aeroplane appeared a succession of sudden fleecy puffs of smoke, looking soft and harmless as cotton-wool. One of these came just before the nose of the aeroplane. Next moment the machine gave a great swooping dive, righted itself, dived again, and dropped like a stone.
"Thank God for that!" muttered the young lieutenant, and his men cheered grimly under their breath.
Three minutes later the detachment came to an old stone bridge. Here it halted. The men began hastily entrenching themselves where they could best command the approaches on the other side. The machine-gun, lifted from its little carriage, was placed cunningly behind a screen of reeds. The two dogs, panting, lay down in their harness under a thick bush. In an amazingly brief time the whole party was so hidden that no one approaching from the other side of the canal could have guessed there was anything more formidable in the neighbourhood than the ruminating cows.
The neglected, almost forgotten, old bridge had suddenly leapt into importance. Reinforcements for the sore-pressed division to the south-east were being sent around by the north of the canal, and were to cross by the bridge. The detachment had been sent to guard the bridge at all costs from any wide-roving patrols of Uhlans who might take it into their heads to blow it up. In war it is a pretty safe principle to blow up any bridge if you are quite sure you won't be wanting it yourself. The fact that the other side has spared it is enough to damn it off-hand.
The tumult of the far-off gunfire was so unremitting that the ears of the bridge-guard gradually came to accept it as a mere background, against which small, insignificant sounds, if sudden and unexpected, became strangely conspicuous. The crowing of a cock in the farmyard a few fields off, the sharp cry of a moorhen, the spasmodic gabbling of a flock of fat ducks in the canal – these small noises were almost as clearly differentiated as if heard in a stark silence.
For perhaps an hour the detachment had lain concealed, when those ominous pillars of smoke against the sky were joined suddenly by swarms of the little white puffs of cotton-wool, and the confused noises redoubled in violence. The battle was swaying nearer and spreading around a swiftly widening arc of the low horizon. Then another aeroplane – another bird-like Taube – came in view, darting up from a little south of west. The young lieutenant, in his hiding-place beside the bridge-head clapped his glasses anxiously to his eyes. Yes, the deadly flier was heading straight for this position. Evidently the Germans knew of that out-of-the-way bridge, and in their eyes also, for some reason, it had suddenly acquired importance. The Taube was coming to see in what force it was held.
"Spies again!" he grunted savagely, turning to explain to his men.
Flying at a height of only five or six hundred metres, the Taube flew straight over them. There was no longer any use in attempting concealment. The riflemen opened fire upon it furiously as soon as it came within range. It was hit several times; but the Taube is a steel machine, well protected from below, and neither the pilot nor any vital part of the mechanism was damaged. It made haste, however, to climb and swerve away from so hot a neighbourhood. But first, as a message of defiance, it dropped a bomb. The bomb fell sixty or seventy yards away from the bridge back in the meadow, among a group of cows. The explosion killed one cow and wounded several. The survivors, thus rudely shocked out of their indifference, stamped off down the field, tails in air and bellowing frantically.
"That cooks our goose," snapped one of the riflemen concisely.
"Their shells'll be dead on to us in ten minutes' time," growled another. And all cursed soberly.
"I don't think so," said the young lieutenant, after a moment's hesitation. "They want the bridge, so they won't shell it. But you'll see they'll be on to us shortly with their mitrailleuse and half a battalion or so, enough to eat us up. We've got to get word back quick to the General for reinforcements, or the game's up."
"I'll go, my lieutenant," said Jean Ferréol, an eager, dark Walloon, springing to his feet.
The lieutenant did not answer for some moments. He was examining through his glasses a number of mounted figures, scattering over the plains to the rear in groups of two and three. Yes, they were Uhlans unquestionably. The line of combat was shifting eastward.
"No," said he, "you can't go, Jean. You'd never get through. The Bosches are all over the place back there now. And you wouldn't be in time, even if you did get through. I'll send one of the dogs."
He tore a leaf out of his note-book and began scribbling.
"Better send both dogs, my lieutenant," said Jan Steen, the big, broad-built Fleming who had charge of the machine-gun, unharnessing the dogs as he spoke. "Leo's the cleverest, and he'll carry the message right; but he won't have his heart in the job unless you let Dirck go along with him. They're like twins. Moreover, the two together wouldn't excite suspicion like one alone. One alone the Bosches would take for a messenger dog, sure, but two racing over the grass might seem to be just playing."
"Bon!" said the young lieutenant. "Two strings to our bow."
He hurriedly made a duplicate of his dispatch. The papers were folded small and tied under the dogs' collars. Big Jan spoke a few words crisply and decisively in Flemish to Leo, who watched his lips eagerly and wagged his tail as if to show he understood. Then he spoke similarly, but with more emphasis and reiteration, to Dirck, at the same time waving his arm toward the distant group of roofs from which the detachment had come. Dirck looked anxiously at him and whined, and then glanced inquiringly at Leo, to see if he understood what was required of them. He was almost furiously willing, but not so quick to catch an idea as his more lively yoke-fellow. Big Jan repeated his injunctions yet again, with unhurried patience, while his leader fumed behind him. Jan Steen knew well that with a dog, in such circumstances, one must be patient though the skies fall. At last Dirck's grin widened, his tail wagged violently, and his low whining gave way to a bark of elation.
"He's got it," said Jan, with slow satisfaction. He waved his arm, and the two dogs dashed off as if they had been shot out of a gun, keeping close along the inner base of the dyke.
"Dirck's got it," repeated Jan, with conviction, "and nothing will put it out of his head till he's done the job."
Side by side, racing wildly like children just let out from school, the two dogs dashed off through the grass along the base of the dyke. Leo, the lighter in build and in colour, and the more conspicuous by reason of a white fore-leg, was also the lighter in spirits. Glad to be clear of the harness and proud of his errand, he was so ebullient in his gaiety that he could spare time to spring into the air now and again and snap at a low-fluttering butterfly. The more phlegmatic Dirck, on the other hand, was too busy keeping his errand fixed in his mind to waste any interest on butterflies, though he was ready enough to gambol a bit whenever his volatile comrade frolicked into collision with him.
Soon – Leo leading, as usual – they quitted the dyke and started off across the open meadows toward the hottest of the firing. A couple of patrolling Uhlans, some distance off to the right, caught sight of them, and a bullet whined complainingly just over their heads. But the other Uhlan, the one who had not fired, rebuked his companion for wasting ammunition. "Can't you see they're just a couple of puppies larking round?" he asked scornfully. "Suppose you thought they were Red Cross."
"Thought they might be dispatch dogs, Herr Sergeant," answered the trooper deprecatingly.
"Well, they're not, blockhead," grunted the cocksure sergeant. And the two rode on, heading diagonally toward the canal.
The dogs, at the sound of the passing bullet, had crouched flat to the ground. When the sound was not repeated, however, they sprang up and continued their journey, Leo, excited but not terrified, more inclined to frolic than ever, while Dirck, who by some obscure instinct had realized that the shot was not a chance one, but a direct personal attack,
