Cavalry manoeuvres from John Vernon's The Young Horse-man (1644):

"The Motions for the Cavalrie are of foure kinds, as Facings, Doublings, Countermarchings, and Wheelings: the use of Facings is to make the Troop perfect, to be sodainly prepared for a Charge on either Flank or Reare, Doublings of Ranks or by half Files, or by Bringers up, serveth to strengthen the Front, Doubling the Files serveth to strengthen the Flanks, Countermarching serving to reduce the File-leaders into the place of the bringers up, that so the best men may be ready to receive the charge of the Enemy in the Reare."

First, however, you must get on your horse.
