ROAD TO WAR -
|“Clay Kickers” Dig the Somme &
Messines Mine Tunnels
|The Germans held the high ground directly in front
of the British and French front lines on many parts of the Somme.
Part of this was nicknamed by the British as “Mash Valley”,
which lay between the main Albert to Bapaume road, and all along
the Tara-Usna line and ran for many miles along the main front line.
They had an exceptionally good advantage and ideally positioned
with a clear view right across the valley as they could see for
miles. They also held many strong points, bunkers and strategic
positions on the ridges that overlooked this distant area. Their
positions showered down incessant artillery and machine-gun fire
on the British infantry far below in the trenches, holding those
on lower slopes to ransom or death. They were prepared, ready and
waiting to wipe out thousands of British and Commonwealth, French
and Belgian infantry troops that they knew would soon advance upon
them. They realized that soon there was to become a major offensive
Both front lines was on a 24 hour vigil, especially at night, in
case of a suspected attack by the enemy would prevail, hence both
sides used Verey (very) lights / flares which when fired would light
up the whole of the surrounding area …as daylight, to see
if the enemy was making a night time attack on them.
In some places the opposing forces
were only between 500 - 800 or more yards apart, so easy targets
for each side by using snipers with rifles, using their trench
periscopes they could see each other very clearly and pick their
The German and British Armies had already used underground technology
and miners to dig tunnels to blow small mines under each other’s
main positions since the early beginnings of the war, these had
been sometimes successful, but far larger mines were planned for
the bigger offensives to come. Initially hundreds of miners had
already been recruited into the British Army in 1914,
of the Tara-Usna line,across from
“Mash Valley” to near-by German positions
(2013 C/R-I.R. Bridle)
| as well as in the German Army, as both opposing forces
soon realized that the advantages of this newly conceived “Underground
Warfare” in which tens of thousands could be killed in massive
explosions, rather than lose valuable soldiers facing enemy machine
– gun and artillery fire. The massive tasks involved in digging
these tunnels literally employed tens of thousands of men to accomplish
this specially assigned work who would soon arrive from distant
shores to the Western Front. It would take many months of weary
tiring, back breaking and sweating work. These men were exceptionally
hard working, brave and devoted to their occupation, as difficult
and tiresome as it became. Many more thousands of British and Commonwealth
miners were soon to follow, as these would be the ones to dig miles
of underground tunnels from the British lines directly under the
German strong points, at the appointed places directed by High Command.
These mines were planned to be blown prior to a major infantry attack.
The British Generals still firmly believed that all the Germans
would be dead, once the huge detonation by the mines had been blown,
coupled with the preceding one week long barrage of British and
French artillery guns along the Somme front line.
By early 1916, over 25, 000 miners from Britain and the Commonwealth,
Australia and Canada had been employed. Each crew worked 8 hour
shifts, as the tunnel progressed farther along, they would have
to walk this distance from the entrance to the clay face to start
digging again where the previous crews left off, which could be
anything up hundreds, then thousands of yards, then many miles,
until they reached their final destination where the chamber holding
the colossal amounts of explosives would eventually be stored, right
under the designated German strong points. The very long and arduous
digging was to take many months of weary tiring and sweating work,
these men were exceptionally hard working, brave and devoted to
their work, as difficult and tiresome as it became.
The first examples of the planned massive mine explosions under
the enemy lines was desperately hoped it would accomplish the desired
effect, possibly by destroying the enemy and bring the War to an
end, at least in their naïve thinking this is what they firmly
believed and trusted in. So three top priority and major targets
were chosen by the British High Command. There were a total of 8
large mines and eleven smaller ones planned, that would all be detonated
at the same time, primed and ready to be blown on the morning of
1st July 1916, just before the “Battle of the Somme”
offensive started. This every effort was to destroy the German barbed
wire defenses, fortified positions and artillery guns....and kill
all the enemy!
Firstly the tunnel entrance would have to be dug down to an angled
depth of about 60feet/20mts for the steps / stairs to be supported
and constructed, depending on the soil/ sand / clay conditions,
or they may have to dig much deeper until finding solid enough ground.
