We may presume that the importance of Cookham was maintained for some two centuries after the Conquest, until it was outflanked and the stream of its traffic diverted by the building of the bridge at Maidenhead.

Just as this bridge came later than the Bridge at Henley, so it was inferior to it in structure; it was, as we have seen, of timber, but such as it was, it was the cause of the growth of Maidenhead much more than was the bridge at Henley the cause of the growth of Henley. The first nucleus of municipal government grows up in connection with the Bridge Guild; the Warden and the Bridge Masters remain the head of the embryonic corporation throughout the sixteenth and seventeenth centuries, and even when the town is incorporated (shortly before the close of the seventeenth century), by James II., the maintenance and guardianship of the wooden bridge remained one of the chief occupations of the new corporation.

It was just after the granting of the Charter that the army of William III. marched across this bridge on its way to London, an episode which shows how completely Maidenhead held the monopoly of the Western road. The present stone bridge was not built to replace the old wooden one until the last quarter of the eighteenth century, parallel in this as in everything else to the example of Henley; and this position of inferiority to Henley, and of parallel advance to that town, is further seen in the statistics of population. In 1801, when Henley already boasted nearly 2000 souls, Maidenhead counted almost exactly half that number. The later growth of the place is quite modern.

The antiquity of the crossing of the Thames at Cookham is supported by a certain amount of pre-historic evidence, worth about as much as such evidence ever is, and about as little. Two Neolithic flint knives have been found there, a bronze dagger sheath and spear-head, a bronze sword, and a whole collection or store of other bronze spear-heads. Such as it is, it is a considerable collection for one spot.

Cookham has not only these pre-historic remains; it has also fragments of British pottery found in the relics of pile dwellings near the river, and two Roman vases from the bed of the stream; it has further furnished Anglo-Saxon remains, and, indeed, there are very few points upon the river where so regular a continuity of the historic and the pre-historic is to be discovered as in the neighbourhood of this old ford.

In was in the course of the Middle Ages, and after the Conquest, that new Windsor rose to importance. It is not recognised as a borough before the close of the thirteenth century; it is incorporated in the fifteenth.

Reading certainly increased considerably with the continual stream of wealth that poured from the abbey; it possessed in practice a working corporation before the Dissolution, was famous for its cloth long before, and had become, in the process of years, an important town that rivalled the great monastery which had developed it; indeed it is probable that only the privileges, the conservatism, of the abbey forbade it to be recognised and chartered before the Reformation.

Abingdon also grew (but with less vigour), also had a manufactory of cloth, though of a smaller kind, and was also worthy of incorporation at the end of the Middle Ages.

Staines cannot take its place with these, for in spite of its high strategical value, of its old Roman tradition, of its proximity to London and the rest, Staines was throughout the Middle Ages, and till long after, rather a village than a town. Though a wealthy place it is purely agricultural in the Domesday Survey, and the comparative insignificance of the spot is perhaps explained by the absence of a bridge. That absence is by no means certain. Staines after all was on the great military highway leading from London westward, and it must have been necessary for considerable forces to cross the river here throughout the Dark Ages and the early Middle Ages, as did for instance, at the very close of that period, the barons on their way to Runnymede; and far earlier the army that marched hurriedly from London to intercept the Danes in 1009, when the pagans were coming up the river, and whether by the help of the tide or what not, managed to get ahead of the intercepting force. But if a bridge existed so early as the Conquest, we have no mention of it. The first allusion to a bridge is in the granting of three oaks from Windsor for the repairing of it in 1262. It may have existed long before that date, but it is significant that in the Escheats of Edward III., and as late as the twenty-fourth year of his reign—that is, after the middle of the fourteenth century—it is mentioned that the bridge existed since the reign of Henry III., which would convey the impression that in 1262 the bridge had first needed repairing, being built, perhaps, in the earlier years of the reign and completed, possibly, but a little after the death of King John.

This bridge of Staines was most unfortunate. It broke down again and again. Even an experiment in stone at the end of the last century was a failure, because the foundations did not go deep enough into the bed of the river. An iron absurdity succeeded the stone, and luckily broke down also, until at last, in the thirties of the nineteenth century, the whole thing was rebuilt, 200 yards above the old traditional site.
