Further evidence for a 14-16 hand () war horse is that it was a matter of pride to a knight to be able to vault onto his horse in full armour, without touching the stirrup. This arose not from vanity, but necessity: if unhorsed during battle, a knight would remain vulnerable if unable to mount by himself. In reality, of course, a wounded or weary knight might find it difficult, and rely on a vigilant squire to assist him. Incidentally, a knight's armour served in his favour in any fall. With his long hair twisted on his head to form a springy padding under his padded-linen hood, and his helm placed on top, he had head protection not dissimilar to a modern bicycle or equestrian helmet.
