<h2><SPAN name="CHAPTER_I" id="CHAPTER_I">CHAPTER I</SPAN><br/> <span class="subhead"><span class="smcap">The War in and Under the Ground</span></span></h2>
<p class="drop-cap3"><span class="smcap1">For</span> years the Germans had been preparing
for war. The whole world knew this,
but it had no idea how elaborate were their
preparations, and how these were carried out
to the very minutest detail. When the call to
arms was sounded, it was a matter of only a
few hours before a vast army had been assembled—fully
armed, completely equipped, ready
to swarm over the frontiers into Belgium and
thence into France. It took much longer for
the French to raise their armies of defense,
and still longer for the British to furnish
France with any adequate help. Despite the
heroic resistance of Belgium, the Entente Allies
were unprepared to stem the tide of German<span class="pagenum"><SPAN name="Page_4" id="Page_4">4</SPAN></span>
soldiers who poured into the northern part of
France.</p>
<p>So easy did the march to Paris seem, that the
Germans grew careless in their advance and
then suddenly they met with a reverse that sent
them back in full retreat. However, the military
authorities of Germany had studied not
only how to attack but also how to retreat and
how to stand on the defensive. In this, as in
every other phase of the conflict, they were far
in advance of the rest of the world, and after
their defeat in the First Battle of the Marne,
they retired to a strong position and hastily
prepared to stand on the defensive. When
the Allies tried to drive them farther back, they
found that the German army had simply sunk
into the ground. The war of manœuver had
given way to trench warfare, which lasted
through long, tedious months nearly to the end
of the great conflict.</p>
<p>The Germans found it necessary to make the
stand because the Russians were putting up
such a strong fight on Germany's eastern frontier.
Men had to be withdrawn from the western
front to stem the Russian tide, which meant
that the western armies of the kaiser had to<span class="pagenum"><SPAN name="Page_5" id="Page_5">5</SPAN></span>
cease their offensive activities for the time being.
The delay was fatal to the Germans, for
they had opposed to them not only brave men
but intelligent men who were quick to learn.
And when the Germans were ready to resume
operations in the West, they found that the
Allies also had sunk into the ground and had
learned all their tricks of trench warfare, adding
a number of new ones of their own.</p>
<p>The whole character of the war was changed.
The opposing forces were dead-locked and
neither could break through the other's lines.
The idea of digging into the ground did not
originate with this war, but never before had
it been carried out on so extensive a scale.
The inventive faculties of both sides were vainly
exercised to find some way of breaking the
dead-lock. Hundreds of new inventions were
developed. The history of war from the days
of the ancient Romans up to the present time
was searched for some means of breaking down
the opposing lines. However, the dead-lock
was not broken until a special machine had been
invented, a traveling fort. But the story of
that machine is told in another chapter.</p>
<p>At the outset the Allies dug very shallow<span class="pagenum"><SPAN name="Page_6" id="Page_6">6</SPAN></span>
ditches, such as had been used in previous
wars. When it was found that these burrows
would have to be occupied for weeks and months,
the French and British imitated the Germans
and dug their trenches so deep that men could
walk through them freely, without danger of exposing
their heads above ground; and as the
ditches grew deeper, they had to be provided
with a firing-step on which the riflemen could
stand to fire over the top of the trenches. The
trenches were zig-zagged so that they could not
be flanked, otherwise they would have made dangerous
traps for the defenders; for had the
enemy gained one end of the trench, he could
have fired down the full length of it, killing or
wounding every man it contained. But zig-zagging
made it necessary to capture each turn
separately. There were lines upon lines of
these trenches. Ordinarily there were but
three lines, several hundred feet apart, with
communicating trenches connecting them, and
then several <span class="locked">kilometers<SPAN name="FNanchor_1" id="FNanchor_1" href="#Footnote_1" class="fnanchor">1</SPAN></span> farther back were reserve
trenches, also connected by communicating
trenches with the front lines.</p>
<div class="footnote">
<p><SPAN name="Footnote_1" id="Footnote_1" href="#FNanchor_1" class="fnanchor">1</SPAN> A kilometer is, roughly, six tenths of a mile; or six miles
would equal ten kilometers.</p>
<p><span class="pagenum"><SPAN name="Page_7" id="Page_7">7</SPAN></span></p>
</div>
<p>Men did not dare to show themselves out in
the open near the battle-front for a mile or more
behind the front-line trenches, for the enemy's
sharp-shooters were always on the watch for a
target. The men had to stay in the trenches
day and night for two or more weeks at a time,
and sleeping-accommodations of a very rough
sort were provided for them in dugouts which
opened into the trenches. The dugouts of the
Allies were comparatively crude affairs, but the
Germans spent a great deal of time upon their
burrows.</p>
<h3>UNDERGROUND VILLAGES</h3>
<p>When the French first swept the Germans
back out of their trenches along the Aisne, they
were astonished to find how elaborate were these
underground dwellings. They found that the
ground was literally honeycombed with rooms
and passageways. Often the dugouts were
two stories in depth and extended as much as
sixty feet below the level of the ground. In
fact, all along this part of the front, the Germans
had a continuous underground village in
which thousands of men were maintained. The
officers' quarters were particularly well fitted<span class="pagenum"><SPAN name="Page_8" id="Page_8">8</SPAN></span>
up, and every attention was given to the comfort
of their occupants. There were steel
door-mats at the entrances of the quarters.
