[William Cloud Hicklin]

Tolkien was almost certainly familiar with Gildas' De Excidio et Conquestu Britanniae, 'On The Ruin and Conquest of Britain', and this is what the 6th-century monk had to say, in part:

After [Magnus Maximus' departure for the continent with the Roman legions], Britain is left deprived of all her soldiery and armed bands, of her cruel governors, and of the flower of her youth, who went with Maximus, but never again returned; and utterly ignorant as she was of the art of war, groaned in amazement for many years under the cruelty of two foreign nations—the Scots from the north-west, and the Picts from the north.

The Britons, impatient at the assaults of the Scots and Picts, their hostilities and dreadful oppressions, send ambassadors to Rome with letters, entreating in piteous terms the assistance of an armed band to protect them, and offering loyal and ready submission to the authority of Rome, if they only would expel their foes. A legion is immediately sent, forgetting their past rebellion, and provided sufficiently with arms. When they had crossed over the sea and landed, they came at once to close conflict with their cruel enemies, and slew great numbers of them. All of them were driven beyond the borders, and the humiliated natives rescued from the bloody slavery which awaited them. By the advice of their protectors, they now built a wall across the island from one sea to the other, which being manned with a proper force, might be a terror to the foes whom it was intended to repel, and a protection to their friends whom it covered. But this wall, being made of turf instead of stone, was of no use to that foolish people, who had no head to guide them.

The Roman legion had no sooner returned home in joy and triumph, than their former foes, like hungry and ravening wolves, rushing with greedy jaws upon the fold which is left without a shepherd, and wafted both by the strength of oarsmen and the blowing wind, break through the boundaries, and spread slaughter on every side, and like mowers cutting down the ripe corn, they cut up, tread under foot, and overrun the whole country.

And now again they send suppliant ambassadors, with their garments rent and their heads covered with ashes, imploring assistance from the Romans, and like timorous chickens, crowding under the protecting wings of their parents, that their wretched country might not altogether be destroyed, and that the Roman name, which now was but an empty sound to fill the ear, might not become a reproach even to distant nations. Upon this, the Romans, moved with compassion, as far as human nature can be, at the relations of such horrors, send forward, like eagles in their flight, their unexpected bands of cavalry by land and mariners by sea, and planting their terrible swords upon the shoulders of their enemies, they mow them down like leaves which fall at the destined period; and as a mountain-torrent swelled with numerous streams, and bursting its banks with roaring noise, with foaming crest and yeasty wave rising to the stars, by whose eddying currents our eyes are as it were dazzled, does with one of its billows overwhelm every obstacle in its way, so did our illustrious defenders vigorously drive our enemies' band beyond the sea, if any could so escape them; for it was beyond those same seas that they transported, year after year, the plunder which they had gained, no one daring to resist them.

The Romans, therefore, left the country, giving notice that they could no longer be harassed by such laborious expeditions, nor suffer the Roman standards, with so large and brave an army, to be worn out by sea and land by fighting against these unwarlike, plundering vagabonds; but that the islanders, inuring themselves to warlike weapons, and bravely fighting, should valiantly protect their country, their property, wives and children, and, what is dearer than these, their liberty and lives; that they should not suffer their hands to be tied behind their backs by a nation which, unless they were enervated by idleness and sloth, was not more powerful than themselves, but that they should arm those hands with buckler, sword, and spear, ready for the field of battle; and, because they thought this also of advantage to the people they were about to leave, they, with the help of the miserable natives, built a wall different from the former, by public and private contributions, and of the same structure as walls generally, extending in a straight line from sea to sea, between some cities, which, from fear of their enemies, had there by chance been built. They then give energetic counsel to the timorous natives, and leave them patterns by which to manufacture arms. Moreover, on the south coast where their vessels lay, as there was some apprehension lest the barbarians might land, they erected towers at stated intervals, commanding a prospect of the sea; and then left the island never to return.

No sooner were they gone, than the Picts and Scots, like worms which in the heat of the mid-day come forth from their holes, hastily land again from their canoes, in which they had been carried beyond the Cichican valley, differing one from another in manners, but inspired with the same avidity for blood, and all more eager to shroud their villainous faces in bushy hair than to cover with decent clothing those parts of their body which required it. Moreover, having heard of the departure of our friends, and their resolution never to return, they seized with greater boldness than before on all the country towards the extreme north as far as the wall. To oppose them there was placed on the heights a garrison equally slow to fight and ill adapted to run away, a useless and panic-struck company, who slumbered away days and nights on their unprofitable watch. Meanwhile the hooked weapons of their enemies were not idle, and our wretched countrymen were dragged from the wall and dashed against the ground. Such premature death, however, painful as it was, saved them from seeing the miserable sufferings of their brothers and children. But why should I say more? They left their cities, abandoned the protection of the wall, and dispersed themselves in flight more desperately than before. The enemy, on the other hand, pursued them with more unrelenting cruelty than before, and butchered our countrymen like sheep, so that their habitations were like those of savage beasts; for they turned their arms upon each other, and for the sake of a little sustenance, imbrued their hands in the blood of their fellow countrymen. Thus foreign calamities were augmented by domestic feuds; so that the whole country was entirely destitute of provisions, save such as could be procured in the chase.

Again, therefore, the wretched remnant, sending to Agitius, a powerful Roman citizen, address him as follow:—"To Agitius, thrice consul: the groans of the Britons." And again a little further, thus:—"The barbarians drive us to the sea; the sea throws us back on the barbarians: thus two modes of death await us, we are either slain or drowned." The Romans, however, could not assist them, and in the meantime the discomfited people, wandering in the woods, began to feel the effects of a severe famine, which compelled many of them without delay to yield themselves up to their cruel persecutors, to obtain subsistence: others of them, however, lying hid in mountains, caves and woods, continually sallied out from thence to renew the war. And then it was, for the first time, that they overthrew their enemies, who had for so many years been living in their country; for their trust was not in man, but in God; according to the maxim of Philo, "We must have divine assistance, when that of man fails." The boldness of the enemy was for a while checked, but not the wickedness of our countrymen; the enemy left our people, but the people did not leave their sins.

For it has always been a custom with our nation, as it is at present, to be impotent in repelling foreign foes, but bold and invincible in raising civil war, and bearing the burdens of their offences: they are impotent, I say, in following the standard of peace and truth, but bold in wickedness and falsehood. The audacious invaders therefore return to their winter quarters, determined before long again to return and plunder. And then, too, the Picts for the first time seated themselves at the extremity of the island, where they afterwards continued, occasionally plundering and wasting the country

Thereafter follows the well-known tale of Vortigern's fatal invitation to the Saxons.

What one takes away from this is that a population -here, the Britons- which is dependent on outside help to come save it will never be free of the depredations of their enemies: they have to learn to stand up for themselves. This, I suspect, was the thinking of the Valar (< Tolkien).

NB: Gildas has been unfairly criticized for getting the sequence of wall-building wrong, but in fact he was right: the "turf wall" was not the Antonine, which Gildas probably had never heard of, but the original erection of the wall under Hadrian, which archaeologists tell us was an earthwork for most of its length. The rebuilding in stone occurred under Severus. Of course, Gildas was completely wrong in dating both erections to the late fourth century!
