In 2010, as part of a multi disciplinary contribution to the 2014-18 commemoration of the First World War the Durand Group, one of the world's leading authorities on subterranean military activity, chose the Loos Salient as its key Western Front area of study for an ongoing underground investigative research and interpretation programme.

Why have we done this?

What many people don't really understand about the First World War, for all its emphasis on trenches, mud and casualties, is the hidden face of battle; they tend only to think of what they can see. But these now dwindling scars on the landscape are simply a visible manifestation of a much more complex engineering war that, by the end of 1915, had moved almost completely underground. The infantry lived underground. They moved to and from the rear lines underground. Deeper still below them were the tunnellers, who fought the enemy, sometimes hand-to-hand, underground.

The Durand Group's mission is to fully explain to the general public the fundamental engineering concepts of LIVING, MOVING and FIGHTING, but in an underground context, together with its unique significance during the First World War.

What makes the Loos Salient particularly significant for the Durand Group?

Firstly the it has all the hallmarks of a mature conflict archaeology site - potential enough to paint a complete picture of the underground war evolving as it did from a relatively ad hoc, tactical response to early German initiatives in 1915, through gradual dominance of the deep mine fighting during 1916, to the strategic defence-in-depth infantry tunnel and subway systems that evolved during later operations of 1917-18 with their almost medieval measures and countermeasures.

Secondly, the Group's continued investigative work since 2010 commands much respect within the local communities - the farmers, landowners, local officials and historians - who have fully endorsed our work thus far, have to live with the legacy of the underground war on a day to day basis and who have looked to the Group to help interpret the story further over recent commemorations.

 Thirdly, perhaps uniquely, in the untold story of the battles for the Loos Salient, our story involves Canadian Infantry under British Army command utilising Australian tunnelling expertise against their German counterparts in liberation of French communities. As such it is a truly international story.

Engineering the Loos Salient 1915-2018 (under construction)

Much ignored by both press and public and not featuring at all in the government's official commemorative itinerary the Battle of Loos and its aftermath provides the perfect canvas for explaining a most ancient concept

of warfare within a 20th century military environment - the Siege!

The war correspondent Phillip Gibbs described the region as:

"..the Black Country of France, scattered with mining villages in which every house was a machine-gun fort, with slag heaps and pit-heads which were formidable redoubts, with trenches and barbed wire and brick-stacks, and quarries, organized for defence in siege-warfare, cavalry might as well have ridden through hell with hope of "exploiting" success.."

Located between Bethune in the north and the City of lens to the south in the Pas de Calais region of France, Loos-en-Gohelle is today a sleepy town. It wasn't so sleepy in 1915 as the British prepared for their most ambitious battle to date on the Western Front. The actual Battle of Loos, fought between 25th September and 13th October 1915, achieved limited success in terms of ground taken but did not fulfil its primary objectives - to aid break through of the Artois, re-establish a war of movement and in the process take re-possession of several of the important mining assets in the region including Lens. What it did do was to establish a vulnerable salient into which the Germans could direct all their artillery resources with impunity for the next two years,reducing many of the local communities  to rubble and destroying what remaining mining infrastructure  still existed. It also inflicted 60,000 casualties in three weeks on a  British Army that could ill afford the losses among them Jack Kipling, son of Rudyard and Felix Bowes Lyon, brother of the Queen Mother.  It is also significant for one other key reason: It resulted in the eventual sacking of the BEF Commander in Chief, Field Marshal Sir John French and the promotion of his immediate subordinate General Sir Douglas Haig.

From a strategic point of view the Loos Salient became somewhat of a backwater - both sides gradually and  reluctantly accepting that the war would probably not be won or lost there. It therefore became an ideal nursery for reintroducing those medieval tactics that characterised so many earlier conflicts in history - the art of siege warfare - and it did so for three years from the end of 1915 until the armistice in 1918. As the lines stabilised specialised tunnelling companies were deployed and mining sectors were established, from south to north in the Salient - Double Crassier, Copse, Hill 70, Chalk Pit, Hulluch/St Elie, Hairpin, Hohenzollern as far north as Givenchy and the Le Bassée canal.Here men lived, moved and fought each Here men lived, moved and fought each other incessantly for almost four years burrowing in a myriad of dugouts, subways and tunnels - a troglodyte world so extensive that some of the underground installations could be seen as communities in their own right:

"To the north of Lens near Hulluch, where I went through the workings with Sanderson, the whole defence of the front appears to be underground. The infantry garrison lives underground, trench mortars and their crews are underground. The machine guns are underground and for a mile behind the front line the communication trenches are underground. The light railway delivers stores to the gun emplacements by an even lighter railway - underground!"

Charles Bean, Australian Official Historian of the Great War

After three years of research and investigation the Durand Group can now confirm that it has gained unprecedented access into the Deep Deep (DD) levels of the 'Copse' mining system south of the village of Loos-en-Gohelle  - to a depth of thirty metres and an extent of over a kilometre. It has also recently accessed the whole of the Hulluch/St Elie tunnel system further north - and is now in a unique position to continue interpreting this and other mining sectors in the immediate vicinity. Work in the last 12 months has move further north - to the tunnels of the HAIRPIN and QUARRIES  sectors. Here we have accessed both the British AND German lateral and fighting tunnels.
