Ralph Willett Adye, The bombardier, and pocket gunner (1804)
“ In an offensive position it is absolutely necessary that the army [Pg 243] should not be too much confined by obstacles, but be at liberty to act in every direction; but in a defensive position, the fewer accessible points there are the better: and if the natural difficulties in front and flank are not sufficient to render an enemy’s attack dangerous, they must be increased by redoubts, intrenchments, abbatis, inundations, &c. ”
