First: The commands were various and disunited. That personal system which had arisen five hundred years before, and more, when the old Roman tradition of the Frankish monarchy gradually transformed itself into a series of summonses to lords who should bring their vassals, was still the method by which a French host was tardily and irregularly summoned. For general and lengthy expeditions it was sufficient. For the prosecution of the innumerable local conflicts of the Middle Ages it was actually necessary. Upon occasion at long distances from home, and after long companionship in the field, if there were also present a very leading character among the feudal superiors, and especially if that character were clothed with titular rank, it could achieve something like unity of command. But Philip's army, the last contingents of which were still in act of joining him, enjoyed no such advantages. At least five separate great bodies, four of which were largely subdivided, were loosely aggregated over miles of country, gathering as they went chance reinforcements, and losing by chance defections. Secondly: A certain proportion of regular paid men, including the foreign mercenaries, accompanied the King of France. These were in part with the King himself, in part detached to watch the passages of the river. Thirdly: The King, with a considerable personal force, and with some of his mercenaries as well, was up in the neighbourhood of Saigneville upon the noon and early afternoon of the Thursday. He retraced his steps towards Abbeville, and recrossed the river there himself either upon the Thursday evening, or more probably upon the Friday. Fourthly: Round about Abbeville the bulk of the incongruous force was gathered when the King reached it, and very considerable bodies lay in the suburbs to the north of the town. Finally, we know that on the Saturday morning the King heard Mass and took Communion at the Church of St Stephen (now demolished).
