How many times was the who national " fyrd " called out between 1046 and 1065 ?
The king could call up the national militia to defend the kingdom , however in the case of hit and run raids , by Vikings , problems with communication and raising supplies meant that the national militia could not be mustered quickly enough as it was only after the raids were underway that a call went out to landowners to gather men for battle , and large regions could be devastated before the newly assembled fyrd arrived .
