As to the second question, the road from Bicester southward runs straight to Dorchester. At Dorchester, as we have seen, there was no ford, though just below it a Roman ferry has been guessed at.

There may have been a country road running down along the left or north bank of the river to the pre-historic crossing place at Goring and Streatley; but if there was, no trace of it remains, save perhaps in the two place names North Stoke and South Stoke.

A barrier has yet another quality in history, and that quality is perhaps the most important of all. In so far as it is an obstacle it is also a means of defence.

All the great rivers of Europe prove this. They are studded with lines of strongholds standing either right upon their banks or close by; and various as is the character of the different great rivers in their physical conformation, few or none have been unable to furnish sites for fortification. For instance, the slow rivers of Northern France, running for the most part through a flat country, were able to afford fortresses for the Gaulish clans in their numerous islands; the origin of Melun and Paris, for instance, was of this kind. The sharp rocks along the Rhone became platforms for castle after castle: Beaucaire, Tarascon, Aries, Avignon, and twenty others all of this sort.

The Thames, curiously enough, forms an exception; it is an exception even in the list of English rivers, most of which can show a certain number of fortifications along their banks.

In the whole course of the great river above London there are but three examples of fortification, or at any rate of fortification directly dependent upon the river. Of these the first, at Lechlade, is conjectural; the second, at Windsor, came quite late in history, and the only one which seems to have been a primeval fortified site was Dorchester.

There were, of course, plenty of towns and castles susceptible of defence. At one time or another every important settlement upon the Thames was capable of resistance: Oxford was walled, Wallingford was a fortress, Abingdon or Reading could be defended. But these were all, so to speak, artificial. The settlement came first, and after the settlement the necessity of guarding it from attack, and it was so guarded, not by natural means, but by human construction. The castle at Oxford, for instance, stood upon a mound of earth raised by human work. The only considerable place in which the river itself suggested defence from the earliest times appears to have been at Dorchester.

The curious importance of Dorchester in the very origins of English history and the still more curious way in which it sinks out of sight for generations, to revive again in the tenth century, is one of the puzzles of the history of the Thames.

It is useless to pursue an archaeological discussion as to the origin of the place, and still more useless to try and determine why, though certainly the most easily defended, it should originally have been the _only_ heavily fortified spot in the whole of the valley. We know that it was Roman: we know that it was a place of pre-historic fortification before the Romans came: we know that a Roman road ran northward towards Bicester from it, and we also know, or at least we can make a very probable guess, that though it was continuously important, and that the interest of early history is continually returning to it, it can never have been large.

Perhaps the best conjecture upon the origin of Dorchester is that the stronghold grew up as an out-lier to the great fort over the river at the top of Sinodun Hill. The exact and regular peninsula between the bend in the Thames and the mouth of the Thames is obviously suited for fortification: the tributary flows just to the east of this peninsula, exactly parallel with the main river beyond, and covers the peninsula not only with a stream on its east flank, but with a marsh at the mouth. One can imagine that the conspicuous heights of the Sinodun Hills were held, from the very beginning of human habitation in this district, as a permanent fortress, into which the neighbouring tribes could retire during war, and one can imagine that when the river was low in summer, and perhaps fordable, the spit of land before it, which formed an exception to the marshes round about, needed to be protected as a sort of bastion beyond the stream. This theory will at least account for the two great ridges of earthwork going from one water to the other and completely cutting off the peninsula, since it is agreed these works are earlier than the Roman invasion. Whatever its origin, the part which Dorchester plays in the early history of England is most remarkable.

The conversion of England was effected by a process of which we know far more than of any other series of national events before the Danish invasions. That process is more exactly recorded, less legendary, and more consecutively told because it was (to all contemporary watchers) the capital event of the time, and to all posterity the one thing that explained men to themselves.

We know also that, not so much the nucleus of the conversion as the secure vantage from which it marched outward, was the triangle of Kent. We can believe that the civilisation of Kent was something quite separate from the rest of the south-eastern portion of England, and that the many customary survivals which are, to this day, native to the county are remaining proofs of its unique character among the petty kingdoms during the mythical period between the withdrawal of the Romans and the arrival of St. Augustine.

