"The basis of the heerban system was the duty of every fighting man to answer directly the call of the king to arms. The freeman, not only of the Franks, but of all the subject peoples, owed military service to the king alone. This duty is insisted upon in the laws of Charlemagne with constant repetition. The summons (heerban) was issued at the spring meeting, and sent out by the counts or missi. The soldier was obliged to present himself at the given time, fully armed and equipped with all provision for the campaign, except fire, water, and fodder for the horses." _E.
