"Oh! not different, only more of it," Tom explained. "On our scouting expedition last night we found that the Huns have a series of extra strong nests fixed for us to-day. We"re to arrange with the batteries for signaling in regard to these, for they would take too big a toll of the boys if rushed like the common variety, where there"s only one gun and a couple of Boches to handle it."
"Glad to hear it," snapped Jack. "So far neither of us has had the good luck to locate a big hornets" nest. I hope our chance comes to-day. I"ve always wanted to see how that game worked."
"Well, perhaps you"ll know more about it when we meet to-night, which it is to be hoped will come about," said Tom, a bit seriously.
Indeed, in those strenuous times none in the army could be at all certain he would be in the land of the living a few hours ahead. In particular the daring air pilots who so often took great hazards were in peril. Yet the men went about their duties with apparently light hearts.
"Here"s Harry!" exclaimed Jack, a moment afterwards, as a wideawake looking young fellow stopped for a minute near them, being on the way to his hangar in company with his a.s.sistant.
Harry Leroy had become very friendly with the two air service boys, although they had not known him until long after reaching France. But he was a genial boy, known to be an unusually clever air pilot and well on the way to being cited as an American ace, for he had now disabled his quota of enemy machines.
"They tell me we"re going to make a big dent in the Boche lines to-day, fellows!" he sang out, with one of his genial smiles. "Our commander has a programme laid out that"s said to be pretty ambitious. Some of us are even hoping it may turn out to be the real start for the Rhine, and that we"ll clean up this old Argonne region pretty soon now."
"Slow but sure is our policy these days, Harry," Tom remarked. "It takes a heap of time, and makes a hole in our reserves; but the work is done so thoroughly that it"ll stay done. And soon we"ll be out of the woods."
"The boys are longing for that day to come," said Harry, about to start on once more. "They"re just sick and tired of this kind of fighting.
Wait till we get Fritz out in the open, and you"ll see how well rush him back like hot cakes! So long, both of you. Here"s wishing you the best of luck and another notch in your stick by nightfall."
Of course Tom had secured another observer in place of the poor fellow who had been so badly injured on that other flight of his. His arm, too, had healed.
Shortly afterwards the air service boys received word to start, and along with four other planes mounted upward like birds on the wing.
So far as appearances went the scene below them did not differ materially from the preceding day. There was the same vast stretch of grim forest known as the Argonne, with occasional openings here and there, "breathing spots," they might be called. These marked sites of farms, timber or cutting authorized at some past day by the French government, that controlled the wonderful tract of woods, possibly the largest in all France. Smoke was already rolling upward in great volumes while the air pulsated with the fearful crash of every imaginable type of gun, both large and small. As the day wore on all this was bound to increase greatly, the impetuous Americans pushing forward and wresting rod after rod of the forest from the enemy, paying the price without a murmur, but grimly determined.
Jack having attained the required alt.i.tude commenced "fishing." That was his way of describing the means employed for learning where the Huns were lying in wait, ready to pour in a deadly machine-gun fire on the first detachment of Yankees that came along.
The darting plane would dive down close to the tops of the tall trees, and thus offer such a tantalizing bait that the concealed Hun gunners, unable to resist the temptation, were likely to shoot at the cruising machine.
Of course this would expose their secret hiding-place, but inaccurately located in the darkness the night before, and it was the business of the observer to signal his discovery back to those who were on the watch.
The consequence would be that instead of making a frontal attack on that particular nest, the infantry would resort to Indian tactics, making a flank movement that would carry them past, then closing in from the rear. At a given signal some of their mates would make a hostile demonstration in front to chain the attention of the gunners, while others would creep up so close from the rear that they would be able to get both men.
Of course this meant that the venturesome fliers would be taking additional risks. When that machine-gun should start to pepper their plane they were likely to be struck by one or more of the shower of missiles coming hissing up like enraged hornets. What matter, when they were accepting chances just as desperate every minute of the time they remained aloft?
Jack and his a.s.sistant, Morgan, found themselves busily engaged inside of ten minutes. They swooped so low that suddenly there was a burst of fire, and bullets commenced to cut through both wings of their plane.
The body had been sheathed in metal that would serve to ward off most of this hail, but despite this they took many chances of a mishap.
Immediately Morgan noted the exact spot from which the firing came, so he could locate it in sending out his signal of warning. Jack meanwhile was doing his part, dodging in zigzag curves in all directions in order to baffle the aim of the Hun gunners.
Then, too, the trees helped greatly to conceal them from the observation of the enemy below; so that the firing kept up for a very brief time only. But their trick had succeeded. The Boches dared not come out from their place of concealment lest they be discovered and shot down by the stealthily advancing Americans. Perhaps they were even chained there, as frequently happened.