The walls were boarded and even papered.
The bedrooms were fitted with spring beds,
chiffoniers, and wash-stands, and all the rooms
were lighted with electric lamps. There were
spacious quarters for the men, with regular
underground mess halls and elaborate kitchens.
There were power-plants to furnish steam for
the operation of pumps and for the lighting-plants
and for other purposes.</p>

</div>
<p>There was a chalk formation here in which
were many large natural caves. One enormous
cave was said to have held thirty thousand
soldiers, and in this section the Germans kept
large reserve forces. By digging far into the
ground, the German troops secured protection
from shell-fire; in fact, the horrible noise of
battle was heard only as a murmur, down in
these depths. With characteristic thoroughness,
the Germans built their trench system for
a long stay; while the Allies, on the other hand,
looked upon <i>their</i> trenches as merely temporary
quarters, which would hold the enemy at bay
until they could build up armies large enough<span class="pagenum"><SPAN name="Page_9" id="Page_9">9</SPAN></span>
to drive the invaders out of the country. The
construction of the trenches along some parts
of the battle-line was particularly difficult, because
of the problem of drainage. This was
especially true in Flanders, where the trenches
in many cases were below water-level, and
elaborate pumping-systems had to be installed
to keep them dry. Some of them were concrete-lined
to make them waterproof. In the early
stages of the war, before the trenches were
drained, the men had to stand in water for a
good part of the time, and the only way they
could get about at all in the miry trenches was
by having "duck-boards" in them. Duck-boards
are sections of wooden sidewalk such as
we find in small villages in this country, consisting
of a couple of rails on which crosspieces
of wood are nailed. These duck-boards fairly
floated in the mud.</p>

</div>
<p>Some of the trenches were provided with
barbed wire barriers or gates calculated to halt
a raiding-party if it succeeded in getting into
the trench. These gates were swung up out
of the way, but when lowered they were kept
closed with a rather complicated system of bolts
which the enemy would be unable to unfasten<span class="pagenum"><SPAN name="Page_10" id="Page_10">10</SPAN></span>
without some delay; and while he was struggling
to get through the gate, he would be a
target for the bullets of the defenders.</p>
<h3>HIDING RAILROADS IN DITCHES</h3>
<p>Because of the elaborate system of trenches,
and the distance from the front line to that part
of the country where it was safe to operate in
the open, it was necessary to build railways
which would travel through tunnels and communicating
trenches to the front lines. These
were narrow-gage railroads and a special standard
form of track section was designed, which
was entirely of metal, something like the track
sections of toy railroads. The tracks were
very quickly laid and taken up at need. The
locomotives had to be silent and smokeless and
so a special form of gasolene locomotive was
invented to haul the little cars along these miniature
railroads to the front lines. Usually the
trench railroads did not come to the very front
of the battle-line, but their principal use was
to carry shell to the guns which were located
in concealed positions. Railroad or tramway
trenches could not be sharply zig-zagged but had
to have easy curves, which were apt to be recognized<span class="pagenum"><SPAN name="Page_11" id="Page_11">11</SPAN></span>
by enemy airplanes, and so they were
often concealed under a covering of wire strewn
with leaves.</p>
<h3>PERISCOPES AND "SNIPERSCOPES"</h3>
<p>But while the armies were buried underground,
it was necessary for them to keep their
eyes upon each other so that each might be
ready for any sudden onslaught of the other.
