Thomas Wilhelm, A Military Dictionary and Gazetteer
“ With men of ordinary firmness, a square should resist the charges of the heaviest horse. The formation is not new, for a Grecian Syntagma was a solid square of 16 men in every direction; but in modern warfare, the solid square having been found cumbrous, has been abandoned for the hollow square, with officers, horses, colors, etc., in the centre. The front rank kneels, and the two next stoop, which enables five ranks of men to maintain a rolling fire upon an advancing enemy, or to pour in a murderous volley at close quarters. ”
