The military force of the Anglo-Saxons consisted principally of infantry. The chivalrous Thanes, noblemen and men of property, fought on horseback, and armed and mounted a portion of their retainers. The infantry consisted of two classes--heavy and light; the former carried large shields, and were armed with spikes and long broad-swords, and spears; while the latter were armed with swords and spears only. There were also men armed with clubs, and others with battle-axes and javelins. The Saxon law esteemed every man a soldier, unless incapacitated by age or physical weakness, and he was regularly trained in the use of arms. The head of a family was the leader of all the capable males in that family. The line of battle of our Saxon forefathers was simple in the extreme. The Royal standard stood in the centre; around it gathered the mounted Thanes, while the infantry stood in the foremost ranks to bear the brunt of the fighting. The weapons carried by the infantry during several reigns succeeding the Conquest were bows and arrows, half-pikes, swords, and daggers. Armour was worn on the head and body, and in course of time the practice became general, and men were so completely encased in steel that it was almost impossible to slay them. But the introduction of gunpowder for purposes of war, in the early part of the fourteenth century, produced a change in the arms of both mounted and dismounted soldiers. Bows and arrows gave place to various kinds of fire-arms, but the British archers continued formidable gentlemen to face. We find that, during the reign of Queen Elizabeth, companies of infantry numbered from 150 to 300 men. Each company had a colour, and were armed in five different ways. A company formed up for attack, or defence, would appear thus:-- [COLOUR] 25 30 40 40 40 40 40 30 35 Arque- Archers. Muskets. Pikes. Halberds. Pikes. Muskets. Archers. Arque- busiers. busiers. It was customary to unite a number of companies into one body called a regiment, which frequently numbered 3000 men, exclusive of officers. Armour was gradually laid aside by the infantry in the 17th century, as it was not proof against the musket-ball, which weighed one-tenth of a pound.
