Froissart used a contemporary document proceeding from the pen of one “John the Fair,” a canon of Liége. Of the lesser authorities some are contemporary: notably Baker of Swynford, and Villani, who died shortly after the battle.
But the whole bulk of material at our disposal is pitifully small, and the greater part of what the reader will have set before him in what follows is the result of an expansion and criticism of the few details which writers of the period have bequeathed to us.
When the documentary evidence, contemporary, or as nearly contemporary as possible, has been tabulated, the historian of a medieval battle next proceeds to consider what may be called the “limiting circumstances” within which the action developed, and these have much more than a negative value. As he proceeds to examine and to compare them, they illuminate many a doubtful point and expand many an obscure allusion.
For instance, in the case of Crécy, we carefully consider the contours, upon the modern map, of a terrain which no considerable building operations or mining has disfigured. We mark the ascertainable point at which the Somme was crossed, and calculate the minimum time in which a host of the least size to which we can limit Edward’s force could have marched from that to the various points mentioned in the approach to the battle-field. We ascertain the distance from the scene of action to the forest boundary. We argue from the original royal possession and subsequent conservation of that forest its permanent limits. We can even establish with some accuracy the direction of the wind, knowing how the armies marched, how the sun stood relative to the advancing force, and their impression of the storm that broke upon them. We calculate, within certain limits of error, the distance necessary for deployment. We argue from the known character of the armour and weapons employed certain details of the attack and defence. We mark what were certainly the ancient roads, and we measure the permanent obstacles afforded by the physical nature of the field.
I give these few points as examples only. They are multiplied indefinitely as one’s study proceeds, and in the result a fairly accurate description of so famous, though so ill attested, an action as this of Crécy can be reconstituted.
With all this there remains a large margin which cannot be generally set down as certain, and which even in matters essential must be written tentatively, with such phrases as “it would seem,” or “probably” to excuse it. But history is consoled by the reflection that all these gaps may be filled by further research or further discovery, and that each new effort of scholarship bridges one and then another.
As to the critical power by which each individual writer will decide between conflicting statements, or apparently irreconcilable conditions, this must be left to his own power of discrimination and to the reader’s estimate of his ability to weigh evidence. He is in duty bound—as I have attempted to do very briefly in certain notes—to give the grounds of his decision, and, having done so, he admits his reader to be a judge over himself: with this warning, however, that historical judgment is based upon a vast accumulation of detail acquired in many fields besides those particularly under consideration, and that a competent historian generally claims an authority in his decisions superior to that reposing upon no more than a mere view of limited contemporary materials.

THE POLITICAL CIRCUMSTANCES
The Battle of Crécy was the first important decisive action of what is called “The Hundred Years’ War.” This war figures in many history books as a continued struggle between two organised nations, “England” and “France.” To present it in its true historical character it must be stated in far different terms.
The Hundred Years’ War consisted in two groups of fighting widely distant in time and only connected by the fact that from first to last a Plantagenet king of England claimed the Crown of France against a Valois cousin. Of these two groups of fighting the first was conducted by Edward III., and covers about twenty years of his reign. It was magnificently successful in the field, and gave to the English story the names of Crécy and of Poitiers. So far as the main ostensible purpose of that first fighting was concerned, it was unsuccessful, for it did not result in placing Edward III. upon the French throne.
