These weapons were always costly to get and heavy to bear, such as the brunia or hauberk of the Carlovingian Era, the coat of mail, which prevailed during the Crusades, and lastly the plate armor introduced in the fourteenth century.
HORSES

No knight was thought to be properly equipped without at least three horses:

• the battle horse, or dexterarius, which was led by hand, and used only for the onset (hence the saying, "to mount one's high horse"),

• a second horse, palfrey or courser, for the route, and

• the pack-horse for the luggage.

ATTENDANTS

• one to conduct the horses,
• another to bear the heaviest weapons, particularly the shield or escutcheon (scutum, hence scutarius, French escuyer, esquire);
• still another to aid his master to mount his battle horse or to raise him if dismounted;
• a fourth to guard prisoners, chiefly those of quality, for whom a high ransom was expected.

These attendants, who were of low condition, were not to be confounded with the armed retainers, who formed the escort of a knight. From the thirteenth century the squires also went armed and mounted and, passing from one grade to the other, were raised finally to knighthood. 

FLAGS

Banners were also a distinctive mark of chivalry. They were attached to, and carried on, the lance.
