Old Humphrey, Soldiers and Sailors
“ The battle array generally consists of three lines, the front, the rear, and the reserve. An attacking army is generally divided into three parts, the main body, and the two wings. And the battle array is formed by dividing each of these into three lines, the front, the rear, and the reserve; the artillery is divided along the front of the first line, and the treasure, provision, and baggage, are removed to a safe place before the engagement. ”
