Tunnelling and Mining on the Western Front

Tunnelling became one of the most dangerous specialist forms of warfare on the Western Front. Soldiers dug galleries beneath enemy trenches, listened for opposing miners, set explosive charges and worked in darkness under constant threat of collapse, gas, flooding and counter-mining.

The underground war mattered because it turned the front into a three-dimensional battlefield. Mines could destroy strongpoints or open assaults, but the work also placed small groups of men under extreme physical and psychological pressure, separated from the visible routines of trench life.

Birdsong is one of the best-known fictional treatments of this world, placing Stephen Wraysford among men working below the front line during the Somme fighting. The underground war involved sappers, miners, claustrophobia, trauma, engineering and the hidden labour behind major offensives.
