Who is a sapper you ask,
THE TORCH
The sapper is a dark, sombre man who looks where he is threading, and talks most of the time about box girders and conduit pipes. He is an essential part of the army, and is gloomingly aware of it.
His life is a misery; he is obliged to work hard and incessantly, both in and out of action, he is "delousing" mines, and blowing wire, and demolishing bridges and repairing others, sometimes the ones he has at some earlier stage himself demolished (enough to sour anyone), fixing roads and performing a hundred other hazardous and somewhat energetic chores.
Out of battle there is no respite. In a quiet area, there are always roads for him to repair or an airfield for him to build. His bulldozers are never quiet, and on top of everything, he will find that Division wants a handball court built, or concrete floors put in the tents, or a new drainage system put in to baffle the anopheles.
This in all has a depressing effect on the engineer. It tends to make him jaundiced towards his fellow man. He suspects the hearty greeting is the forerunner of a request for 2 bags of cement or that inquiry after his health is to ease the blow of asking for a work party.
So the sapper retires into himself, trusting only sappers. That is why, i think, they are so gregarious, it is unusual to see a lone sapper, unless he is a man of inflexible will. As a rule they believe in strenght in numbers.
They seek sanctuary from other units, generaly guarding themselves with a strip of bad road, or a barbed wire fence or a maze of bulldozer tracks. They hide their stores from prying eyes, which might be seeking the odd sheet of galvanized iron or a sheet of plywood. The sapper is not susceptible to flattery. He does not blush when told how wonderful his explosives are; he does not turn away shyly when informed he lays a pretty minefield.
It is impossible to win his heart that way. He knows there is no glamour in his job; no breathtaking activity or glory. He know that he is the drudgery of the army; the scullery work, the janitor's job.
But he has satisfaction- he knows that in every operation, in every sphere of war, the army leans on him