The early hold of civilisation upon Kent is explicable. But when the influence of Rome begins to spread again over England you have distances covered which are astounding; there occur sporadic incidents of the highest importance in spots where they would be the least expected. Among the very first of these is the first baptism of a West-Saxon King.

It was certainly at Dorchester that this baptism took place and the choice of the site, little as we know of the village or city, has filled every historian with conjecture. Up to the very landing of St.

Augustine we are still dependent upon what is half legendary and very meagre record. The chief point indeed as regards this part of the country is the tradition of a battle fought against the British at Bedford by the West Saxons and the occupation of "four towns." This success was put down by tradition to the year 571, but everything was still so dark that even this success is a legend.

Within the lifetime of a man you have the baptism of Cynegil, the king of the West Saxons, at Dorchester, and that baptism takes place less than forty years after the complete submission of Kent.

The Chronicle, in mentioning this date, is no longer upon legendary ground: it is dealing with an event which was kept on record by civilised men who understood the art of writing, who could speak Latin, who could bear their records to Rome, and, what is more, the fact and the date are confirmed by the Venerable Bede.

It is imagined by some authorities that the fulness of the story and its apparent accuracy depend upon access to some early ecclesiastical record preserved at Dorchester and now lost. At any rate, Dorchester, whether because it had been, up till then, an unconquered Roman town, or for whatever other reason, becomes at once the ecclesiastical centre and one to which, even when this baptism takes place, the King of Northumbria was at the pains of travelling southward to, to be present as sponsor for the new Christian.

The story has a special historical interest, because it shows how very vague were the boundaries and the occupancies of the little wandering chieftains of this period. It need hardly be pointed out that no regular division into shires can have existed so early, and, as we have already insisted, the Thames itself was not a permanent boundary between any two definable societies, yet those who regard the Anglo-Saxon Chronicle as historical would show one Penda had appeared a few years before as the chief of a group of men with a new name, the Mercians--probably a loose agglomeration of tribes occupying the middle strip of England; a group whose dialect and measures of land are, perhaps, the ancestors of the modern Midland dialect and most of our measures. Cynegil's baptism could not have taken place in territory controlled by Penda, for he was the champion of all the Anti-Christian forces of the time, and though he had just defeated the West Saxons, and (according to a later legend) pushed back their boundary to the line of the Thames, his action, like that of all the little kings of the barbaric age in Britain, can have been no more than a march with a few thousands, a battle, and a retreat. In a word, the true and verifiable story of Cynegil's baptism is one of the many valuable instances which help to prove the unreliability of that part of the early Chronicle which does not deal with ecclesiastical affairs.

The priest who received Cynegil into the Church was one Birinus, an Italian, and perhaps a Milanese; he appears, from his first presence in Dorchester, to have fixed the seat of a bishopric in that village.

His reasons for choosing the spot are as impossible to discover as are the origins of any other of the characteristics of the place. It was, in any case, as were so many of the sees of the Dark Ages, a frontier see--a sort of ecclesiastical fortress, pushed out to the very limits of the occupation of the enemy.

Whether Dorchester continued to be a bishopric from this moment onwards we cannot tell; but no less than three hundred years afterwards--in the tenth century--it appears again, and this time as the centre of the gigantic diocese which stretched throughout the whole of Middle England and right up to the Humber. The Conquest came, the diocese was cut up just afterwards, and the seat of the bishop finally removed from the village to Lincoln, and with the Conquest the importance of Dorchester as a fortified position, an importance which it had held for untold centuries, began to decline in favour of Oxford.

The artificial chain of fortifications up the Thames Valley, which had their origin under William the Conqueror, will call our attention to many other spots besides Oxford as these pages proceed, but it is interesting at this moment to consider Oxford in its early military aspect, when it succeeded Dorchester, and came forward as the chief stronghold of the upper Thames Valley above Wallingford.

