The source of the message was a hill many miles to the westward of the track by which Rudenheim had come. Two hours afterwards it was reported that the column had reached that track, but had halted in a glade beside the road; the men had thrown themselves on the ground.

"They're taking a rest after their hilly march," thought Tom. "Or perhaps they intend a night attack."

But a few minutes later another message suggested a different explanation. From the further-most eastern post came word that a smaller party was marching from the direction of Neu Langenburg westward. It was formed mainly of porters, with a number of askaris and two white men. Was it not a fair inference that the junction of the road with the northward track had been appointed as rendezvous for both the columns, and that either the one was before its time or the other was late?

Tom made a rapid mental calculation, congratulating himself on the personal knowledge of the road he had obtained in the course of his round of inspection of the scouting posts. When the second column was sighted (that is, only a few minutes before he heard of it), it must have been nearly thirty miles from the rendezvous. Now, the spot where the first column had halted was not the point on the Neu Langenburg road that was nearest to the nullah. Some ten miles east of it there was a scouting post closer to the nullah by about five miles; but the way to it, though shorter, was much more arduous, and for that reason was not at all likely to be chosen by the Germans as the route to their objective. It seemed to Tom that by a rapid march with a light force he might reach this spot on the road before the eastern column, and, given favourable circ.u.mstances, prevent this column from joining the other. He had a rosy vision of snapping up the stores it was conveying, with the result that the threatened attack on the nullah would be at least delayed, while his own resources would be increased.

There were two risks to be taken into consideration: the first, that the western column might not await the arrival of the eastern before resuming its march to the nullah; the second, that the road between them would be so closely patrolled as to render intervention impossible. The scouts, however, had not reported the pa.s.sing of patrols; and as to the first risk, it seemed unlikely that the officer in command would make any further movement until his force was complete. The prize was great, in Tom's eyes well worth the risk, and after a few minutes' cogitation he determined to "put his fate to the touch."

Choosing forty of his best men to accompany him, with Mwesa and two of M'setu's scouts, and leaving Mirambo in charge at the barricade, he started southward. The route he must follow led over very hilly country, covered in parts with forest, through which it might sometimes be necessary to cleave a way. For this purpose he had ordered some of his men to bring axes and bill-hooks, though he hoped that the scouts, knowing the district thoroughly, would find a practicable track, and so avoid the delays which cutting a path must involve.

It was fortunate that since the great storm the rainfall had been light; otherwise much of the ground would now have become swamp, and put him at a disadvantage compared with the enemy on the well-kept high road. Tom had always been known among his friends as a good "foot-slogger," and, hardened as he now was by constant exercise, he had no difficulty in keeping up with his lithe and limber guides. The party covered the first twelve miles in less than three hours, over a track that ran almost due south from the nullah, and was very little obstructed. Then, however, they came into broken country, with steeper ascents and descents and thicker vegetation, where the pace was necessarily slackened. Once or twice the men had to use their implements, and Tom chafed at the delay; but he let no sign of impatience escape him, and found a few cheery words of praise a potent stimulus to his willing negroes.

Presently they came to a hill-stream flowing southward. An idea struck Tom.

"Does this stream cross the high road?" he asked.

The scouts replied through Mwesa that it did.

"Then is there a bridge?"

He learnt that a bridge spanned the stream some distance east of the post for which he had been making. The stream, which was much swollen after a period of heavy rain, had cut a deep and wide channel, and sometimes rose to within an arm's-length of the bridge. Now, however, the rainfall for some days having been slight, it was likely that the water was two men's height below the trestles of which the bridge was made.

This information caused Tom to change his objective. Instead of continuing along the forest track that led directly to the scouting post, he followed the course of the stream, and in some twenty minutes came in sight of the bridge far below. Calling a halt, he sent one of the men to the scouting post on a hill-top invisible from his present position, to inquire of the man stationed there whether he had seen anything of the enemy's columns, or of patrols. The scout's report being rea.s.suring, Tom led his party down to the road, through the brushwood, rank gra.s.s, and bushy shrubs that lined the bank of the stream.

The ground within twenty yards of the road had evidently been at some time cleared of the taller growing vegetation, no doubt to destroy cover. But the lesser plants had sprung up only the more thickly, furnishing safer cover even than the larger shrubs and trees above.

Tom's first idea had been to have the bridge hacked down. This would have effectually checked the march of the columns along the road, and the stream was here so wide and deep, and its banks so steep, that the enemy could not have crossed it until the bridge had been repaired.