The solid wood entrance to support it and the stairs were installed,
then they would branch out on a straight level in the direction
designated, digging further towards the plotted firing chamber.
It was necessary to move the hundreds of tons of spoiled earth out
of every tunnel by wheelbarrow, or big steel barrows on rails as
used in coal mines, then hauled in buckets or bags up the stairs
and distributed along the front lines. The walls and floor had to
be shored up with thick oak posts and wooden planks to hold up the
intense weight and to prevent cave-ins occurring and in weaker areas
iron girders were placed in weaker positions
When there was a cave-in, and there were many
serious issues to confront, they would all be blocked off from
the tunnel entrance usually due to a sand barrier or the weeks
of heavy rain soaking down through the soil and weakening the
earth above them and flooding the tunnel. It had to be shored
up and the water manually pumped out exceptionally fast, then
duck boards placed on the floor of the tunnel to keep the soldier’s
feet as dry as possible. Many would suffer an agonizing death
by being buried alive or drowned as hundreds of men were killed
and injured due to the severity of the cave-ins and potentially
hazardous conditions. It could take up to 12 hours or longer to
get each injured man on a stretcher, or dragged back by hand to
the entrance of the tunnel for medical assistance, then transported
to the base hospital for treatment….many, many never made
it! But the miners: the newly nick- named “Clay Kickers”
that had a technique all of their own, it was an incredibly fast
and very effective, they sat on a wooden type angled chair and
partly laid back on a cross piece of wood, the spade was fitted
into a wooden frame, and using their leg’s would push the
spade into the clay with their feet, which would be dug out in
large amounts ready to be barrowed away. A canary in a cage was
always taken down with them as used in coal mines to detect any
harmful gases that could build-up, or attempts by the Germans
to use poison gas on them.
Each “Clay Kicker” was paid 6/- a day, a fortune in
those days, for their very long tiring hours of extreme hard manual
“Clay-Kickers” digging a tunnel,
and artists impressions of the “Special Chair” apparatus
they used, which proved fast and efficient.
Once these tired weary men had completed
their shift they would have to walk all the miles back, then up
the steps out into the fresh air, they then had to run the gauntlet
of German artillery and machine-gun fire as they rushed back to
the rear trenches, for food, rest and a long awaited sleep.
|Work had started many months before on the three tunnels
that were to blow the three mines around La Boisselle, one mine
in particular, was named Lochnagar by the 51st Highland Division,
who had held the line previously and called their own trench, by
the same name, hence the crater was later named. The next part of
this backbreaking work for this one mine alone was that the soldiers
had to convey the nearly 60, 000lbs (25 tons) of high-explosive
gun-cotton to the end of the tunnel in the detonation chamber at
La Boisselle and place them accordingly, two charges were placed
at 60ft apart and approximately 50ft from the surface.
The tunnels were supposed to be “top secret” whilst
being dug and under construction, but it was found that in some
cases as both the British and German tunnels suddenly converged
and were so close together, as the British were digging towards
the German lines, and the German were heading for the British strong
points, they could hear the men talking and spades digging the hard
clay. Both sides would use many different listening devices, like
a long hollow copper tube with a bell shaped end fitted in the ear,
or a doctor’s stethoscope, also electronic devices. They could
then hear if the enemy was digging close by or not. Even a sneeze
or cough could be heard many dozens of yards away by the enemy,
the men were ordered to "Keep Quiet" as they got nearer
their final objective. If they heard any noise or inclination of
being so close to the enemy…all work and noise would “Stop”
…they just had to wait and listen… as all the men waited
in fear that the enemy from either side would suddenly break through
into their tunnels...then all "Hell" would erupt against
On many occasions they would suddenly break through into each other’s
tunnels, hurl grenades through the gap wait for the explosion, then
dozens of men poured through shooting at everyone. In these bloody
underground battles soldiers would fight in any brutal way possible
with bayonets, knives, spades (one side sharpened like a razor,
which would cut a man’s neck down to his chest in one blow)
knuckle dusters were used or any implement that could be grabbed
quickly, with the eventuality using their own fists to kill the
enemy, they were so vicious that these could carry on for a long
time until all the enemy on either side were dead or taken as prisoners.
