What to read after Battle Of Poitiers, September 19, 1356?

In the simulation of the battle of Poitiers we will take into account that the center of gravity of both maneuvers (defensive and offensive) was the support on obstacles - natural and / or artificial -, which in the case of the English compensated their numerical inferiority; and the possibility of maneuvers looking for gaps in the defensive device should the French remain on horseback. As for the French infantry, we will understand that this force led by the constable Brienne, before the king, compensated for the smaller quantity (3 of the 15-20 thousand men) with a better quality. Considering the English historical device maintained, a Cuneus battle order will be employed by the French, combining the clash of an infantry over the center with subsequent flanking and encirclement by the cavalry.