The gravel bank north of the ford, by which what is presumed to have been the drovers' road from south to north crossed the river, had supported a very considerable population, and had attained a very considerable civil importance, long before the Conquest. It is difficult to believe that any new, especially that any extensive, centres of population grew up in Anglo-Saxon Britain, upon sites chosen by the barbarians. The Romans had colonised and densely populated every suitable spot. The ships' crews of open pirate vessels had no qualities suitable to the founding of a town; and when there is no direct evidence it is always safer of the two conjectures in English topography to believe that any spot which we find inhabited and flourishing in the Anglo-Saxon period, even at its close, was not a town developed during the Dark Ages but one which the pirates, when they first entered the island, had found already inhabited and flourishing, though sometimes perhaps more British than Roman. But though this is always the more historical way of looking at the probable origin of an English town it must be admitted that there is no direct evidence of any town upon the site of Oxford before the Danish invasions, and the first mention of the place by name is as late as eleven years after Alfred's death, when it is recorded that Edward, his son, "took possession of London and of Oxford and of all lands in obedience thereunto."

This first mention, slight as it is, characterises Oxford as being the town of the upper Thames Valley at the opening of the tenth century, and we have what is usually a good basis for history--that is, ecclesiastical tradition and a monastic charter--to show us that a considerable monastery had existed upon the spot for a century and a half before this first mention in the Chronicle.

There still exists in the modern town, to the west of it, a large artificial mound, one of those which have been discovered here and there up and down England, and which are characteristic of a late Saxon method of fortification. Before the advent of the Normans these mounds were defended by palisades only, and were used as but occasional strongholds. It may be conjectured that this Saxon work at Oxford dates from somewhat the same period as does the first mention of the town in the Chronicle. Twelve years later Alfred's grandson is mentioned as dying at Oxford. It may be presumed that his death would indicate the presence of a royal palace. We hear nothing more of this town during the remainder of the tenth century, but we have a long account in what is probably an accurate record of the rising of the townsmen against the Danes in the beginning of the eleventh. The Scandinavians made their last stand in the church of the monastery, and the townsmen burnt it. Five years later a new host of Danes took and burnt the town; and four years later again, Sweyn, in his terrible conquering march, captured it, after very little resistance, in the same year in which he took the crown of England. The brief episode of Edmund Ironside again brings the town into history: he slept here upon his way to London in the late autumn of 1016, and here, very probably, he was killed. From that moment the fortress (as it now certainly was) enters continually into that last anarchy which was only cured by a second advent of European civilisation and the success of its armies at Hastings.

The great national council of 1018, which may be called the settlement of Canute, was held at Oxford, and in 1036 another national council, of even greater importance, which was held to decide upon the succession of Canute's heirs, was again held at Oxford, and it was at Oxford that, four years later, the first Harold died.

Meanwhile, in the near neighbourhood of the city, at Islip, Queen Emma had, half a lifetime earlier, borne a son, who, after the death of all these Danes, remained the legitimate heir to the English throne. Islip was, most probably, not royal, but a private manor of the Queen's, which descended to the Confessor, and it is interesting to note in pa.s.sing that it was his gift of this land and of its church to Westminster Abbey which originated the present connection between the two--a connection which has now, therefore, behind it nearly nine hundred years of continuity.

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 s.p.a.ce allotted for sleeping; the large amount of time spent out of doors; the great proportion of collegiate inst.i.tutions, 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 pa.s.sage 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 pa.s.sage 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 pa.s.sage 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 pa.s.sed 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 pa.s.sed 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.

It has often been remarked with surprise that cities and strongholds once densely inhabited and heavily built can disappear and leave no material trace to posterity. That they do so disappear should give pause to those historians who are perpetually using the negative argument, and pretending that the lack of material evidence is sufficient to disturb a strong and early tradition. Those who have watched the process by which abandoned buildings become a quarry will easily understand how all traces of habitation disappear.

Three-quarters of what was once Orford, much of what once was Worsted, has gone, and up and down the country-sides to-day one could witness, even in our strictly disciplined civilisation, the removal, by purchase or theft, of abandoned material.

The whole of Wallingford has suffered this fate--the mound, presumably artificial, upon which the first keep stood, and which was, probably, a palisade mound of Anglo-Saxon times, remains, but there is upon it no remaining masonry.

