Regiment: Royal Engineers (RE's)

The RE’s has been involved in every major conflict the British Army has fought and has ever since lived up to its Motto “Ubique” (“Everywhere”).
Royal Engineer tunnelling companies, nicknamed “the Moles”, were specialist units of the Corps of Royal Engineers within the British Army, formed to dig attacking tunnels under enemy lines during the First World War. They designed and built the frontline fortifications, creating cover for the infantry and positions for the artillery. It was in the hands of the technically skilled RE’s to develop responses to chemical and underground warfare.
The RE’s maintained the railways, roads, water supply, bridges and transport – allowing supplies to the armies. They operated the railways and inland waterways, maintained wireless, telephones and other signalling equipment, making sure communications existed. The Royal Engineers grew into a large and complex organisation, by the 1 August 1914, the RE consisted of 1056 officers and 10394 men of the regular army and Special Reserve, plus another 513 and 13127 respectively serving with the RE of the Territorial Force. The officers and men manned 26 coastal defence Fortress Companies (of which 15 were overseas), 7 Signal Companies, 2 Cable and Airline (signalling) Companies, 15 Field Companies, 3 Survey Companies, 2 Railway Companies, and miscellaneous other units. There were also 9 Depot companies carrying out training and administrative duties, as well as various Schools.
In 1915, in response to German mining of British trenches under the then static siege conditions of World War One, the corps formed its own tunnelling companies. Manned by experienced coal miners from across the country, they operated with great success until 1917, when after the fixed positions broke, they built deep dugouts such as the Vampire dugout to protect troops from heavy shelling. By 1 August 1917, it had grown to a total of 295668. It was twelve times bigger than the peacetime establishment.
