Battle Of Créçy, August 26, 1346 [PDF ebook] 

Although the information of the prior recognition of the English strong position had not altered the count of Alençon s willingness to attack, King Philip in verifying his blatant failure could have halted this, let s call it, forceful recognition, and taken an offensive device for the attacks in the early hours of the next day. When a typical Byzantine (or Double Perpendicular with forward pressure combined with flank attacks) would then be employed, that is, a force frontally threatened the enemy formation by fixing it, especially if it were a solid infantry block, but without engaging decisively; then other forces sought to flank and / or engage the enemy device.