Next down stream of the points with a strategic importance in English history comes Reading. But the strategic importance of Reading was not produced by the town's possessing a site of national moment: it was produced only by local topography. Reading was never (to use a modern term) a "nodal point" in the communications of England.

It may be generally laid down that mere strength of position is noted and greedily seized in barbaric times alone. For mere strength of position is a mere refuge. A strong position (I do not speak, of course, of tactical and temporary, but of permanent, positions), chosen only because it is strong, will save you during a critical short period from the attack of a fierce, unthoughtful, and easily wearied enemy--such as are all barbarians; but it cannot _of itself_ fall into a general scheme of defence, nor, _simply because it is strong_, intercept the advance of an adversary or support a line of opposition and resistance. Position is always of _advantage_ to a fortress, and, in all but highly civilised times, a _necessity_--as we shall see when we come to discuss Windsor--but it is not sufficient. A fortress, when society is organised, and when the feud of one small tribe or family against another is not to be feared, derives its princ.i.p.al value from a command of established communications, and established aggregations of power--especially of economic power. Towns alone can feed and house armies; by roads and railways alone can armies proceed.

There are, indeed, examples of a chain of positions so striking that, from their strength alone, a strategic line imposes itself; but these are very rare. Another, and much commoner, exception to the rule I have stated is the growth of what was once a barbaric stronghold, chosen merely for its position, into a larger centre of population, through which communications necessarily lead, and in which stores and other opportunities for armies can be provided. Such places often preserve a continuity of strategic importance, from civilised, through barbaric, to civilised times again. Laon is an excellent instance of this, and so is Constantine another, and so is Luxembourg a third--indeed they are numerous.

But, in spite of--or, rather, as is proved by--these exceptions the fortresses of an organised people are found at the conjunction of their communications, or at places (such as straits or pa.s.ses) which have the monopoly of communication, or they are identical with great aggregations of population and opportunity, or at least they are situated in spots from which such aggregations can be commanded.

Position is always of value, but only as an adjunct.

Now Reading, save, perhaps, in barbaric times, when the Thames was the main highway of Southern England, occupied no such vantage until the nineteenth century. To-day, with its large population, its provision of steam and electrical power, and above all, its command of the main junction between the southern and middle railways, Reading would again prove of primary strategic importance if we still considered warfare with our equals as a possibility. But during all previous centuries, since the Dark Ages, Reading was potentially, as it is still actually, civilian; and, indeed, it is as the typical great town of the Thames Valley that it will be treated later in these pages.

The long and narrow peninsula between the Kennet and the Thames was an ideal place for defence. It needed but a trench from the one marsh to the other to secure the stronghold. But though this was evident to every fighter, though it is as such a stronghold that Reading is mentioned first in history, yet the advantage was never permanently held. Armies hold Reading, fall back on the town, fight near it, and raid it: but it is never a great fortress in the intervals of wars, because, while Oxford commanded the Drovers' Road, Wallingford the western road, and Windsor (as we shall see in a moment) London itself, Reading neither held a line of supply nor an acc.u.mulation of supply, and was, therefore, civilian, though it was nearly as easy to hold as Windsor, as easy as Dorchester, its parallel, easier than Oxford, and far easier than Wallingford, which had, indeed, no natural defences whatsoever.

Proceeding with the stream, there is no further stronghold till we come to Windsor.

Even to-day, and in an England that has lost hold of her past more than has any rival nation, Windsor seems to the pa.s.ser-by to possess a meaning. That hill of stones, sharp though most of its modern outlines are, set upon another hill for a pedestal, gives, even to a modern patriot, a hint of history; and when it is seen from up-stream, showing its only n.o.ble part, where the Middle Ages still linger, it has an aspect almost approaching majesty.

The creator of Windsor was the Conqueror. The artificial mound on which the Round Tower stands may or may not be pre-historic. The slopes of the hill were inhabited, like nearly all our English sites, by the Romans, and by the savages before and after the Romans; but the welter of the Saxon dark ages did not use this abrupt elevation for a stronghold. What military reasoning led William of Falaise to discern it at once and there to build his keep?

In order to answer that question let us consider what other points in the valley were at his disposal.
