# Air Service Boys Flying for Victory/Chapter 12

CHAPTER XII
A LIVELY CHASE
"They've gone," presently whispered Tom, in a disappointed tone.
"Only hiding somewhere near by," Harry assured him, equally careful to lower his voice. "We'll begin to circle around, and presently rout them out. Be ready to jump the first chance you get, and let out a whoop at the same time. It'll give 'em a shock, and start 'em to running. Then we'll soon have a pack on their heels."
"What if they use their trench grenades on us?" asked Tom.
"Not likely to except as a last resort. But we've got to take the chances. Dodge, that's all. Now to swing around the big hangar."
Harry squeezed his companion's arm while saying this. Both of them were fairly quivering with the excitement, just as highly strung race horses can be seen quivering while prancing up and down awaiting the tap of the bell that summons them to the wire for the start.
​It was not pitch-dark, but even the possessor of keen eyesight would have had to look closely in order to make certain that a moving object was a human being and not a dog.
Harry's surmise proved to be well founded, for they quickly discovered a suspicious movement close to the large hangar. Yes, the two Hun spies were undoubtedly there, and already busily engaged in doing something that could only mean trouble for the American escadrille.
Closer the pair of watchers crept. They could now hear the men whispering as they worked, and Tom even believed he caught a guttural German word used. This convinced him their theory was founded on fact, and that these were secret enemies in the camp.
Another half minute and he felt Harry nudge him. That meant the other believed the time had arrived for them to make their leap; and when he felt his companion start Tom stirred himself.
Both let out a yell as they sprang forward. Tom more than half expected to hear an explosion, thinking the Huns, on finding themselves caught in the act, would fire their grenades promptly.
Nothing of the kind came about. Instead both men instantly dropped flat and started to roll away with incredible swiftness, as though escape was the first thought in their minds.
​Tom hurled himself through space. His intention was to pin one of the spies to the ground and try to hold him there until help came. Their outcries would of course arouse every man within hundreds of yards of the spot, and lights must soon be brought to bear on the scene.
Although Tom's calculations may have been all right, he did not meet with as much success as he had probably anticipated. Perhaps the wary Boche guessed what was coming; at any rate he succeeded in squirming from under, and when Tom landed it was only to feel the other rolling out of his reach.
But he went after him like lightning, bent on attaining his goal.
The Hun was scrambling desperately in the endeavor to get on his feet. Tom hurled him over, and closed with him. Finding his escape thus cut off, the other commenced to fight like a tiger, clawing and struggling furiously.
They had it "hammer-and-tongs" for a brief space of time. Then Tom slipped and lost his grip, upon which the other rolled over several times, got to his knees, then his feet, and started to run.
But he counted without reckoning on the staying qualities of the American. Tom had always been called a "sticking-plaster" by his fellow players on the football field. He was not to be ​counted out of the game until the last whistle sounded and the referee's falling hand closed the fun.
So he was after his man with grim determination not to let him get away. Having gone to so much trouble, and received in addition several scratches in the contest, he meant to keep everlastingly at it.
The Boche dodged to one side, as there were men running toward them, and already several lights had sprung up. Tom was close at his heels, and gaining rapidly, being spurred on by an ambition to complete the good work he and Harry had started.
He saw the spy glance back over his shoulder. The situation must have appeared very grave to the other, who could expect to meet with short shrift if caught in the act of trying to destroy the hangars and planes of the American aviators in this bold fashion.
Just then Tom saw the man raise his arm. Guessing what he intended to do, the Yankee air pilot dodged just in time. Some object went hissing past, close to his head. An instant later there was a loud explosion in his rear that seemed to make the very air quiver.
Of course the Boche had hurled a grenade with the intention of making further pursuit on the part of his persistent adversary impossible.
​Tom hoped that was the extent of his supply of such ammunition, for he might not be quite so successful in avoiding the bomb another time.
Again was the fleeing spy compelled to whirl aside because of threatening peril ahead. Dodging in and out between the khaki-colored canvas field hangars he sought desperately to throw Tom off his track; but no hound ever followed its quarry with more pertinacity than the Yankee air pilot followed now.
Then something happened. Tom came in collision with a runner, so that the two of them fell headlong to the ground. By instinct Tom hugged the other in his arms. He suspected on the spur of the moment that this might be the other spy, trying to elude Harry, and cutting across his track by the merest chance.
The fellow struggled furiously, but Tom managed to get a good hold on him, and kept it tenaciously. As the other was also clutching him his further pursuit of the fleeing spy seemed doomed to failure; and so Tom felt that the only thing left was to make sure of this party.
"Hey, Tom, let go! You're choking me!" came a voice that electrified him, and caused him to release his clutch.
After all it was Harry upon whom he had fallen, Harry who having lost all track of his ​man was rushing wildly this way and that in hope of once again getting in touch with the fellow.
"Quick, before it's too late, join me!" shrilled Tom, scrambling to his feet again as best he could, and feeling angry because of this ridiculous accident. "There he goes, Harry! After him again!"
So they both started once more to run at top speed. The agile spy had been able to put considerable distance between them while his pursuers struggled on the ground, and seemed likely to escape. But there was one thing that stood in his way.