This huge amount of explosive would usually come in 25 lb bags,
for this mine alone at Lochnagar, it would take a total 2, 400 x
25lb bags, which needed to be carefully hauled down the steep shafts
and along the thousands of yards/ miles to the end of the tunnel
by wheelbarrow, coal trucks on rails, or carried by hand. Once all
the bags were in position the Royal Engineers took control, confirming
that main connections, electronic devices for the detonation were
complete, they then ran the firing cables all the way back to the
British lines. All was secured, then in the safety of the firing
bunker sat and waited for the final signal to press the plunger…and
send the enemy to “Hell”
After the seven day continues bombardment of the German front lines
on the Somme, the day came when the mines would be finally blown.
On the sunny morning of 1st July, 1916, this mine at Lochnagar was
detonated at 07.28 a.m. in the morning, shaking the earth for miles.
The terrific blast roared upwards destroying some of the enemy’s
deep defences and strong points. The truth of the massive mines
being blown was soon evident, which stunned the High Command watching
a mile or so behind the front line, for they were the ones who declared
initially to all the men that “All the enemy would be destroyed”.
The final detonation of the mines succeeded in killing thousands
of Germans, but their very well built deep underground dugouts all
along the front line were unaffected by the explosion, therefore
giving valuable time for the Germans to reach the top and set-up
their machine guns, in and around the crater itself…and wait
for the enemy, who they knew would soon advance upon them!
As the many thousands of first line of British infantry troops advanced,
and within only minutes after “going over the top” the
enemy opened fire on the casually walking men before them. They
were cruelly massacred, horrifically wounded by the German machine-gunners
and artillery fire. It had actually failed in part in destroying
the barbed wire defences running hundreds of yards deep, this is
what the Generals had hoped for in the seven day bombardment, but
despite the amount of worked entailed with the artillery barrage
and to create these fearsome underground explosions, the eventual
disappointment as the day progressed, was that they faced an horrendous
defeat, then soon to hear of the tremendous losses encountered to
the British Army in just a few hours... was horrific!
Although a massacre followed for the British and Allied forces,
after many ferocious battles that day, only a few enemy front line
defences fell into British hands, but hundreds of seriously injured
British soldiers shot and wounded by shrapnel and machine-gun fire,
found cover in the crater holes, hundreds if not thousands bled
to death before they could be rescued in agony from head, chest,
stomach and leg wounds, as the days passed after the British had
secured the front line a priest was called to perform burial rites
on those dead and dying….Who were Many!
Crater - Blown on 1st July1916, it is estimated that over 10,
000 Germans were killed in this explosion alone. The blast was
so loud it was heard in Southern England, to show how deep this
crater is, can you see the poppy wreath at the bottom center right

|Private George Nugent …1306…22nd Battalion,
Northumberland Fusiliers, missing in action since 1st July1916,
but 83 years later his body was found under the earth alongside
the crater rim, by a man walking his dog.
For all those years his body was lost to his beloved family who
had no place of burial to visit, like the other tens of thousands
missing in action.
But now he lies buried with his friends, comrades and fellow soldiers
in a local cemetery.
It was indeed, a very moving service, tears were shed by many, sadness
was in their eyes for all those lost in death, only to be Remembered
by a Gravestone or a Memorial.
But to those German and British soldiers who were tragically “blown
to pieces” by this explosion and the enemy shelling…
Have no known grave.