Second thoughts raised an objection to this obvious measure. The column would almost certainly be preceded by an advance guard, who would discover that the bridge was broken and give warning. The main body would halt, and Tom would have no chance of getting possession of the stores without a fight. Ignorant of the strength of the column, he dared not risk exposing his small force of comparatively untrained men in the open. Unless he should see a fair prospect of dealing the enemy a "knock-out blow," he would do much better to keep his men out of sight, and remain content with having prevented the two columns from joining forces and thus delayed their advance on the nullah. But this would be only partial success: something more was wanted for complete satisfaction; and an examination of the bridge suggested to Tom what seemed a better way.

Having first sent a couple of scouts in each direction along the road to guard against surprise, he set three men with axes to cut nearly through two of the piles supporting the bridge, one up, the other down stream, just on the water line. A dozen others he sent a few yards along the stream to weave two long, stout ropes from rushes and creepers. Expert at this work, the natives in the course of an hour or so had completed two serviceable ropes about thirty yards in length. Tom tested them by means of an impromptu tug-of-war; then, the axe-men having long finished their part of the job, he himself attached the ropes to the weakened piles by means of bowlines in the notches and allowed them to sag into the water. At intervals he weighted them with stones in order to keep them below the surface, and carrying the free ends up stream, hid them in the vegetation at the foot of the bank. All these operations near the bridge were carried out by men wading in the water, in order that no tracks on the ground should betray them to the enemy scouts.

Tom had only just completed his preparations when the scouts he had sent eastward came running back with news that the enemy column was in sight.

There were two white officers, and an innumerable company of porters and askaris The negro's inability to estimate number was a constant worry to Tom: anything above ten might be reported as a host.

Withdrawing all his men about fifty yards up stream, and posting them under cover of the rushes, he gave them precise orders as to what they were to do when he blew his whistle. Until then no one was to whisper or make the slightest movement. Each man held his rifle with bayonet ready fixed. When he had proved that all were invisible from the road, Tom found a spot where, concealed himself, he had a clear view of the bridge.

He hoped that the period of waiting would not be long, for stillness and silence taxed the negroes more than anything else he could have demanded of them. Already there were signs of restlessness among them when, about half an hour after they had taken up their positions, he caught sight of two figures some distance away, approaching through the bush at the edge of the cleared s.p.a.ce skirting the road. An urgent whisper reduced the Wahehe to stillness again. The two askaris came on quietly, pausing now and again to peer into the thickets beyond the clearing.

Just before they reached the bridge they stepped into the road, and were joined by two more askaris who had emerged from the bush on the other side. The four men crossed the bridge together, separated at the western end, and pursued their way in couples as before.

A few minutes later four files of askaris followed. At a short interval came a connecting file, and then the main body, which consisted of two parties of askaris marching in fours, with a gang of porters between them. With each party there was a German N.C.O. Tom rapidly estimated that the askaris numbered about sixty in all.

When the first party reached the bridge, they broke step and formed two deep to cross. Tom waited until about twenty had gained the other side, then blew his whistle. The Wahehe sprang to their feet. Ten of them fired a volley at the enemy who were upon the bridge, then charged through the thin scrub upon those who had crossed and, startled by the shots and the cries, had wheeled round at the sharp order of their sergeant. Meanwhile twenty men, with Tom at their head, had dashed straight towards the road in the other direction until they had a clear view of the second party beyond the porters, then halted, fired one volley, and charged with the bayonet. At the same time, two groups of five rushed to the spot where the ends of the ropes lay hidden, seized them and hauled with a will. The nearer pile collapsed; the farther held until all ten men tugged at the same rope. Then it snapped like the other, and the whole central part of the bridge fell with a crash into the stream, carrying with it one or two of the rear files of the askaris.

Surprise is halfway to victory. Even European troops could hardly have avoided confusion, however short-lived, when suddenly beset at close quarters by an unsuspected enemy. The German sergeant who had crossed the bridge hardly had time to bring his men into line before the Wahehe, yelling the war-cry of their tribe, were among them. They were severed from the other party by the broken bridge and the crowd of panic-stricken porters, who flung down their loads and fled helter-skelter into the bush. The sergeant and one or two more stood firm and were cut down; the rest turned and bolted across the road, seeking safety in the woods.

Meanwhile the sergeant in command of the second party, being farther from the bridge, had had a few seconds longer to prepare to meet the attack. Before Tom reached him he had halted his men, formed them up hurriedly, and ordered them to fix bayonets. But the time was all too short. The men were still fumbling when the impetuous Wahehe at Tom's heels had surged from the clearing on to the road. Tom made straight for the sergeant, and thrust at him with his bayonet. The German deftly parried the stroke, but before he could himself take the offensive Tom swung his rifle over and brought the b.u.t.t up swiftly against his opponent's chin. The man fell like a log. His askaris did not await the touch of cold steel. Some flung up their hands, others took to their heels, the yelling Wahehe panting behind them. Tom became alive to the danger of his own men scattering in the pursuit and losing themselves in the forest. With loud blasts of his whistle he sounded the signal for recall. Some of the men obeyed instantly, but many minutes had pa.s.sed before all returned, and the weapons of most of them bore witness to the work they had been doing.

