<h2>CHAPTER XI</h2>
<h3>Tapping the Enemy's Wire</h3>
<p>The following morning all of those who had arrived on the transports
were established in a concentration camp, but it was merely for the
purpose of inspection of men and equipment, and was not to be for long.
It was that same day that the three boys from Brighton were for the
first time assigned to a regular unit of the Signal Corps.</p>
<p>Also, with a real thrill, they learned that they were almost immediately
to see war service, for American troops were already in the trenches.</p>
<p>It was a happy circumstance for the three lads that they had had such
close association with Lieutenant Mackinson, for, without question, he
already had gained an enviable reputation, and when he was ordered to
emergency service, and told he might choose the five men who were to be
under his direction, his three assistants on the trip across were the
first ones named.</p>
<p>The other two were Tom Rawle, a fellow<SPAN class="pagenum" name="page_119" id="page_119" title="119"></SPAN> proportioned like their first
friend in the service, Sergeant Martin, and a wiry, energetic,
quick-speaking youth named Frank Hoskins.</p>
<p>"We have a long trip before us," Lieutenant Mackinson informed them,
"and we leave here on a special train in two hours. In a short time we
will be in the thick of it."</p>
<p>It was joyous information for the five, and they set about their few
preparations with a zest only experienced by boys knowing they have
important work to do, and feeling capable of doing it well.</p>
<p>"How long have you been over?" Joe asked of Tom Rawle.</p>
<p>"Got here two weeks ago," the big fellow answered. "But I haven't had
any real service yet. I was assigned once to Cambrai, but before I
reached there a big drive was under way, the Germans were being pushed
back, and the detachment to which I had been assigned was so far forward
that my orders were changed and I was sent back here."</p>
<p>"Did you get within sound of the big guns?" asked Slim excitedly.</p>
<p>"I should say so," answered Tom Rawle. "And so will you within a few
hours. Isn't that so, Hoskins?"<SPAN class="pagenum" name="page_120" id="page_120" title="120"></SPAN></p>
<p>"Yes," answered Frank, "and when you do you'll get a new idea of the
fighting qualities of the French and Americans, going shoulder to
shoulder against the Boches."</p>
<p>"Hoskins knows," explained Rawle, "for he got nearer than I did."</p>
<p>"Only for a short time," Frank corrected modestly, "but they called it
my 'baptism of fire.' I was out one night with an advance party. We were
nearly ambushed, and had to beat a quick retreat."</p>
<p>"Well, tell them all about it," demanded Tom Rawle, impatient at Frank's
unwillingness to talk much about himself.</p>
<p>"Oh, they fired on us from a distance of about a hundred yards," the
other lad admitted, "and it was a surprise party for fair, I can tell
you. When bullets begin singing around your head for the first time, and
especially when they come without any warning from the enemy, or any
expectation on your part, it does give you rather a peculiar sort of
feeling.</p>
<p>"They got one of the fellows in our party with a bullet in the arm, then
we all dropped on our stomachs and wriggled our way back into our own
lines without any further damage. But we did some rapid wriggling, you
can bet.<SPAN class="pagenum" name="page_121" id="page_121" title="121"></SPAN> There wasn't any time wasted by any of us, and inasmuch as we
were apparently outnumbered, we did not fire back, for fear of giving
them an exact range of our whereabouts.</p>
<p>"After that I was sent back along the rear lines on an inspection trip
which brought me all the way to this point, where I was held for the
formation of this unit."</p>
<p>"Say, that must be thrilling—to be a member of an advance party like
that," said Jerry, his enthusiasm as fiery as his hair. "I wonder if
we'll get any work like that?"</p>
<p>"You sure will," responded Rawle, "and plenty of it. You needn't worry
on that score."</p>
<p>At that moment Lieutenant Mackinson arrived to inquire if all their
preparations had been made, and if they were ready to board the special.</p>
<p>"All ready," they answered, and the lieutenant led the way to the train.</p>
<p>They found several others already aboard, who were to make at least a
part of the trip with them. There were half a dozen men who had been
slightly wounded in the trenches, and now, completely well, were
returning to their regiments. Also, there was a wire company of the
Signal Corps,<SPAN class="pagenum" name="page_122" id="page_122" title="122"></SPAN> which was going to join another American unit.</p>
<p>For the first three or four hours of the trip the lads, even including
Hoskins and Rawle, found the returning young veterans the center of all
interest, and from them they heard many serious and amusing stories,
many true tales of the attack and retreat, of shot and shell and
shrapnel and the hand grenade and the poisonous gas bombs thrown by the
Boches.</p>
<p>And then, one by one, the soldiers of Uncle Sam dropped off into long
and restful slumber—slumber that was to fit them for hard and difficult
duties ahead.</p>
<p>"This is where we get off," finally announced Lieutenant Mackinson,
shaking the lads into wakefulness. "We leave the train here and travel
the balance of the distance by automobile."</p>
<p>Never had the boys seen such a powerful looking car as that to which an
orderly led them. Without the waste of a moment they climbed
in—Lieutenant Mackinson, our three friends, young Hoskins and the
towering Rawle. In another instant they were speeding across the country
with the break of dawn.</p>