Today this crater…still named Lochnagar...is privately owned,
it was purchased in 1979 by Mr Richard Dunning of England, and remains…Thanks
to Him and his Faithful Friends, a permanent memorial, a tribute,
and a memory to the thousands who lie asleep in death under the
clear blue skies of France that were killed here.
|The tens of thousands of British and Commonwealth
troops who were killed all along this part of the front line are
remembered at the Thiepval Memorial to the Missing, just a few kilometers
away, close by this crater, with over
73, 412 names engraved on its walls who were killed in 1916 –
1917, and just behind this is the cemetery with equal numbers as

|Tens of thousands of their loved ones travelled here
to find the graves after “The Great War” had concluded,
for those they had lost, always searching, looking in despair and
desperation for the “Loved Ones” that said Goodbye to
them months or years before. From all nations they came to try at
whatever the cost to find them and ask...”Where is My Boy
They were frantic in their exploration to find their loved ones,
many killed in this “Great War” had no known graves,
not until years/ many years later did some …at last find and
to stand and look down on the cold stone cross, marble plaque and
see their Sons, Fathers, Brothers name...etched in stone, their
grave where they now lie...under the skies of France & Belgium.
Their heart’s full of tears, their dreams lost, their hopes
gone forever that they would see these precious ones again...They
proudly left flowers and a prayer, wiped their eyes and said with
the deepest grief in their Heart & Soul…Goodbye!
|The Germans held many strategic high points which
had been fought and won in earlier battles they ran in a large arc
right in front of the British lines. It was these that the British
wanted back to give them the edge for once over the enemy. Many
battles continued to be fought all along the front line in a hope
to regain these lost positions, with a fast growing casualty list
of thousands being killed on both sides every day.
Early in December 1914, the Messiness Ridge was captured and under
German control, they established it as a strategic observation and
command post, it overlooked the valley giving an excellent view
towards the Ypres Salient, where all military enemy activity could
be clearly seen.
Operations were put into action to plant twenty-four mines underneath
the German held front line and explode them all in unison, in the
hope of a total destruction of all the enemy held positions. This
massive task was undeniably dangerous and time consuming, but never
the less the plans for the tunnels were drawn up, and work soon
Preparations were under way to try and regain the summit for the
British, it took nearly two years of backbreaking work by over 10,
000 men from the British, Australian, and Canadian Tunneling Companies
to achieve. This in itself was a major achievement like the many
other tunnels that were dug.

During February 1915, the Special Mining Squads were relatively
rare and in the process of being formed up into Tunneling Companies,
in April they were amalgamated and reinforced by new recruits to
make up a new 171st Tunneling Company.
The 171st would eventually be one of many Tunneling Companies recruited
here as “Clay Kickers”…The names of a few of the
men that dug these vast tunnels were…Fred Francis, Bert Ferns,
George Louth, Albert Marshall, Ted Rimmer, Donald Hodge, John Laiser,
and Captain Norman Dillon, forming the 170th, 172nd, 178th Tunneling
This area was notorious for the different layers of earth, on top
was loam, underneath was over 20feet/ 7metres of firm dry sand which
separated the hard blue clay, below that was 7feet/ 2metres of quicksand,
in all it would be very difficult and dangerous for the Tunneling
Companies who were about to start the tunnels in that area, digging
towards the German lines.
As early as August 1915, plans were already underway to dig the
many underground tunnels towards Messines-Wytschaete Ridge in Belgium,
which formed a large arc from Hill 60 to the east of Ploegsteert
The deep mining for the two tunnels, and mines to be laid began
in August 1915 they were about 250 yards behind the British frontline.
This was carried out by the 175th Tunneling Company, from an entrance
by the railway cutting on Hill 60. These two tunnels were dug to
a depth of 90ft / 30metres from the surface.
|In April 1916, the 3rd Canadian Tunneling Company
took over, and by July 1916 the massive gallery was finished under
Hill 60. The high explosive consisted of a total of 53, 500lb, which
meant that 2, 140 x 25lb bags would have to be transported along
the tunnel to the chamber and prepared.

|In October 1916, another gallery was completed under
the Caterpillar as it was named, and 70, 000lb consisting of 2,
800 x 25lb bags of high explosive charges was placed in position,
that too was prepared and ready to blow.
By November 1916, the 1st Australian Tunneling Company continued
with the upkeep of the mine, but endless above and underground fighting
continued, every effort was made to stop the Germans discovering
the two mines already placed there.
