly upon the third. Two of the Bahima were prostrate; the remaining eight were vainly attempting to stem the torrent now pouring over the palisade, and Tom was in the thick of the mêlée, laying about him doughtily. It was a tense moment; Tom and his little band were outnumbered ten to one; and the fate of the village hung in the balance. The enemy were creeping up behind for a final rush, when the katikiro charged down at the head of two hundred yelling Bairo. The stockade was cleared in a few seconds and the baffled enemy driven back over the ditch.
"Whew!" blew Tom, and then for the first time became aware that he had received a slight spear-wound in the right arm. "Blood-brother indeed!" he said with a smile to the katikiro. "But Msala, my friend, you were only just in time. In a minute or two it would have been another case of what-d'ye-call-him against the world. Why were you so long bringing up reinforcements?"
The katikiro was exceedingly sorry, but just before Mbutu had reached him a similar request had been made by the chief, and he had felt bound, of course, to obey his chief first. But it turned out after all to be a mere waste of time, for the enemy in the north-west quarter, while making an extremely blusterous demonstration, had never come within striking distance, and Msala had soon recognized that their show of activity was a mere feint to draw off attention from the real attack at the other end. Tom saw that the delay had been unavoidable, and could only be thankful that the much-needed support had come after all in the very nick of time.
The brief rest was a boon; but the enemy were not routed, nor even definitively driven off. They were still clinging to their position outside the stockade, and the Bahima could not get at them without exposing themselves, nor even assail them effectively with their spears, for the Arabs had rifles, and were indeed dropping shots over into the village. It was clearly necessary to put a stop to these offensive tactics, and Tom was perplexed as to what measure to adopt. Suddenly the idea occurred to him: could he try a few fireballs? Vague recollections came to him of something he had read about fireballs in defence of towns during the wars in the Netherlands. He had noticed plenty of coarse wool of sheep and goats in the village; there were heaps of shavings where the artificers had been making spear-shafts; and the place was reeking with fat of various kinds. He knew also that there was a large store of the native spirituous liquors, museru and marwa, in a shed near the hut of the chief's cook and purveyor, the muchumbi wanyama, and he thought it would be rather a good than an evil if some of the spirits were consumed externally. He therefore left the katikiro in command while he himself went to consult the chief.
Barega was charmed with the simplicity and ingenuity of the notion of worrying the enemy with fireballs, but somewhat downcast when he learnt the use to which his wine-cellar was to be put. Thereupon Tom, with the tact that had marked all his dealing with the natives, did not insist, but quietly pointed out that if the Arabs got in, they would set fire to the village, and the spirits would be destroyed with all the rest. It was surely better to use half of it in doing some mischief among the enemy, and perhaps by this means decisively turn the scale.
The chief thought over the matter, consulted the kasegara, and finally, with an obvious wrench, gave his consent to the course Kuboko proposed. No more time was lost; twenty natives were immediately set to roll up balls about six inches in diameter, made of wool and shavings and fat, and anything else combustible that came to hand, and finally steeped in the heady spirit. When some hundred balls were ready, Tom had them carried to his old post, where the Arabs were once more attempting to scale the stockade. They were lighted and thrown in rapid succession over the stockade on to the trellis-bridge. The Arabs at first tried to quench the fallen balls, but others came flaming through the air still more rapidly, and after some score had been thrown, fearing that their retreat over the ditch was likely to be cut off by the burning of their bridge, the enemy threw up the sponge and beat a hasty retreat. As they retired, the Bahima gave a tremendous whoop, and sent a cloud of arrows and spears after them, causing many a gap in their ranks. They fled on in rage and confusion, and vanished behind the plantation.
"Ah! I think they've had enough," said Tom. "Barega, my brother, what do you think of our morning's work?"
Barega confessed himself "pleased too much", as Mbutu interpreted him. "Say one fing, sah; say no want no more museru wasted!"
"Good heavens!" was Tom's thought, "it's all got to be argued again. Wasted! As Mr. Barkworth would say, 'There's no gratitude in these natives!'" But all he said was: "Tell the chief that I hope we shall need no more of his excellent stuff, and that I consider he has shown a fine spirit of self-denial for the common good. The scamp!" he added under his breath; "he ought to be as pleased as Punch!"
