In the few hurried months before Hastings the last of the great Anglo-Saxon meetings in the town was summoned. It was held at the end of October, 1065, and was that in which Harold's policy was agreed to. Within twelve months Harold himself was dead, and a victorious invading army was marching upon Wallingford.
In all this record it is clear that Oxford held a continually growing place in the life of England, and especially as a stronghold of whoever might be governing England. What battle was fought there, if any, or how the Normans got it, we do not know, but it is presumed that it suffered in the fighting because the number and value of its houses is given in the subsequent Survey as having fallen very largely indeed.
It is always well, whenever one comes across the Domesday Survey in history, to remember that the whole record is very imperfectly understood. We do not know quite what was being measured: we do not know, for instance, in the case of a town like Oxford, whether all the inhabited houses were counted; or whether only those who by custom gave taxes were counted; nor can we be certain of the meaning of the word vastus, save that it has some connection either with destruction or dilapidation, or lack of occupation, or, possibly, even remission of taxation. But the theory of a sack is not without foundation, for we know that in the case of York (which was certainly sacked by Tostig in 1065 and then again by William in 1068) what is probably a destruction of a similar kind, though a rather greater one, is expressed in similar words.
Whether, however, the number given in the town list of the Conqueror is or is not due to the destruction wrought by the Conquest we must be very careful not to estimate the population of that time upon the basis to-day such a list would afford. The figures of Domesday stand for a much larger population than most historians have hitherto been inclined to grant, as may be shown by considerations to which I shall only allude here, as I shall have to repeat them more fully upon a later page when I speak of urban life upon the Thames. The nomadic element in the life of the early Middle Ages; the smallness of the space allotted for sleeping; the large amount of time spent out of doors; the great proportion of collegiate institutions, not only monastic but military; the life in common which spread as a habit to so many parts of society beyond the monastic; the large families which (from genealogy) we can trust to be as much a character of the early Middle Ages as they, were not the character of the later Middle Ages, the crowd of semi-servile dependants which would be discovered in any large house—all these make us perfectly safe in multiplying by at least ten the number of households counted in the Survey if we would get at the population of those households, and it must be remembered that the houses counted, even in those parts of England which were fairly thoroughly surveyed, can only represent a minimum number, whatever was the method of counting. The lists may in some instances include every single household in a place, though from what we know of the diversity of local custom this is unlikely. In most places it is far more likely that the list covered but some portion that by custom owed a public tax, and this is especially true of the towns.
After Dorchester, which was the first of the fortresses of the Thames, so far as we have any knowledge, and after Oxford, which came next, and appears to have been founded since the beginning of recorded history in these islands, there remain to be considered the other strongholds which held the line of the valley.
It would be easy to multiply these if one were to consider all fortifications whatsoever connected with the general strategic line formed by the Thames, but such a catalogue would exceed the boundaries set to this book. It is proposed to consider only those which were strictly connected with the passage of the stream, and of such there are but three besides Dorchester and Oxford, for that at Cricklade is doubtful, and in any case determines a passage which could be always outflanked upon either side, while the great fortress of the Tower, lying as it does upon the estuarial Thames below bridges, does directly protect a highway.
These three strongholds directly connected with the inland river are Wallingford, Reading and Windsor, and of the three Wallingford and Windsor were more directly military: the last, Reading, appears to have been but an adjunct to a large and civil population; the fourfold quality of Reading in the history of the Thames, as a civil settlement, as a religious centre, as a stronghold, and as one of the very few examples of modern industrial development in the valley, will be considered later. We will take each of the three strongholds in their order down stream.
What determined the importance of Wallingford is not easy to fix nowadays. The explanation more usually given to the great part which this crossing of the Thames played in the early history of Britain is the double one that it was the lowest continuously practicable ford over the river, and that it held the passage of the great road going from London to the west.
Now it is true that any traveller making from London to Bath, or the Mendip Hills, and the lower Severn would, on the whole, find his most direct road to be along the Vale of the White Horse, but the convenience of this line through Wallingford may easily be exaggerated, especially its convenience for men in early times before the valleys were properly drained. Though the ford at Abingdon was more difficult than the ford at Wallingford, yet the line through Abingdon westward along the Farringdon road was certainly shorter than the line through Wantage. Whether the old habit, inherited from pre-historic times, of following the chalk ridge had produced a parallel road just at the foot of that ridge and so had made Wallingford, Wantage, and all the southern edge of the Vale of the White Horse the natural road to the west, or whether it was that the great run of travel ran, when once the Thames had been crossed at Wallingford, slightly south-west towards Bath, it is certain that the Wallingford and Wantage line is the line of travel in early history.
There is no record, and but very little basis for conjecture, as to the origin of the fortifications at Wallingford. Not much is left of them, and though there is some Roman work in the place it is work which has evidently been handled over and over again. It is certainly somewhat late in English history that this "Walled Ford" is heard of—with the tenth century. Its first castle is, of course, Norman, and contemporary with that of Oxford—or rather a year later than that at Oxford, and from the Conquest onward it remains royal. From that time, also, it is perpetually appearing in English history. It was the place of confinement of Edward I. when, as Prince Edward, he was the prisoner of Leicester. It was the attempt to succour that prisoner which led to his removal to Kenilworth, and finally to that escape which permitted him to fight the battle of Evesham. Wallingford passed to Gaveston in Edward the Second's reign, and, remaining continually within the gift of the crown, to the Despenser in the succeeding generation, and finally to Isabella, who declared her policy from within the walls of Wallingford when she returned to the country. It was next held by her favourite, Mortimer, and we afterwards find it, throughout the fourteenth century, a sort of appanage of the heir-apparent, and especially of the Duchy of Cornwall, to which it was attached until the Reformation. It was for a moment under the custody of Chaucer's son: it nursed the childhood of Henry VI., but with the beginning of the next century it had already lost its importance. After half that century had passed the castle was already falling into disrepair; much of the masonry of the town and of the fortress, lying squared and convenient to the river, had been moved down stream for the new buildings at Windsor, and when, nearly a century later again, the Civil War broke out, it was not until after some considerable repair that the place could pretend to stand a siege. It fell to the Parliament, and, before the Restoration, was carefully destroyed, as were throughout England so many foundations of her past by the orders of Oliver Cromwell.
