There is even more than this. If we follow the present embankment across the estuary towards the southern bank, we find ourselves checked before reaching that bank by the now canalised and artificial straight ditch of the Somme. There is no bridge, but on the further side leading across the remaining 700 yards to the southern bank, a village road exactly continues the direction, and this road, older than the reclamation of the valley, is the last converging point clinching the argument. It cannot be doubted that the road leading from Saigneville northward across the flat to the canal, and continued beyond the canal by the embankment, is the line of the old Blanchetaque.[12] Though the French army had been pursuing Edward during his march upon the left bank of the Somme, the possibility of his getting across the estuary had not been neglected, and a force had been detached to watch the right bank at the point where the only passage across the stream, Blanchetaque, touched that right bank. Here one of Philip's nobles, Godemard de Fay, was waiting with a considerable force to oppose the passage. The exact size of this force is not easy to determine, for it is variously stated, even by contemporary authorities, but we are fairly safe if we reckon it at more than 2000 and less than 4000 men, some hundreds of whom were mounted knights. In other words, it counted in "capital units" from one-sixth to one-eighth of Edward's army, and, counting all fighting men against all fighting men, perhaps much the same proportion. There was sharp fighting, but it was defeated, principally through the action of the Archers. In Godemard's command was a very considerable body of Genoese cross-bowmen. As we shall see when we come to the Battle of Crécy itself, this arm was gravely inferior in rapidity of fire, and possibly in range, to the English long-bow. The latter weapon could deliver three to the cross-bow's one, and to this, coupled with the discipline of the English column, the success must be ascribed. Grave as was the balance of numbers against the French side, equal armament and equal discipline should have enabled it to prevail. The holding of a _tête de pont_ with a smaller number properly deployed should always be possible against a larger column compelled to debouch from a narrow line, especially a line of such difficulty as a ford across a broad stream.
