But of those tactics the English knew nothing. Their armies were little more than tumultuous levies, in which men marched and fought under local leaders, often divided by local jealousies. The commissariats of the armies seem to have been so worthless, that they had to plunder friends as well as foes as they went along; and with plunder came every sort of excess: as when the northern men marching down to meet Harold Godwinsson, and demand young Edwin as their earl, laid waste, seemingly out of mere brute wantonness, the country round Northampton, which must have been in Edwin’s earldom, or at least in that of his brother Morcar. And even the local leaders were not over-well obeyed. The reckless spirit of personal independence, especially among the Anglo-Danes, prevented anything like discipline, or organized movement of masses, and made every battle degenerate into a confusion of single combats. But Hereward had learned that art of war, which enabled the Norman to crush, piecemeal, with inferior numbers, the vast but straggling levies of the English. His men, mostly outlaws and homeless, kept together by the pressure from without, and free from local jealousies, resembled rather an army of professional soldiers than a country _posse comitatus_. And to the discipline which he instilled into them; to his ability in marching and manoeuvring troops; to his care for their food and for their transport, possibly, also, to his training them in that art of fighting on horseback in which the men of Wessex, if not the Anglo-Danes of the East, are said to have been quite unskilled,--in short, to all that he had learned, as a mercenary, under Robert the Frison, and among the highly civilized warriors of Flanders and Normandy, must be attributed the fact, that he and his little army defied, for years, the utmost efforts of the Normans, appearing and disappearing with such strange swiftness, and conquering against such strange odds, as enshrouded the guerilla captain in an atmosphere of myth and wonder, only to be accounted for, in the mind of Normans as well as English, by the supernatural counsels of his sorceress wife.
