Cap badge Royal Engineers (RE)

The Royal Engineers trace their origins back to the military engineers brought to England by William the Conqueror, specifically Bishop Gundulf of Rochester Cathedral, and claim over 900 years of unbroken service to the crown. Engineers have always served in the armies of the Crown; however, the origins of the modern corps, along with those of the Royal Artillery, lie in the Board of Ordnance established in the 15th century.^[2]

In Woolwich in 1716, the Board formed the Royal Regiment of Artillery and established a Corps of Engineers, consisting entirely of commissioned officers. The manual work was done by the Artificer Companies, made up of contracted civilian artisans and labourers. In 1782, a Soldier Artificer Company was established for service in Gibraltar, the first instance of non-commissioned military engineers. In 1787, the Corps of Engineers was granted the Royal prefix and adopted its current name and in the same year a Corps of Royal Military Artificers was formed, consisting of non-commissioned officers and privates, to be officered by the RE. Ten years later the Gibraltar company, which had remained separate, was absorbed and in 1812 the name was changed to the Corps of Royal Sappers and Miners.

The Corps has no battle honours. In 1832, the regimental motto, Ubique Quo Fas Et Gloria Ducunt ("Everywhere That Right And Glory Lead"; in Latin fas implies "sacred duty"), was granted. The motto signified that the Corps had seen action in all the major conflicts of the British Army and almost all of the minor ones as well.

In 1855 the Board of Ordnance was abolished and authority over the Royal Engineers, Royal Sappers and Miners and Royal Artillery was transferred to the Commander-in-Chief of the Forces, thus uniting them with the rest of the Army. The following year, the Royal Engineers and Royal Sappers and Miners became a unified corps as the Corps of Royal Engineers and their headquarters were moved from the Royal Arsenal, Woolwich, to Chatham, Kent.

In 1911 the Corps formed its Air Battalion, the first flying unit of the British Armed Forces. The Air Battalion was the forerunner of the Royal Flying Corps and Royal Air Force.

In 1915, in response to German mining of British trenches under the then static siege conditions of the First World War, 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.

Before the Second World War, Royal Engineers recruits were required to be at least 5 feet 4 inches tall (5 feet 2 inches for the Mounted Branch). They initially enlisted for six years with the colours and a further six years with the reserve or four years and eight years. Unlike most corps and regiments, in which the upper age limit was 25, men could enlist in the Royal Engineers up to 35 years of age. They trained at the Royal Engineers Depot in Chatham or the RE Mounted Depot at Aldershot.