Snipers were always ready to fire at any head
that showed itself above the parapet of the
trench and so the soldiers had to steal an idea
from the submarines and build them periscopes
with which they could look over the top of their
trenches without exposing themselves. A
trench periscope was a very simple affair, consisting
of a tube with two mirrors, one at the
top and one at the bottom, set at such an angle
that a person looking into the side of the tube
at the bottom could see out of the opposite side
of the tube at the top.</p>
<p>Observation posts were established wherever
there was a slight rise in the ground. Sometimes
these posts were placed far in advance of
the trenches and sometimes even behind the
trenches where it was possible to obtain a good<span class="pagenum"><SPAN name="Page_12" id="Page_12">12</SPAN></span>
view of the opposing lines. Sometimes a tunnel
would be dug forward, leading to an outlet
close to the enemy's lines, and here an observer
would take his position at night to spy with his
ears upon the activities of the enemy. Observers
who watched the enemy by day would
often not dare to use periscopes, which might
be seen by the enemy and draw a concentrated
fire of rifles and even shell. So that every
manner of concealment was employed to make
the observation posts invisible and to have
them blend with their surroundings. Observers
even wore veils so that the white of their
skin would not betray them.</p>

<div class="captionh0"><span class="smcap">Fig 1.</span> A "sniperscope" with which a sharp­shooter could take

</div>
<p>Snipers were equally ingenious in concealing
themselves. They frequently used rifles which
were connected with a dummy butt and had
a periscope sighting-attachment. This attachment
was called a "sniperscope." The rifle-barrel
could be pushed through a loophole in
the parapet and the sniper standing safely below
the parapet could hold the dummy butt to
his shoulder and aim his rifle with perfect accuracy
by means of the periscope. It was next
to impossible to locate a sniper hidden in this
way. One method of doing it was to examine<span class="pagenum"><SPAN name="Page_13" id="Page_13">13</SPAN></span>
rubbish, tin cans, or any object that had been
penetrated by a bullet and note the direction
taken by the bullet. This would give a line
leading toward the source of the shot, and
when a number of such lines were traced, they
would cross at a spot where the sniper or
his gun was stationed, and a few shell would
put the man out of business. Dummy heads
of papier mâché were sometimes stuck above
the parapet to draw the fire of enemy snipers
and the bullet-holes which quickly appeared<span class="pagenum"><SPAN name="Page_14" id="Page_14">14</SPAN></span>
in them were studied to discover the location
of the snipers.</p>

<div class="caption0"><span class="smcap">Fig. 2.</span> A fixed rifle stand arranged to be fired after dark</div>
</div>
<p>Sometimes fixed rifles were used. These
were set on stands so that they could be very
accurately trained upon some important enemy
post. Then they could be fired in the dark,
without aiming, to disturb night operations of
the enemy. Often a brace of rifles, as many as
six, would be coupled up to be fired simultaneously,
and by operating a single lever each gun
would throw out the empty cartridge shell and
bring a fresh one into position.</p>
<p><span class="pagenum"><SPAN name="Page_15" id="Page_15">15</SPAN></span></p>
<h3>STEEL BRIER PATCHES</h3>
<p>The most important defense of a trench system
consisted in the barbed wire entanglements
placed before it. Barbed wire, by the way, is
an American invention, but it was originally
intended for the very peaceful purpose for keeping
cattle within bounds. Long ago it was used
in war, but never to the extent to which it was
employed in this world struggle. The entanglements
were usually set up at night and were
merely fences consisting of stout posts driven
into the ground and strung with barbed wire
running in all directions, so as to make an impenetrable
tangle. Where it was possible to
prepare the entanglements without disturbance
and the position was an important one, the mass
of barbed wire often extended for a hundred
yards or more in depth. Just beyond the entanglements
trip-wires were sometimes used.
