Thomas Wilhelm, A Military Dictionary and Gazetteer
“ In military affairs, an uncertain number of men drawn out from several regiments or camps equally, to march or be employed as the general may think proper, whether on an attack, at a siege, or in parties to scour the country. A detachment of 2000 or 3000 men is a command for a general officer, 800 for a colonel, 500 for lieutenant-colonel, 200 or 300 for a major, 80 or 100 for a captain, 40 for a lieutenant, 12 for a sergeant, and 6 for a corporal. ”
