"After they separate we"d better lie low a while," suggested Rob.
"What for?" demanded Tubby, bound to understand everything, even if he had to swamp his mates with questions.
"The spy, or spies, for there may be more than one of them, might just happen to cross this way, so as to get to the road; and, if they saw three shadowy figures moving along, the first thing they"d be apt to think was that we were enemies who had been listening."
"Oh! now I see!" Tubby admitted. "And, since we don"t want to be made targets for them to practice at, we"ll be wise to do what you say, Rob."
"Please, please, let up on all that talk, Tubby!" implored Merritt.
"Oh! I will, if it bothers you any," the fat boy answered; "but I think it queer a fellow can"t ask a few little innocent questions once in a while, without being sat down on so hard. Now, I know a boy who made himself a real nuisance with his everlasting wanting-to-know, but I only speak up when there"s absolute nec----"
Tubby stopped short there. It was not that the annoyed Merritt clasped a hand over his mouth, thus shutting off his supply of breath, for no such thought entered the mind of the corporal of the Eagle Patrol; but just then a horrible din, in which shots, mingled with wild shouts, broke out in the field nearby.
CHAPTER XIII.
CAUGHT IN THE ACT.
What had happened was no mystery to Rob and Merritt, though possibly Tubby, not quite so apt to jump to conclusions, remained a little bewildered at what was going on.
It seemed that the Belgians must have suspected something wrong, and possibly followed the bearer of the lantern when he went into the open field to flash his signals toward the sky.
The three scouts from across the ocean were not the only watchers who had read that message. Yes, and the coast had not been as clear as the signal man believed, since even then enemies must have been creeping toward him, though utterly unseen in the darkness.
The rapid discharge of guns, and the loud outcries of men engaged in desperate warfare, thrilled the boys. They could not see a single figure, but the spiteful flashing of firearms, as they were discharged, told them that the fight was not all one-sided, and that the Germans must be resisting capture with their usual valor.
All at once they heard another sound.
"It"s the motor--the aeroplane man has managed to get going!" exclaimed Rob, instantly comprehending what that meant.
In order to rise, after starting his machine, it was necessary for the aviator to first skim along the field for a little distance, and gradually gain an impetus which, at the proper instant, results in a slow ascent.
Of course he was taking all sorts of desperate chances in making this blind venture; but his life was at stake, if caught. Besides, he undoubtedly must have examined the nature of that level stretch of ground before, and selected it as a landing place on account of its good qualities.
"He"s heading this way, Rob!" exclaimed Tubby, almost in a panic.
"If he b.u.t.ts into this wall it"ll spell his finish!" added Merritt.
"No danger of that," said Rob. "He knows every foot of ground around here. But duck down, everybody. They will fire a volley after him, and we might get in line of the bullets."
Tubby dropped flat, forgetting that the high stone wall was as good a breastwork as any one could want.
Just as Rob had antic.i.p.ated, there was a series of explosions, and they could even hear the patter of bullets striking the piled-up stones composing the wall.
This was enough to tell them that the fleeing aviator had headed straight toward the spot where they were crouching. And, as the rattle of his machine grew louder, they realized that he was approaching them with considerable speed.
Then, with an additional clatter, the Taube pa.s.sed over the wall, clearing its top by not more than ten feet.
"Keep down!" exclaimed Rob, feeling Merritt beginning to make a move, and afraid lest he should stand upright in order to better follow the progress of the aeroplane.
It was well he spoke when he did, for another burst of firing came. The soldiers were sending random volleys after the fleeing airman, in hopes of injuring his machinery or wounding the aviator himself.
"That was sure a great getaway!" bubbled Tubby, still seated there on the ground.
"But I rather think they winged him," added Merritt, possibly with a note of regret in his voice.
It was not that he felt any particular sympathy for the German cause; but, boy-like, he could admire grit and daring, no matter under what flag it might be found. That bold flight of the Taube operator in the face of the flying missiles was quite enough to arouse the spirit of any one with red blood in his veins.
"What makes you say that?" asked Tubby, not meaning to remain in ignorance when he possessed a ready tongue.
"I was pretty sure the machine wabbled as it pa.s.sed over," said Merritt.
"My opinion, too," Rob chimed in. "It seemed to me he was trying his best to get it to mount, but it balked. That could only mean something had gone wrong with the machinery, or else a wing had been fractured."
"Huh! you talk just like the machine might be a baseball pitcher,"
commented Tubby. "But, if that"s the case, the chances are he"ll drop to the ground right away, or else smash up against some tree."
"Just what may happen to him," agreed Merritt.
"You"ll notice that the sound of motor and propeller has suddenly died out," suggested Rob, "which I take it looks pretty rough for the man-bird."
"Oh! that would be too bad, now!" Tubby whimpered, as he imagined he could see the bold pilot of the crippled flier dashed to the ground amidst the wreckage of his machine.
"Well, the shooting seems to be over!" remarked Merritt.
"I wonder what happened to the spy?" Rob observed, as he stared over the top of the stone wall toward the spot where the late confusion had taken place.
They could still see that little glow, proving that the lantern had not been kicked over in all the riot when the creeping Belgians had pounced on the enemy.
"Would it be wise for us to head over there now, Rob?"
Plainly Merritt was curious to know what had happened, and his manner of putting this question to the patrol leader showed that he would never be satisfied unless they made some sort of attempt to solve the mystery.
This time he found Rob more agreeable. Conditions had changed considerably since the leader had put his foot down upon any suggestion that they thrust themselves into the game. The Belgians were their friends, and they could not believe any danger was to be feared from that source.
"We might walk over that way," Rob admitted slowly; "that is, if Tubby can get over this wall."
"If not, he could wait for us here," suggested Merritt, with a chuckle.
"I see myself waiting all alone on the other side of the wall, while you two step forward and find out all there is going on. I can climb walls, all right, if somebody only gives me a little boost. Try me, and see, Rob. That"s a good fellow!"
Of course Rob was ready to lend the desired a.s.sistance; and as Tubby secured a hold on a large stone that crowned the wall, he was able to hunch himself up, puffing and grunting at a great rate.
It was easy enough to get down, if one did not care how he fell; but Tubby proved fortunate in finding toe places where he could secure a hold, and in some fashion managed to "dismount."
He pattered after his two chums, who were already moving toward the middle of the big field.