Tom lost no time in taking stock of the situation. A few of the askaris had been killed by rifle-shots, a few by bayonets. About twenty were wounded, twelve so seriously that it was clear they could not be moved.

Rather more than twenty had surrendered. One of the German was killed, the other lay where he had fallen. All the rest of the column were scattered through the bush.

Examining the loads dropped by the porters, Tom found that about half consisted of food, half of small-arm ammunition, both valuable booty. He distributed the bales among the unwounded prisoners and some of his own men, and sent them off at once on the return march to the nullah. For the wounded he could do nothing. He ordered those who were slightly injured to revive the sergeant with a dash of water from the stream, and to render first aid to their helpless comrades, knowing that help would be forthcoming from the western column as soon as fugitives had reported the disaster.

By this time the last of the Wahehe had rejoined, and Tom set off on the return journey, soon overtaking the carriers. He pressed the pace as much as possible, though the risk of being pursued was slight. Late in the afternoon, tired but jubilant, his men marched into the nullah, amid exultant shouts from their fellows who manned the defences and the non-combatants who crowded about them as they conveyed their spoils to the village.

Tom discovered that only three of his men had been slightly wounded.

"Almost a bloodless victory," he said to himself. "What wonderful luck!"

But the negroes, discussing the affair far into the night, did not speak of luck. They talked of "white man's medicine," and a.s.sured one another that their particular white man had better "medicine" than any one else in the world.

CHAPTER XIX--BELEAGUERED

Tom's first business was to examine his spoils of war. Besides a considerable quant.i.ty of maize and other foods intended for the askaris, there was a case containing coffee, condensed milk, tinned fruits, biscuits, and a few bottles of wine--articles which were very welcome additions to his private larder. Still more welcome were the boxes of ammunition. One small case held a couple of dozen metal objects whose use he did not know; but uns.c.r.e.w.i.n.g the top of one of them he saw what he took to be combustible material of some kind, and confirmed his guess with a lighted match. These flares, he thought, might prove very useful in case of a night attack.

A commander's chief preoccupation, perhaps, is to divine the intentions of the enemy. What would the column from Bismarckburg do? Its officers had no doubt learnt within an hour or two what had happened to the eastern column, and it seemed probable that the disaster would have deranged their plans. In the course of the afternoon Tom received a message from the scout who had been stationed on the hill overlooking the enemy's halting place. The man reported that a number of the askaris had climbed the hill on different sides, and he had withdrawn to the next post northward. Tom guessed that the German commander had suspected the presence on the hill of scouts who had given him away, and had wisely determined to get rid of them. The post having been thus abandoned, the enemy's movements could not be known at the nullah until they had come within sight from the next post. That, however, was more than twenty miles away, and Tom expected to receive warning of their approach in ample time to prepare for them. He conjectured that they would make no move until they had replaced the supplies of which they had been deprived.

He was not one to sit with folded hands, idly waiting. Next day, taking advantage of his largely increased stock of ammunition, he spent a good many hours in giving his men rifle practice. Owing to the nature of the position, firing, when the attack came, was likely to be at point blank range, so that it was unnecessary to instruct the ma.s.s of the natives in the mysteries of adjusting sights. But in view of the possibility of having to fall back up the nullah, he gave special instruction in long range firing to a score of the men who had had former experience with firearms.

More than once he had wished for the companionship of a man of his own race. Mirambo was a devoted lieutenant, but consultation with him could only be carried on through Mwesa, and his range of ideas was as limited as the boy's command of English. Tom felt the lack of an equal, a man of like upbringing and education, with whom he might have had those long and intimate talks in which mind reacts on mind with mutual helpfulness.

More than ever he wished it now. An advancing enemy should be hara.s.sed; but Tom dared not leave the nullah himself, and neither Mirambo nor any other native had the cool judgment and the self-control necessary in the commander of even a disciplined force, much more in one who had only half-trained negroes under his leadership. Pitted against well-drilled askaris under capable German officers, the Wahehe would be hopelessly overmatched; they would almost certainly be outflanked and cut off, and Tom could not afford to lose men. Under a white man the risks would not have been so great. But it is idle to long for the impossible, and Tom realised that the only safe course was to keep the men with him. He gave orders to his scouts to fall back upon the nullah when the enemy advanced, but slowly, and noting their progress from point to point.