In consequence they had to cower under their shelter and wait until, later on, without warning, there would come loud shouts from the front, and when they craned their necks to catch the first glimpse of the foe shots from the rear would clean up that nest.
Morgan started with his signal work immediately after they had climbed to the proper alt.i.tude, where they might work without being in too great danger from the "Archies," or anti-aircraft guns.
As soon as he had a response, and knew that his directions were accurately noted, he announced the fact to Jack. They were then ready to begin all over and start "fishing" again.
It was very exciting work, and Jack Parmly gloried in it. Though he had to take additional chances in order to tempt the Hun gunners to betray their cunningly arranged coverts, there was also a satisfaction in knowing that by so doing he and his a.s.sistant were saving many precious lives of the infantry regiments down in the forest that had proved a graveyard for thousands.
A second time did they get a "bite." Again was the retreat conducted in the midst of a rattling volley, with hurtling missiles burning the air all around them, as well as beating a lively tattoo on the armored parts of their plane.
After that they flew higher, in the hope that some enterprising Boche flier, seeing their challenge, would come over to give them battle. For half an hour, they kept this up, and then, as they tempted forth no adversary, determined to drop down once more and root out a third nest before going in for the noonday meal.
"They"re at it hammer and tongs to-day for fair!" called out Morgan, as he used his binoculars and picked out spots far below where there seemed to be open fighting going on. He could discover bodies of German troops being rushed forward and then falling back with decimated ranks before a fierce flame of shot and sh.e.l.l poured in by Yankee batteries.
"Getting desperate, that"s what!" announced Jack, starting a dip that by stages would take them down once more into the dangerous quarter of treetops under which lurked the deadly foe with his thousands of rapid-fire guns.
Other planes were in sight here and there, carrying out similar tactics with more or less success, according to the daring of the pilot in tempting the Huns beyond their power to resist. Jack determined to pa.s.s further on and see what he could unearth in a new quarter.
What he and his chum had been talking of that very morning was still fresh in his mind. How he would like to discover one of those unusual nests where half a dozen or more gun crews lurked, ready to hold up that entire sector of the advancing line, so the American troops would be unable to reach their objective for that day at least.
So it was in the hope of attaining this end that he now flew to another section of the forest which he had been desirous all morning of visiting, under the impression that it might yield the bag to which he aspired in his search for game.
As they circled over the tree tops Morgan was turning his gla.s.ses to the best advantage. Jack kept trying to cover the ground systematically, and yet making numerous quick jumps so as to disconcert the enemy should a sudden fierce burst of firing announce that a nest had been located.
All at once Morgan gave a loud cry. It seemed to spell victory, and Jack instantly called out:
"Struck oil, have you, Felix? Where away does it lie?"
"Look down to the left and you"ll just glimpse what seems to be the stone base of an old abandoned windmill, I think, Jack. All overgrown with weeds and brush, it is too. I saw a number of men moving about, and some of them were crouching back of their biggest machine-guns. This is one of those jumbo forts we"ve heard of; no mistake about it either."
"Grab off the location to a dot then, Felix, and we"ll see what can be done for those waiting Yankee batteries!" snapped Jack, greatly excited, as well as pleased, by their important discovery. "Let me know when you have your landmarks, and I"ll elevate, so we can get in touch with the battery observer."
"It"s the king-pin of all their nests, Jack, a regular bouncer, I tell you!" cried the other, using his gla.s.ses again to advantage.
"All right then," the pilot a.s.sured him, "we"ll see that their name is mud before much longer. Ready, Felix?"
Instead of giving Jack the reply which the other expected the observer gave a sudden startled yell.
"They"ve got us trapped, Jack! Sure they have! Look up!" came his warning shout, and as the pilot craned his neck to obey he discovered no less than three big German Gotha battleplanes hovering over them, waiting to engage them in a most unequal combat.
CHAPTER VII
"MOPPING "EM UP!"
FROM below there suddenly burst a dangerous bombardment. The German gunners hidden in the camouflaged pile of rocks had apparently decided that the airmen in the two-seated plane hovering above had discovered their place of concealment, and, unable to endure the thought of being flanked by the oncoming boys in khaki, had opened fire.
Of course their plan was to bring down the American machine and seal the lips of those who flew in it before they could communicate the nature of their discovery to their comrades.
This made the situation doubly perilous for Jack and Morgan. If they attempted to rise, as discretion suggested, there were those three grim monster Hun Gothas waiting to envelop them with an avalanche of gunfire.
This could have only one result; namely, the destruction of the plane bearing the totem of the Red Indian"s head.
It was a time for quick decision. As the deadly missiles from below continued to pepper the air around them, and even beat a tattoo against the body of their plane, Jack started into a series of wigwag evolutions which he had evolved for just such a desperate situation.
