Having been dismissed by his colonel, Dudley was questioned and congratulated by Captain Manners, the adjutant, who also expressed regret that the so-called MacGregor had contrived to escape capture.

The members of the "Lone Star Crush" were boisterously warm in their congratulations, chaffing the subaltern as well as they knew; but Wilmshurst, alive to the mannerisms of his brother-officers, took their facetious remarks in good part.

The two officer-airmen added their thanks and good wishes. They were still too weak to walk any distance and had to be carried in roughly-constructed "dhoolies" by the Haussas. Their relief on learning that the seaplane was safely alongside the river was great, especially when they were promised that the work of repairing the floats would be put in hand forthwith.

"Your C.O. evidently wants to get rid of us," declared the pilot smiling. "A crippled 'bus hampers the mobility of the column. We heard that a runner came in just now before we left Gwelba, with the news that an ammunition column and details are on their way up-country.

We've sent down for more petrol, so things look rosy--thanks princ.i.p.ally to you."

"That's nothing," expostulated Wilmshurst. "Merely returning good for evil--that's all."

"'Returning good for evil,'" repeated the pilot. "I don't understand you."

"Let me explain," continued Dudley, laughing at the thought of disillusioning the airmen. "A day or two ago my platoon were posted on the M'ganga road. We were just settling down nicely to give Fritz a warm welcome when you two fellows started dropping bombs on us."

"Good heavens!" e.j.a.c.u.l.a.t.ed the observer. "We thought we were strafing a mob of Huns. No damage, I trust?"

"You would have heard of it before now if there had been," replied Wilmshurst. "The nearest one just dusted some of my men, that's all.

We couldn't get you to see that we were a Haussa platoon, and I had a nice old job keeping my men in hand. They wanted to take pot shots at you. By the bye, what made you chuck it--clear out after dropping only a few bombs?"

"Our last, fortunately for you," said the pilot. "I say, what a frost!

An' we claimed four direct hits, didn't we?"

"We did," corroborated the other dourly. "We seriously considered the idea of giving you a couple of trays of Lewis gun ammunition, Mr.

Wilmshurst. You'd be surprised how difficult it is to distinguish between British and German native troops from any height. By the bye, did you find a mahogany box in the fuselage? Good! it contains undeveloped photograph plates. One we took of your position. I'll send along a print when we get back to our base. It will interest you."

The Waffs were to remain in camp for three days, pending the arrival of the convoy. Even had the latter not been expected the Haussas were temporarily rendered immobile by the presence of the crippled seaplane and her crew, and also by the number of prisoners. The captive Askaris were subjected to a strict examination, with the result that it was discovered that Robert MacGregor was really a German, and a person of some official capacity, since he was on friendly terms with the Hun commandant, while an Askari sergeant gave the traitor's name with great distinctness, Ulrich von Gobendorff, adding that the German used to have charge of a fortified post at Twashi in the Narewenda Hills.

"That's not so very many miles from the Rhodesian border," thought Wilmshurst, as he made a note of the name in his pocket-book. "I wonder if we are ever likely to operate in that district?"

Other information given by the prisoners fixed the position of a German entrenched post held by three native regiments and a handful of whites, at M'ganga, under the command of von Lindenfelt.

"M'ganga? I thought this was M'ganga," exclaimed the puzzled adjutant, referring to a map. "Ask the prisoner how far he marched and in what direction before he was captured?"

The man having replied, Captain Manners was able to locate the spot.

On the German-inspired maps it was shown as a place, whereas, according to the Askari's description M'ganga was a fairly extensive table-land, precipitous on three sides, while on the fourth the ground descended in a series of slight terraces to a broad but shallow river, fordable at a dozen places, within a distance of a couple of miles.

"If only the beggars will stand," exclaimed Colonel Quarrier, "the place will be well worth going for. With our small force a turning movement seems rather a tall order. Of course, if we can get in touch with the Pathan regiments at Kilmoro--and there's a detachment of Rhodesian Light Horse, too, I believe."

"Yes, sir," agreed the senior major. "If we can co-operate--cannot we send a runner, sir? He'll be back before the ammunition and a supply column comes in."

In quick time the repairs to the seaplane were completed, and the craft moored afloat in a wide expanse of the river. Owing to the difficult country, where an aeroplane fitted with landing-wheels would be at a loss to find a suitable spot to alight, a seaplane stood a better chance, owing to the presence of several wide rivers, and here the Sea Service machines of the Royal Air Force scored over the German aircraft; most of which were already _hors de combat_, and could not be replaced owing to the lack of material and the cutting off of German East Africa from practically all communication without.

On hearing of the proposed attack upon von Lindenfelt the naval airmen, who were rapidly recovering from the effect of their arduous and perilous trek, volunteered to remain and co-operate. For observation purposes and machine-gunning the Huns they would be able to render yeoman service, while, when their offer was promptly accepted, the ingenious officers set to work to manufacture bombs.

These missiles, rough and ready in construction, were none the less formidable, while the moral effect was a great consideration. The "eggs" consisted of small sacks filled with cordite, both loose and in cartridges, while by manipulating the fuses of Mills bombs, so that the period between release and explosion was increased to six seconds, the improvised missiles were made to detonate just before reaching the ground after a fall of six hundred feet.

