When the king wanted to raise an army, he summoned his major baron tenants-in-chief, who commanded their own armed dependent vassals, and he directed the sheriffs to command the minor tenants-in-chief and supply them with equipment. A baron could assemble an army in a day, but might use it to resist any perceived misgovernment by a king. Armed conflict did not interfere much with daily life because the national wealth was still composed mostly of flocks and herds and simple buildings. Machinery, furniture, and the stock of shops were still sparse. Life would be back to normal within a week. Henry wanted to check this power of the barons. So he took over or demolished their adulterine castles and restored the fyrd, which was a military draft of every freeman to serve in defense of the realm. At the King's call, barons were to appear in mail suit and helmet with sword and horse, knights and freeholders with 213s.[16 marks] of rent or chattels in coat of mail with shield and lance, freeholders of 133s.[10 marks] with lance and hauberk [coat of armor] and iron headpiece, burgesses and poorer freemen with lance and headpiece and wambais, and such as millers with pike and leather shirt. The spiritual and other baronies paid a commutation for personal service, called "scutage", at the rate of 27s. per knight's fee. Barons and knights paid according to their knight's fee a scutage ranging from 10s. to 27s. As of 1181, the military obligations of villeins were defined. The master of a household was responsible for every villein in his household. Others had to form groups of ten and swear obedience to the chief of the group. The sheriff was responsible for maintaining lists of men liable for military service and procuring supplies. This national militia could be used to maintain the peace. The sheriff could call upon the military array of the county as a "posse comitatus" to take a band of thieves into custody or to quell disorder. For foreign wars, Henry decided to use a mercenary army and a mercenary fleet. However, the nobility who were on the borders of the realm had to maintain their private armies for frequent border clashes. The other nobility now tended towards tournaments with mock foot battles between two sides. Although subject to knightly rules, serious injury and death often resulted. For this reason, the church opposed them, but unsuccessfully.