<p>But their trip now was far different from<SPAN class="pagenum" name="page_123" id="page_123" title="123"></SPAN> the one they had had across
England. Where, in that country, they had seen big concentration camps,
and men preparing for war, with an occasional evidence of war's effects
in a building wrecked by a night air raid, here, in the eastern part of
France, they came upon actual war in all its fateful progress, with
whole towns demolished, forests and orchards blotted out—stark ruin
written over the face of the earth.</p>
<p>With a clear right-of-way, their high-power machine swept past
ammunition and food trains—long strings of powerful motor trucks
driving toward the scene of action. They came upon towns and villages in
that area known as "behind the lines," where French, American, Belgian
and British soldiers were recuperating after hard days and nights in the
front-line trenches.</p>
<p>By this time they were well within sound of the heavy guns, and their
driver told them that the artillery duel then going on had been in
progress for forty-eight hours at least.</p>
<p>"Sometimes it lasts for a week or more, you know," he said, "in
preparation for a great infantry advance. But I understand that this
time they expect to go forward before the end of to-day."<SPAN class="pagenum" name="page_124" id="page_124" title="124"></SPAN></p>
<p>"Which, means," added Lieutenant Mackinson, "that we probably will get a
chance to get right into the thick of it."</p>
<p>On and on they went, and nearer and nearer to the scene of actual battle
they came. They passed the third-line trenches, and now, in places, they
seemed to be in a straight line with some of the concealed artillery
that was pounding away at the enemy in terrible detonations that shook
and rocked the ground every minute.</p>
<p>At the second-line trenches their orders called for a halt. They did not
have to be told that there was "something doing." The road, so far as
the eye could reach backward over the route they had traveled, was a
constantly moving line of motor trucks, coming forward with men and
shells, while out ahead of them, tremendous and menacing, big tanks—the
biggest things the boys ever had seen propelled on wheels or
tractors—were pursuing their uneven course toward the front, in
preparation for a new kind of assault.</p>
<p>"They look like miniature battleships on land, don't they?" exclaimed
Slim.</p>
<p>The others agreed that it was about the best description that could be
given of these<SPAN class="pagenum" name="page_125" id="page_125" title="125"></SPAN> massive fighting machines, equipped with guns and men,
that could travel with their own power practically anywhere, across
shell holes, over trenches, through barbed wire—the most human piece of
war mechanism that had yet made its appearance on the battlefield.</p>
<p>Summons to a long-delayed meal gave a welcome interruption to their
guesses as to just what their first duties would be, and they had
scarcely finished their substantial rations of food when an orderly
informed Lieutenant Mackinson that he was to report at once to the field
headquarters.</p>
<p>"Await me here," he said to the five men under his immediate command. "I
probably will be only a short time."</p>
<p>And, indeed, it seemed to them that he had hardly time to reach the
headquarters when he was seen returning hurriedly. He gave some hasty
instructions to the chauffeur, and the latter immediately began a quick
examination of his engine and tires, which promised another early move.</p>
<p>"We go forward as far as we can by automobile again," the lieutenant
informed them, "and after dark to-night we are to establish an outlying
communication from the farthest skirmish points to headquarters."<SPAN class="pagenum" name="page_126" id="page_126" title="126"></SPAN></p>
<p>Almost as he finished the sentence, they were started, but now their
progress frequently was impeded, and occasionally a shell broke so close
to them as to jar the machine from its course.</p>
<p>None of the men in the rear seats of that car were cowards, but, aside
from Hoskins, it was their first experience under actual fire, and they
marveled at the coolness of the driver, who seemed not to mind at all
the dangerous quarters they were in.</p>
<p>When they climbed out of the machine, half an hour later, Joe remarked
upon it in tones of open admiration.</p>
<p>"It's nothing," the youthful chauffeur replied. "You'll get used to it,
too."</p>
<p>As he turned the automobile and started backward, Slim suddenly
remembered that they hadn't even heard his name.</p>
<p>"Don't know it," said Hoskins, "but he was wounded twice in the
trenches, I heard while we were waiting for the lieutenant. That's why
he's driving a car now. He has seen enough service to know that
nervousness doesn't help."</p>
<p>They had been directed to the quarters of Major Jones, in charge of the
Signal Corps men in that section, and it was with considerable<SPAN class="pagenum" name="page_127" id="page_127" title="127"></SPAN> surprise
that the boys learned, upon arriving there, that they were to accompany
the lieutenant into the superior officer's presence for instructions.</p>
<p>He was a man, they found, about forty years old, already grizzled and
hardened by his field experience. And he knew how to convey orders and
transact business without a moment's delay.</p>
<p>"You are to follow the red-ink lines on this map," he told Lieutenant
Mackinson, as they all leaned over his desk to follow the tracing of his
pencil, with which he showed them the course they were to take.</p>
<p>"When you have reached this point"—indicating a heavy spot about midway
of the map—"you will seek a suitable location from which to establish
communications. You will determine whether it can be done by wireless.