The tempestuous shouts of the Haussas announced the arrival of the transport column, for food was beginning to run short and the men's rations would have had to have been reduced had not the expected stores been speedily forthcoming. There was petrol, too, enough for a series of flights over a distance of two hundred miles; while to the intense satisfaction of officers and men big Jock Spofforth rejoined the regiment, looking none the worse for his encounter with the lioness, except for the still raw scars on his brawny arms.

"Just in time for a dust-up, I find, old man," was his reply to Wilmshurst's greeting. "You've been lucky already, I hear? Where's that MacGregor chap? Is he still with the battalion?"

Briefly Dudley explained what had happened.

"Skunk," muttered Spofforth. "So we've been taking a dirty Hun under our wing, so to speak. I don't mind admitting now that I didn't think much of the blighter when he pushed off and promptly fainted."

"But I scooted, too," interrupted Laxdale, "and left you to tackle the lioness."

"I also plead guilty," added Danvers.

"But with this difference," rejoined Spofforth: "you were unarmed and he had a rifle. Ah, well; you fellows have stolen a march on me, and I've a lot of leeway to make up. When do we move against M'ganga?"

"As soon as we are in touch with the Indian crush," replied Danvers.

"It may be tomorrow."

"Hurrah!" exclaimed Spofforth. "Let's hope it will be a decent sc.r.a.p, and that von Gobendorff will be present at the meeting."

CHAPTER XI

THE SNIPER

It was not until thirty-six hours later that the Waffs moved out of camp for the purpose of delivering a surprise attack upon von Lindenfelt's position. From N'gere a strong force of Pathans, accompanied by a mule mountain battery, was marching in a north-easterly direction to cut off, if possible, the Huns' retreat, while the Rhodesian Light Horse was operating between M'ganga and the Karewenda Geberge in order to keep contact with any German troops likely to attempt to reinforce von Lindenfelt's garrison. To still further encompa.s.s the hostile position a force of Belgians was approaching from the westward. Even if these resolute and energetic troops failed to be in for the actual fighting, they would most effectually round up any stragglers, who would otherwise contrive to escape to the hinterland, where strong bands of Huns still maintained guerrilla tactics.

Almost as soon as it was light the seaplane rose from the surface of the river and flew westwards to note the respective dispositions of the other troops operating against M'ganga. In the absence of wireless Colonel Quarrier could receive the airmen's report only by means of a written message dropped from the seaplane, while before the storming troops were in position the airmen would have to return to their temporary base, replenish petrol and then fly off to bomb von Lindenfelt's stronghold.

Progress was slow as far as the Haussas were concerned. Although there were no indications that the Huns expected an attack so promptly they had made certain preparations. The only approach from the south-east was by means of a narrow path through well-wooded and undulating country, and for miles from M'ganga the wily Germans had beset the road with pitfalls and b.o.o.by-traps. There were caltrops by the hundred--sharp-pointed spikes stuck into the ground, their tips cunningly hidden by dead leaves--which were responsible for a few casualties as the Haussas' bare feet came in contact with the barbs.

These devices the blacks countered by means of implements shaped like exaggerated hoes which they pushed in front of them.

Other defensive measures were heavy logs suspended by boughs overhanging the path by means of light but strong wires. An unwary footfall would release a catch which in turn would cause the baulk of timber to crash to the earth. There were old muskets, charged to bursting point with slugs and nails, which were fired by similar devices, while on three occasions fouga.s.ses, or land-mines, were exploded, fortunately without causing casualties. The Haussas, not to be outdone by their Askari foes, had taken the precaution of driving oxen well in front of the advance guard, and although six beasts had been killed by infernal machines, the troops succeeded in crossing the belt of forest with a loss of five men slightly wounded.

"The explosion of those fouga.s.ses has knocked on the head our chances of delivering a surprise attack," remarked the company commander to Wilmshurst. "It will be a frontal attack against a prepared foe.

Let's hope the Huns won't bolt."

"That's the general opinion, sir," replied the subaltern. "The men are simply longing for a sc.r.a.p. Fritz has thrown away one good chance. He might have played Old Harry with us if he had posted a couple of companies in ambush in the forest."

"I wasn't sorry to get clear of the place," admitted the major. "A hundred men might have been lying in wait in those underglades and our flankers wouldn't spot 'em. Hullo, here's the seaplane."

Flying at a comparatively low alt.i.tude the machine approached rapidly "down wind." In the clear atmosphere the concentric red, white, and blue circles that indicated its nationality were visible from a great distance, while presently the features of the observer could be distinguished as he leant over the side of the fuselage.

Presently a small object to which coloured streamers were attached was dropped from the seaplane. Greatly to the curiosity of the blacks, who watched the descending message with undisguised wonderment, the object did not explode on reaching the ground as they fully expected it to do; and it was with an absurd display of caution that Tari Barl and Blue Fly went to receive it.

"The C.O--sharp!" ordered Wilmshurst. "Don't hold the thing like a snake--it won't bite."

Tari Barl departed on his errand, and returned presently, looking very crestfallen.

"What's wrong, Tarry Barrel?" asked the subaltern.

"Colonel him call me one time fool, sah," he reported. "Him tell you come see him all in dashed hurry quick."
