Sun boen haubert fist demander,[6] while of Bishop Odo he says:-- Un haubergeon aveit vestu De sor une chemise blanche. The fact that he mentions the tunic ('chemise blanche') seems to imply that it was seen beneath the hem of the haubergeon, which would not be the case with the long-skirted hauberk. Occasionally in illuminated manuscripts the hauberk is shown slit at the sides; but for what purpose it is difficult to imagine, for it would impede the wearer when walking and would make riding an impossibility. The defences of the leg, made of mail like the hauberk, seem to have been used, at first, only by the nobles, if the Bayeux Tapestry is taken as a guide. The common soldiers wore linen or leather swathings, sometimes studded with metal, but in appearance closely resembling the modern puttee. The upper portion of the leg was protected at a later period with Chaussons, while the defences from knee to foot were called Chausses. Wace mentions 'chauces de fer', but we must remember, as was noticed in the introduction, that Wace wrote some seventy years after the Conquest, and probably described the accoutrements worn at his own time. The Bayeux Tapestry is nearer the period, as far as we can date it with any correctness, but here we are hampered to some extent by the crude methods of the embroideress. The chaussons are not often shown in illuminations, for the long-skirted hauberk covers the leg to the knee; but the chausses appear in all pictorial and sculptured records of the period, made either of mail or of pourpointerie, that is fabric studded with metal. Towards the end of the thirteenth century the chaussons and chausses were made in one stocking-like form covering the foot; this is shown on Plate I, 8, 12. In the first of these illustrations only the front of the leg is covered, and the chausses are laced at the back. As the manufacture of mail progressed the whole of the wearer's person came to be protected by it. In addition to the coverings of the body we find continuations that protected arms and legs, and in course of time the neck and head were protected with a Coif or hood of mail, which is shown in use in Plate I, No. 12, and thrown back on the shoulders on No. 8. Although of no protective use, the Surcoat is so essentially part of the war equipment of the knight that it needs more than a passing notice. It first appears on Royal seals at the beginning of the thirteenth century, in the reign of King John. Some modern writers have suggested that it was first used in the Crusades to keep the sun off the mail; however this may be, we have written proof that it was of use in protecting the intricate fabric of chain armour from the wet, which by rusting the metal played havoc with its serviceability. It will be seen in different lengths in the figures on Plate I. In _The Avowynge of King Arthur_, stanza 39, we find--
