About three o'clock he sent forward two Bairo to ascertain the distance of the enemy, and climbed into his crow's-nest in the tree. Suddenly, in the silence of the forest, a shot rang out. "One of my scouts hit, I'm afraid," said Tom to himself. The waiting warriors stood in an attitude of tense expectancy, every man gripping his weapon, and leaning forward in readiness to move in whatever direction he was ordered. Half an hour passed, and then one of the scouts came swiftly down the path, emerging as it were from a curtain of green. Tom, looking at him, saw fear in his face. His eyes were standing out of his head, his features twitching as though pulled by some unseen string; he was shaking like an aspen. "This won't do," thought Tom; "that fellow will scare the rest." He slipped down the tree, and met the man before he had been seen by any of his comrades. Laying a firm hand on his shoulder, he bade him tell his news. The man collapsed in a limp knot on the ground, and with many a spluttering stumble explained that as he and his mate were creeping along in the bush beside the path, a shot had come from who knows where, and his companion had fallen dead beside him.
"How far ahead was this?"
"Master, how should I know when fear came rustling behind me? I ran, master; my feet carried me as on the wind."
"Where are the enemy?"
"In the bush, master, tens upon tens of them. But I saw none of them; no, I saw nothing but the smoke of the fire-stick in the forest. I am very sick, master, and my old father lies sick at home. Will the master let me go and nurse him?"
Tom sternly bade the man climb the tree before him and hide in the foliage. "Good heavens!" he thought, "if they all turn out like this coward!" But he refused to harbour such a thought, remembering their conduct during the siege. He climbed the tree after the man, waited some twenty minutes, and then saw, fifty yards away among the trees, the head of the Arab column coming slowly along the path. The way was led by half a dozen stalwart Arabs armed with rifles, walking warily, looking right and left for signs of the enemy. They passed, and were followed by fifty Manyema armed with rifles and axes; beyond these he could not see. They came cautiously along; they passed down the main path, silently, watchfully, but without throwing out skirmishers. There was a gap of two hundred yards, and then came the main column of Manyema, armed for the most part with spears. They were marching close behind one another, and Tom's plan was to allow them to occupy the mile and a half on the main track between his tree and the stockade, and then to fall upon them while crowded into this narrow tunnel through the forest. He counted fourteen hundred of the Manyema; there was another gap; then, just as the head of the force of turbaned Arabs was emerging into view, armed with rifles and pistols of various make, a shot from the direction of the stockade announced that the obstacle had been discovered. Dropping from his perch, Tom gave the long-awaited signal to his men waiting in ambush, and an irregular fire broke out down the line of men scattered under cover along the parallel track. The musketeers numbered only about two hundred in all, but Tom reckoned on the surprise counting for a good deal, and the puffs of smoke leaping out from the brushwood at various points, with the clash of explosions, and the demoralizing effect of the hand-grenades, impressed the startled Arabs with the idea that a much larger force than their own was opposed to them.
The surprise was complete. Met by a musket-fire and a discharge of spears and arrows from behind the stockade, the Manyema could not advance; on their left flank there was evidently a well-armed force in ambush; on their right was thick forest, in which they could only find shelter by cutting a way. They halted irresolutely, seeking cover wherever they could. Slugs whizzed through the air and slapped against the trees; the firing of bullets was heard as the rifle-armed Manyema fired erratically at their invisible enemy. But after the first shock they pulled themselves together, and soon realized that they possessed better weapons than their adversaries. They began to move forward again towards the stockade, and Tom, passing down the line, saw that it was time to strike home. Ordering his men on the path to stand firm, he hurried to the stockade, upon which the Manyema had not as yet ventured to make a serious attack. He instructed a party of the musketeers to keep up a steady fire so long as there was no danger of hitting their friends; then, placing himself at the head of the remainder, he led them round the left of the position, and, forcing his way through the thinnest part of the scrub, with a cheer charged down upon the Arab column. The Bahima followed him, raising their sonorous battle-cry. This was too much for the already demoralized enemy. Finding themselves attacked both in their front and on their flanks, the Manyema lost heart, and, turning their backs, began to push along the path in full retreat.
This was a signal to the force on the parallel path to re-double their fire; slugs, grenades, spears, and arrows, fell thick and fast; the Manyema quickened their pace, and, with no thought now of attempting to defend themselves, crowded and jostled one another in their eagerness to flee. Back they ran, higgledy-piggledy, into the Arabs, who were hastening in the other direction to join in the fray, ignorant of what had been going on. The two columns thus meeting brought each other to a halt; but the Manyema behind, goaded now to frenzy, pushed on regardless of their comrades, until soon there was a struggling heap obstructing the narrow path. The panic was communicated to the Arabs, who, after firing a few wild shots, some of which found billets in their own men, turned about and led the flight. Now the Bahima, with savage yells, came pouring out of the forest on to the main path. Every yell had a note of triumph, a tone almost of reckless gaiety, as the men pierced and hacked among the panic-stricken foe. The enemy had by this time fairly taken to their heels, bolting along the narrow track like scared rabbits, impeding each other's movements, trampling dead and wounded ruthlessly underfoot. On and on pressed the Bahima, springing across fallen bodies, heedless of their own wounds, carrying the pursuit for miles, until they found themselves checked by a reserve of Arabs strongly posted in a clearing which had been chosen as the camping-place for their baggage and carriers. Tom, who was foremost among his men, now ordered the recall. Some of his more headstrong warriors did not hear or neglected to obey the signal, and fell victims to their own recklessness.
Hurrying back to the stockade, Tom left five hundred men there to dispute the Arab advance, with orders to hold the position as long as possible, but to retire if they were hard pressed. It was now dusk. No further attack was likely until the dawn, and Tom decided to retire five miles along the path to a position he had previously noted as offering great advantages for defence. It was the river he had crossed during his second day's march. Apparently this was fordable only at the one spot, and the steep shelving bank, itself strongly in favour of defenders posted at the top, could be made doubly formidable by means of a stockade. After fording the river on the rocks, the enemy would have to clamber diagonally up the bank by the path Tom's men had cut, as the undergrowth was too thick to allow of an easier path being made under a determined fire. The bank, muddy and slippery at any time of flood, had been rendered doubly difficult by the recent passage of so many men. A few feet beyond its top, therefore, on the level ground, Tom set his men to build a strong stockade across the path, with a total length of some thirty feet, and curved inwards at each end in order to permit of a flanking fire. The large number of active men employed soon felled enough trees for the purpose; they were split into lengths of about six feet, and planted in the ground close to one another, with transverse logs lashed to them with rough rope, and every interstice filled up with earth and rubbish. It was so placed that a defending force could dominate the whole width of the river, and Tom felt pretty sure that one man within the stockade was fully equal to half a dozen without. The advantage of the position was still further increased by the fact that it was out of sight from the opposite bank, for Tom was careful to leave the intervening scrub untouched, so that it formed an opaque screen.
The stockade having been completed in a thoroughly workmanlike manner by the afternoon of the next day, Tom sent orders to the men he had left farther in the forest to retire as rapidly as possible upon this new defensive position, where he intended to make a serious stand. There was always the chance that the Arabs, finding the direct road blocked, would attempt to get through by cutting another path, but Tom hoped that any such move would not escape observation, and that the time consumed in cutting the new path would enable him to fall back and prepare for meeting the attack elsewhere.
