Besides these three officers, each Troop of Reiters had a _Wachmeister_, and each Company of Landsknechts a _Feldwebel_, terms still retained in Germany with the meaning of _Sergeant_. This officer was of great importance in the unit, as he was charged with its drills in peace, and with its manœuvres in battle, when the other officers were in front fighting, and could not watch the men. As the Sergeant had to give orders in action, he became also responsible for Orders at all times, so that he was virtually a kind of Adjutant to the unit. In battle the Infantry Sergeant had to run up and down the Company to supervise its movements; he, therefore, could not well be encumbered with the long pike, but retained the earlier halberd, which survived as the special arm of the Sergeant of Infantry in England down to 1829. There was similarly in the _Regiment_ a corresponding officer, the _Sergeant-Major_, later styled simply the _Major_, as he still is. He was practically a Staff Officer, or Adjutant, to the Colonel, exactly as the _Sergeant_ was to the Captain. He issued the Colonel’s orders to the Sergeants, and was responsible for the drill of the Regiment, and its manœuvres in battle. He was therefore mounted, even in the Infantry Regiment, like our Adjutant to-day, in order that he might move rapidly up and down the Regiment, to superintend its movements and give orders to the Sergeants of the various Companies. There was also in the Reiters a _Quarter-Master_, the _Fourier_ (as the French still style him), with a subordinate (now the Quarter-Master-Sergeant). His duties were to provide _quarters_, and, as the men had to be fed in these quarters, he became charged in addition with _subsistence_, exactly as is our Quarter-Master to-day. In old times the Quarter-Master was also responsible for _reconnaissance_, which was no doubt due to the fact that, having to precede the troops on the march, so as to provide quarters for them that evening, it fell to him to decide on the correct route, and he had, therefore, to reconnoitre to the front. What are now the Staff duties of reconnaissance and directing marches became thus associated with the Quarter-Master of each unit, and afterwards with the corresponding officer, the Quarter-Master-General of the whole army. Therefore, down to a few years ago, the Q.M.G. was charged with all Staff work connected with marches, routes, reconnaissance, and information--a curious survival through four centuries of the organization of the Reiters.
