T. W. J. Connolly, History of the Royal Sappers and Miners…
“ Enter now the 21-gun battery where four magazines are rebuilding. The sappers are quite at home raising the frames by the sickly beams of a feeble siege lamp; but look, a flying stone has just broken the horn and the wind has extinguished the flame. Yet, undiscouraged, the sappers work away by feeling the points and bases of their timbers. Go where you will, in battery, trench, or mine, a sapper is the centre of each party toiling at his hazardous vocation through the long dark night. ”