As soon as you can do so, report what progress you have made. Use every
caution, for you will be in the country occupied by the enemy. You
should leave here about seven o'clock this evening. It is now six."</p>
<p>Fifteen minutes later they had examined their arms and equipped
themselves with a full supply of small-arms ammunition,<SPAN class="pagenum" name="page_128" id="page_128" title="128"></SPAN> portable
wireless instrument and antennæ, and three rations each of eating
chocolate.</p>
<p>The latter article is dispensed to every soldier in the American armies
just prior to an engagement in which he may become separated from his
unit or companions, and, if wounded, might otherwise starve to death.</p>
<p>The remaining three-quarters of an hour they spent in close study of the
map that Major Jones had given them, and promptly at seven o'clock they
started upon the dangerous mission.</p>
<p>With nightfall the big cannonading had noticeably shut down, but to the
south of them artillery firing still could be heard distinctly. It was a
black night and they proceeded with the greatest caution.</p>
<p>They did not dare use the flashlights that each of them carried, and
frequently all of them would have to drop suddenly flat upon the ground
as a big rocket went up from either side, lighting the whole section for
trace of skirmishing parties.</p>
<p>In this way they went forward, yard by yard, until they reached a thick
clump of trees. There, after listening intently for several minutes
without hearing a dangerous sound, they spread out their coats,
tent-like,<SPAN class="pagenum" name="page_129" id="page_129" title="129"></SPAN> while Lieutenant Mackinson, with gingerly flashes of his
light, examined the map again, to make certain of their location.</p>
<p>They had hardly progressed a hundred feet further when the unlucky Slim
tripped and went sprawling on the ground with a pained but suppressed
grunt.</p>
<p>"Sh-h-h-h!" warned Lieutenant Mackinson in a whisper, while Tom Rawle,
quietly chuckling at the fat lad's misfortune, aided him to his feet.</p>
<p>"Down flat!" said Mackinson again, as he discerned several shadows
moving across a space a considerable distance to the north of them.</p>
<p>For fully ten minutes, which seemed like an hour, they lay there, not
daring to move. They watched the enemy scouting party get a like scare,
and then, after what seemed to be a whispered consultation, turn back to
the German lines.</p>
<p>"What did you fall over?" the lieutenant finally asked of Slim, in a
scarcely audible tone.</p>
<p>"I just found it," replied Slim. "It's a wire. Here, let me have your
hand." And he guided the lieutenant's fingers to that which had been the
cause of his downfall.<SPAN class="pagenum" name="page_130" id="page_130" title="130"></SPAN></p>
<p>"Copper!" exclaimed the lieutenant. "Hoskins, let me have that kit."</p>
<p>And without the aid of a light he extracted from the leather case which
Hoskins gave him a very small telegraph instrument. The instant it was
attached to the wire the receiver began to tick irregularly.</p>
<p>Neither Rawle nor Hoskins understood German, but to the others they were
words easy to translate.</p>
<p>They had accidentally struck an enemy wire and had tapped it! That part
of the message which they had intercepted read:</p>
<div class="blockquot"><p>"—lead enemy to believe whole attack centered from your
position, but main assault will be a flank move around Hill 20"</p>
</div>
<p>At that instant a fusillade of bullets cut the ground all about them,
and the six men suddenly realized that they were under a pitiless and
well-directed machine-gun fire.</p>