A trip-wire was a slack wire which was laid on
the ground. Before being laid, the wire was
tightly coiled so that it would not lie flat, but
would catch the feet of raiders and trip them up.
Each side had "gates" in the line through
which this wire could quickly be removed to<span class="pagenum"><SPAN name="Page_16" id="Page_16">16</SPAN></span>
let its own raiding-parties through. Sometimes
raiders used tunnels, with outlets beyond
the barbed wire, but they had to cut their
way through the metal brier patches of their
opponents.</p>
<p>Early in the war, various schemes were devised
for destroying the entanglements. There
were bombs in the form of a rod about twelve
feet long, which could be pushed under the wire
and upon exploding would tear it apart. Another
scheme was to fire a projectile formed
like a grapnel. The projectile was attached
to the end of a cable and was fired from a
small gun in the same way that life-lines are
thrown out to wrecks near shore. Then the
cable would be wound up on a winch and the
grapnel hooks would tear the wire from its fastenings.
Such schemes, however, did not prove
very practicable, and it was eventually found
that a much better way of destroying barbed
wire was to bombard it with high-explosive
shell, which would literally blow the wire apart.
But it required a great deal of shelling to destroy
these entanglements, and it was really
not until the tank was invented that such obstructions
could be flattened out so that they<span class="pagenum"><SPAN name="Page_17" id="Page_17">17</SPAN></span>
formed no bar to the passage of the soldiers.</p>
<p>The Germans not only used fixed entanglements,
but they had large standard sections
of barbed wire arranged in the form of big
cylindrical frames which would be carried
easily by a couple of men and could be placed
in position at a moment's notice to close a gap
in the line or even to build up new lines of wire
obstruction.</p>
<h3>MINES AND COUNTER-MINES</h3>
<p>In the earlier stages of the war it proved so
impossible to capture a trench when it was well
defended by machine-guns that efforts were
made to blow up the enemy by means of mines.
Tunnels were dug reaching out under the
enemy's lines and large quantities of explosives
were stored in them. At the moment when
it was intended to make an assault, there would
be a heavy cannonading to disconcert the enemy,
and then the mine would be touched off. In
the demoralizing confusion that resulted, the
storming-party would sweep over the enemy.
Such mines were tried on both sides, and the
only protection against them was to out-guess
the other side and build counter-mines.</p>
<p><span class="pagenum"><SPAN name="Page_18" id="Page_18">18</SPAN></span>
If it were suspected, from the importance of
a certain position and the nature of the ground,
that the enemy would probably try to undermine
it, the defenders would dig tunnels of their
own toward the enemy at a safe distance beyond
their own lines and establish listeners
there to see if they could hear the mining-operations
of their opponents. Very delicate
microphones were used, which the listeners
would place on the ground or against the walls
of their tunnel. Then they would listen for the
faintest sound of digging, just as a doctor
listens through a stethoscope to the beating
of a patient's heart or the rush of air through
his lungs. When these listening-instruments
picked up the noise of digging, the general direction
of the digging could be followed out by
placing the instrument at different positions
and noting where the noise was loudest. Then
a counter-mine would be extended in that direction,
far enough down to pass under the enemy's
tunnel, and at the right moment, a charge of
TNT (trinitrotoluol) would be exploded, which
would destroy the enemy's sappers and put an
end to their ambitious plans.</p>
<p>A very interesting case of mining was furnished<span class="pagenum"><SPAN name="Page_19" id="Page_19">19</SPAN></span>
by the British when they blew up the important
post of Messines Ridge. This was
strongly held by the Germans and the only way
of dislodging the enemy was to blow off the top
of the ridge. Before work was started, geologists
were called upon to determine whether
or not the ground were suitable for mining-operations.
They picked out a spot where the
digging was good from the British side, but
where, if counter-mines were attempted from
the German side, quicksands would be encountered
and tunneling of any sort would be difficult.
The British sappers could, therefore, proceed
with comparative safety. The Germans
suspected that something of the sort was being
undertaken, but they found it very difficult to
dig counter-mines. However, one day their
suspicions were confirmed, when the whole top
of the hill was blown off, with a big loss of
German lives. In the assault that followed the
British captured the position and it was annexed
to the British lines.</p>
