Plate armour
At Agincourt: Full plate kept many arrows out but wore the French men-at-arms down across the soaked, ploughed field and in the crush at the English line.
By 1415 a man-at-arms could be enclosed head to foot in steel. It kept most arrows out, but at Agincourt the French men-at-arms advanced across soaked, ploughed ground under arrow fire and arrived exhausted, packed so tightly that many could not lift their weapons. At Poitiers in 1356 armour was still transitional: mail, coats of plates and growing plate limb defences.
