and archers or crossbowmen, with about equal numbers of cavalry and archers and the foot soldiers equal in number to the other two types combined. Later lists of companions of William the Conqueror are extant, but most are padded with extra names; only about 35 named individuals can be reliably identified as having been with William at Hastings. The main armour used was chainmail hauberks, usually knee-length, with slits to allow riding, some with sleeves to the elbows. Some hauberks may have been made of scales attached to a tunic, with the scales made of metal, horn or hardened leather. Headgear was usually a conical metal helmet with a band of metal extending down to protect the nose. Horsemen and infantry carried shields. The infantryman's shield was usually round and made of wood, with reinforcement of metal. Horsemen had changed to a kite-shaped shield and were usually armed with a lance. The couched lance, carried tucked against the body under the right arm, was a relatively new refinement and was probably not used at Hastings; the terrain was unfavourable for long cavalry charges. Both the infantry and cavalry usually fought with a straight sword, long and double-edged. The infantry could also use javelins and long spears. Some of the cavalry may have used a mace instead of a sword. Archers would have used a self bow or a crossbow, and most would not have had armour. Harold moves south After defeating his brother Tostig and Harald Hardrada in the north, Harold left much of his forces in the north, including Morcar and Edwin, and marched the rest of his army south to deal with the threatened Norman invasion. It is unclear when Harold learned of William's landing, but it was probably while he was travelling south. Harold stopped in London, and was there for about a week before Hastings, so it is likely that he spent about a week on his march south, averaging about per day, for the approximately . Harold camped at Caldbec Hill on the night of 13 October, near what was described as a "hoar-apple tree". This location was about from William's castle at Hastings. Some of the early contemporary French accounts mention an emissary or emissaries sent by Harold to William, which is likely. Nothing came of these efforts. Although Harold attempted to surprise the Normans, William's scouts reported the English arrival to the duke.