It was on the third day after the little action at the bridge that his furthermost scout reported the enemy were on the move. They had marched two miles along the track from the spot on which they had encamped beside the Neu Langenburg road. There was a great host of askaris, a great host of porters, and several white men. Some of the porters were dragging a long green bottle on wheels.

A long green bottle on wheels!

Tom felt a sinking at heart. What could this be but a field gun? The hosts of askaris did not dismay him: their numbers were, no doubt, exaggerated by the natives as usual; but he recognized that his barricade of trees would be a poor defence against sh.e.l.l-fire. There was little time to improvise adequate protection; but he set almost the whole of his men to work at once in digging a deep trench a few yards behind the barricade.

At intervals during the rest of the day came further reports of the enemy's progress. Their advance was slow; it was clear that they could not reach the nullah before nightfall, and after their long march they would not make an immediate attack. Leaving a strong guard at the barricade, Tom went to his hut to fortify himself with sleep for what the next day might bring forth. But he found it impossible to rest.

Now that the critical moment was approaching, his mind went over and over the situation. Had he left undone anything that might have been done? What would be the effect of sh.e.l.l-fire on his men--aye, and on himself? What were the enemy's plans? Would they, after battering down his outer defences, make a fierce charge into the nullah, relying on the defenders' demoralisation by the bombardment? Thinking over these and other questions, he felt that he had done all he could: the rest was on the knees of the G.o.ds.

Very early next morning he made a round of inspection, then issued through Mwesa his final orders. At the first sign of hostile action the men were to take up their allotted positions. He warned them that they must expect something worse than rifle bullets; but none were to leave the trenches without permission.

To give notice of the enemy's approach, he had posted scouts on the top of the sides of the nullah. But the first intimation came not from them, but from the enemy himself. About midday there was a dull boom in the south. A few seconds afterwards a sh.e.l.l burst with a shattering explosion on the hill face. A cry of astonishment and fear broke from some of the Wahehe; but Tom, in the centre of the trench with Mwesa at his side, calmed them by asking whether they supposed the sh.e.l.ls would destroy the sides of the nullah. The response was an outburst of mocking laughter. It was a big noise, said the men; but the result had been only the fall of broken branches and fragments of rock. All was well.

The bombardment was continued and maintained steadily throughout the day. Some sh.e.l.ls fell harmlessly on the steep sides of the nullah, others in the stream or among the bushes some distance up, others on the clearing outside. One struck the barricade, scattering boughs and twigs and making a gap; but none entered the trenches, and no man was. .h.i.t. By the end of the day the natives had become indifferent to the bombardment, laughing and joking as they watched the smoke and the splinters which did them no harm. With sunset the sh.e.l.ling ceased, and movement in the lower part of the nullah became once more possible. So far, none of the enemy had been seen, and Tom wondered how the gunners had been able to range with even approximate accuracy on their unseen target. He never knew that Major von Rudenheim had not considered the bearing of a flag of truce inconsistent with the taking of careful measurements, by means of which he had fixed on several spots in the forest whence the nullah might be sh.e.l.led at known ranges.

It seemed to Tom hardly likely that the enemy would attempt a night attack before they had ascertained how much damage their gun had done.

Nevertheless, he kept a large number of men under arms all night, relieving them every four hours. Two of the askaris were selected to light the captured flares and throw them over the barricade if the enemy made a move. In the middle of the night Tom s.n.a.t.c.hed a few hours'

sleep, leaving Mirambo in command; and when, shortly before dawn, on returning to his post, he learnt that no sounds had been heard from beyond the clearing, he felt sure that not even a reconnaissance had been attempted, or it would have been detected by the negroes' sharp ears.

It was a misty, drizzly morning, and the trees at the edge of the forest two hundred yards south of the nullah loomed through the murk only as a blurred ma.s.s. Tom gave orders to his scouts, before they climbed to their watch-posts above, to be specially vigilant. About seven o'clock a sh.e.l.l burst just behind the trench, and three of his men were slightly injured by splinters. The fact that the sh.e.l.l exploded before the boom of the gun was heard, showed that the gunners had drawn nearer during the night. This was the opening of a bombardment that continued for about three hours. Again little damage was done, most of the sh.e.l.ls falling many yards behind the barricade.

Suddenly the firing ceased. The scouts, sharp-eyed though they were, had reported no movement among the trees, when there came the shrill blast of a whistle. Tom had posted himself with his men at the barricade, and he was just able to see, through the mist, a compact line of askaris break from cover. There was no attempt at skirmishing; the enemy rushed straight across the clearing towards the mouth of the nullah. Twenty yards behind them came a second line, and with these Tom saw the white helmet of a German officer.
