As if to complete the lesson so often taught in all wars, that discipline, care, and efficiency go hand in hand, when the army moved out from Opelousas, though but a fortnight later, a different state of things was seen. This must be ascribed to the fact that immediately after entering Opelousas the most stringent and careful orders were given for the regulation of future marches, and the punishment of stragglers and marauders. By these orders was provided for the first time a system adequate to their enforcement, and sufficiently elastic to meet without annoyance and difficulty all those cases, of hourly and even momentary occurrence in the movement of an army, that require officers or men to quit the column. In the rear of each regiment was posted a surgeon, without whose permission no sick man was allowed to fall out. In the rear of each brigade and division marched a detachment of cavalry, under the orders of the provost marshal of the brigade or division, charged with the duty of picking up as stragglers all men found out of the ranks without a written permit from the surgeon or the company commander. The vital importance of a strict enforcement of these arrangements was personally impressed upon the division and brigade commanders; yet this was not now necessary, for there were but few persons in the column of any rank that did not realize, in part at least, the evil consequences resulting from the irregular practices that had hitherto prevailed. Thus the march to the Red River was made rapidly and in order, and now for the first time the soldiers of the Nineteenth Army Corps marched with that swift and regulated movement of the column as a unit that was to be ever afterwards a source of comfort to the men, of satisfaction to their officers, and of just pride to every one belonging to the corps.