These two mines were the most northerly of the planned chain of
24 mines that were being dug in different places by the British,
all to be detonated at once all the way along right up to Messines
All the mines along the line had been dug and the tens of thousands
of high explosives bags of charges loaded in place, the detonators
had been fixed, the firing cables run far back down the miles of
tunnels to the Command Posts. Everything was planned for the attack,
the infantry stood by, the artillery guns loaded, all waited in
anticipation …for the signal to “Blow”.
At 03.10am precisely on 7th June
1917, the plunger was pressed and a series of tremendous explosions
all along the German front line erupted and rocked the earth for
miles just like an earthquake, the shock was so tremendous that
it was felt in southern England!
(Left) Hill 60 after the mine was blown and re-captured(C/R-I.
|Immediately the mines blew and before the dust settled,
the entire might of the Second Armies two thousand artillery guns
opened fire on the German lines in a three pronged barrage, pounding
the enemy and earth into an unrecognizable crater filled moonscape!
As nine Divisions of infantry moved towards the blown craters they
found thousands of Germans had been killed outright, hundreds of
others were so stunned they were taken prisoner, many German strong
points were taken after fierce fighting along the line of the exploding
mines. Finally Messines Ridge was back in British hands. (Only nineteen
of the twenty four mines placed actually exploded)
At the other end of the chain, the British finally regained Hill
60 after a successful infantry attack by the 69th and 70th Yorkshire
Battalion Division, their attack had very few casualties.
After the two massive explosions the Hill 60 crater was vast being
60ft deep and 260ft wide, the Caterpillar crater was even bigger
at 90ft deep and a 334ft wide.
The 204th German Division who held the hill, had
10 officers and 677 men killed in the blast.
During the storming of Hill 60 after it had blown, many awards
were given out for gallantry.

Painstaking as they were to dig,
and horrific in their destruction, they seemed to do the job of
killing the enemy and gain control of vantage points in the necessity
to try and bring this war to an end, much to the delight of the
Generals and High Command who were always determined to push,
push forwards despite the terrible losses!
Even today you can follow the line of the nineteen mines that
were blown in the big arc, most are small others far bigger, now
mostly are ponds full of water and used by farmers.
St Eloi is remembered for being the place where the very first
mine of the “Great War” was blown by the Germans in
March 1915, this part of the front line was constantly being attacked
and counter attacked, taken and retaken many times, with very
heavy losses, so the necessary planning to use mines here was
During the next 12 months the British blew 13 mines and 29 Camouflet’s,
the Germans blew 20 mines and 2 Camouflet’s on different
occasions under each other’s opposing front lines and strong
positions, causing much destruction with many being killed on
Six British mines were detonated here on 27th March 1916, under
the German front line, consisting of a total of
73, 000lbs of high-explosives, nearly 3, 000 x 25 lb bags, which
were hauled along the tunnels to the detonation chamber.
During the massive combined mine explosions that heralded the
Messines Ridge artillery and infantry attack, one of three mines
to be blown here was the largest of all.
The total amount was a massive 95, 600lbs of ammonal, which comprised
of 3, 864 x 25lb bags of the high explosive, these bags had to
be transferred along the underground tunnel to the detonation
chamber, and as can be imagined a phenomenal amount of manpower
was necessary to accomplish this task.
This crater after the detonation was one of the biggest seen on
the Western Front.
Of the twenty-four mines dug and tunneled to lay the massive amount
of ammonal charges, it is estimated that just over 1, 000, 000lbs,
of high explosives were used. Which amounted to a colossal 40,
000 x 25lb bags, that had to be transported to the entrance of
each tunnel, by hand, horse and carts, then barrowed along hundreds
of yards if not miles to the detonation chambers.
It is estimated that during the “blowing” of the nineteen
mines along the front line towards Messines Ridge that approximately
25, 000 Germans were killed.
Some of the other mines that were blown all along the front line
at different times were named by the British as… Tree Crater,
Caterpillar Crater, Hooge Crater, Maedelstede Farm Crater, High
Wood Crater, Battle Wood Crater (there are a few in the woods
here from the 1915-1916 explosions) St Eloi Crater, to name but
All over the battlefields you can see large and small crater holes
where hundreds of mines were blown both by the British and Germans
since the near outset of the start of “The Great War”