Men were running this way and that in every direction, calling to one another, and trying to understand what all the row was about. A squad of oncoming hostlers blocked his passage. They evidently were beginning to get light on the situation, for discovering the panting runner they now set up a concerted shout.
This compelled the hunted Boche to turn again on his heel, and so he lost a portion of his previous gain. Tom took fresh heart on seeing this. Given one or two such lifts as this, and he believed he would again come to hand grips with the fellow. And with Harry close at his heels he fancied the next encounter would surely terminate badly for the Hun spy.
​"Spread out some, Harry!" he managed to shout.
His object in saying this was to make it more difficult for the Boche to hold his own when necessity compelled him to veer to one side. They dodged the hangars that barred the way, running in and out of the lines with the swiftness of a hare followed by the eager hounds.
Once a waiting figure tried to bar the path of the spy, only to be promptly bowled over. Desperation nerved the arm that struck that blow. The German knew that his chances were almost at the zero mark, and for the time being he was like a wolf at bay, ready to snap right and left and do what damage he could before yielding himself a prisoner.
Once more Tom had made a gain. The Fates were favoring him, it seemed, and with set teeth he kept up the hot chase.
Suddenly the Hun collapsed.
Tom almost fell over him as he ran on; and when Harry came up was bending above the spy, muttering to himself after the manner of a sadly disappointed person.
"What rotten luck for us, after all our work, Harry!" he complained, to the utter bewilderment of his comrade.
"I don't get your meaning, Tom!" exclaimed ​Harry. "This is one of the Huns, all right, and we've got him at last. What is there to kick about, I'd like to know?"
"Why, don't you understand? He's wounded!" said Tom scornfully.
"Wounded! How?" echoed the other, still groping for the truth.
"Somebody shot him in the leg!" explained Tom, in disgust. "Just as I was bound to jump him in another ten seconds! Did you ever hear of such tough luck? Took the wind right out of our sails, he did, by using his gun. If he'd put a bullet in my leg I could hardly feel madder, for a fact."
Harry, however, quickly chuckled, as though he did not look at the matter in the same way as his chum seemed to.
"Oh, well, the main thing isn't that we'd get a little glory from the capture of the Hun," he said, "but that their desperate game has been blocked. But this chap seems to be groaning as if suffering, Tom. He ought to be taken care of, Boche or not."
"Yes, that's right, Harry," added the other, for the time being crushing down his disappointment.
As some of the attendants of the aviation field came up just at that moment there was need for ​explanations. Among them Tom noticed one who, as he well knew, had charge of the hangars during the night.
"Lieutenant Simmons, here's a Boche spy who, with a companion, was trying to bomb the big Beresford plane. Sorry we couldn't round up both of them. This fellow has been shot, and ought to have attention. Now, Harry, if you don't mind, we'll step around to your hangar and look into the little job that brought us over here from the camp."
Tom really wished to get away from the crowd that was gathering. He had no liking for being made an object of special interest. Although always eager to attempt unusual exploits, it was only to please himself, and not because of any reward or a morbid desire to be looked on as a hero.
Harry was not quite as diffident, and might have liked to linger a bit to explain further how they had managed to discover the creeping figures, and, having their suspicions aroused, closed in on them.
"I can see you later, Lieutenant, and answer any questions you may want to ask about this stuff," he remarked, as he followed Tom away from the group.
Tom was still "huffy" as Harry called it. He seemed to feel that the ambitious marksman who ​had taken a pot-shot at the runner ahead had really cheated him out of half the pleasure accompanying the capture of the spy.
"I heard one big splash," Harry said, "which I take it was made by a trench grenade. Did that Boche try to knock you out, Tom?"
"Oh, he let loose with one of his sort, but it was the easiest thing going to duck under. He's got a lot to learn about flinging those little knockers underhand. It takes a baseball pitcher to do the trick right. How about your man, Harry?"
The other gave a grunt of disgust.
"Nothing doing with that slick dodger, I tell you, Tom. He must have been a premium sprinter when at home, for the way he dodged in and out made my brain reel. I kept after him as best I could, but, shucks! he was in another class from me. And so I lost him in the shuffle. He disappeared just like a wisp of smoke in the breeze."
"But you were still running like a hare when we banged into each other, unless I'm greatly mistaken," continued Tom humorously.
"Sure I was! Trying to get a fresh glimpse of my duck. When I hit you I thought it was that Boche, and then a light fell on your face, coming from that head-lamp on a motor truck some one suddenly turned on. I reckon I'll have ​a beautiful lump on my forehead where I struck against a pole while running. It knocked me flat, and that was when I lost my man."
Tom now began to laugh.
"A pretty lively skirmish, all told, when you come to think of it," he observed. "I'll have to forget about that chap who was too quick on the trigger, and only add up results. One Boche spy captured, wounded; and the other gets away. But he's had his scare good and hard, and there's little danger of his giving us any more trouble."
Whatever became of the captured Boche neither of them ever knew. Perhaps he was simply taken to the hospital and treated for his wound, as so many of his fellow Huns had been; and then again did time permit and opportunity arise he might be tried by drumhead courtmartial on the serious charge of being a spy.
Having satisfied themselves with regard to the matter in dispute, the two boys later on returned once more to the camp and sought to secure some much needed sleep, fully conscious that the duties of the coming day would again sap their energies and bring them renewed chances for thrilling action.
