Sapper
Soldiers of No 2 Field Company, Bombay Sappers and Miners on duty in China in 1900. The mule carries the tools required for field engineering tasks.
A sapper, in the sense first used by the Assyrian Army in the early 7th Century BC[citation needed], was one who excavated trenches under defensive fire to advance a besieging army's position in relation to the works of an attacked fortification, which was referred to as sapping the enemy fortifications.
Saps were excavated by brigades of trained sappers or instructed troops. When an army was defending a fortress with cannon, they had an obvious height and therefore range advantage over the attacker's own guns. The attacking army's artillery had to be brought forward, under fire, so as to facilitate effective counter-battery fire.
This was achieved by digging what the French termed a 'Sappe'. Using techniques developed and perfected by Vauban, the sapeurs (sappers) began the trench at such an angle so as to avoid enemy fire 'enfilading' (passing directly along) the sappe. As they pressed forward, a position was prepared from which cannon could suppress the defenders on the bastions. The sappers would then change the course of their trench, zig-zagging their way toward the fortress wall.
Each leg brought the attacker's artillery closer and closer until (hopefully) the besieged cannon would be sufficiently suppressed for the attackers to breach the walls with their artillery. Broadly speaking, sappers were originally experts at demolishing or otherwise overcoming or bypassing fortification systems.
Miner
An additional term applied to sappers of the British Indian Army was 'miner'. The native engineer corps were referred to as 'sappers and miners', as for example, the Royal Bombay Sappers and Miners. The term arose from a task done by sappers to further the battle after saps were dug. The saps permitted cannon to be brought into firing range of the besieged fort and its cannon, but often the cannon themselves were unable to breach the fort walls. The engineers would dig a tunnel from the forward-most sap up to and under the fort wall, then place a charge of gunpowder and ignite it, causing a tremendous explosion which would destroy the wall and permit attacking infantry to close with the enemy. This was dangerous work, often lethal to the sappers, and was vehemently resisted by the besieged enemy. Since the two tasks went hand in hand and were done by the same troops, native Indian engineer corps came to be called 'sappers and miners'.
