Four white trefoils sprang up wherever she trod." The touch of pure fancy removes its object out of the sphere of passion into one of delight and reverence.

It is strange, as we have said, to pass from the world of actual Welsh history into such a world as this. But side by side with this wayward, fanciful stream of poesy and romance ran a torrent of intenser song. The old spirit of the earlier bards, their joy in battle, their love for freedom, their hatred of the Saxon, broke out in ode after ode, in songs extravagant, monotonous, often prosaic, but fused into poetry by the intense fire of patriotism which glowed within them. The rise of the new poetic feeling indeed marked the appearance of a new energy in the long struggle with the English conqueror.

Of the three Welsh states into which all that remained unconquered of Britain had been broken by the victories of Deorham and Chester, two had long ceased to exist. The country between the Clyde and the Dee had been gradually absorbed by the conquests of Northumbria and the growth of the Scot monarchy. West Wales, between the British Channel and the estuary of the Severn, had yielded to the sword of Ecgberht. But a fiercer resistance prolonged the independence of the great central portion which alone in modern language preserves the name of Wales. In itself the largest and most powerful of the British states, it was aided in its struggle against Mercia by the weakness of its assailant, the youngest and least powerful of the English states, as well as by the internal warfare which distracted the energies of the invaders. But Mercia had no sooner risen to supremacy among the English kingdoms than it took the work of conquest vigorously in hand. Offa tore from Wales the border land between the Severn and the Wye; the raids of his successors carried fire and sword into the heart of the country; and an acknowledgement of the Mercian over-lordship was wrested from the Welsh princes. On the fall of Mercia this passed to the West-Saxon kings.

The Laws of Howel Dda own the payment of a yearly tribute by "the prince of Aberffraw" to "the King of London." The weakness of England during her long struggle with the Danes revived the hopes of British independence. But with the fall of the Danelaw the Welsh princes were again brought to submission, and when in the midst of the Confessor's reign the Welsh seized on a quarrel between the houses of Leofric and Godwine to cross the border and carry their attacks into England itself, the victories of Harold re-asserted the English supremacy. His light-armed troops disembarking on the coast penetrated to the heart of the mountains, and the successors of the Welsh prince Gruffydd, whose head was the trophy of the campaign, swore to observe the old fealty and render the old tribute to the English Crown.

A far more desperate struggle began when the wave of Norman conquest broke on the Welsh frontier. A chain of great earldoms, settled by William along the border-land, at once bridled the old marauding forays. From his county palatine of Chester, Hugh the Wolf harried Flintshire into a desert; Robert of Belesme, in his earldom of Shrewsbury, " slew the Welsh," says a chronicler, " like sheep, conquered them, enslaved them, and flayed them with nails of iron." Backed by these greater baronies a horde of lesser adventurers obtained the royal " licence to make conquest on the Welsh." Monmouth and Abergavenny were seized and guarded by Norman castellans; Bernard of Neufmarche' won the lordship of Brecknock; Roger of Montgomery raised the town and fortress in Powysland which still preserves his name. A great rising of the whole people in the days of the second William at last recovered some of this Norman spoil. The new castle of Montgomery was burned, Brecknock and Cardigan were cleared of the invaders, and the Welsh poured ravaging over the English border. Twice the Red King carried his arms fruitlessly among the mountains, against enemies who took refuge in their fastnesses till famine and hardship had driven his broken host into retreat.

The wiser policy of Henry the First fell back on his father's system of gradual conquest, and a new tide of invasion flowed along the coast, where the land was level and open and accessible from the sea. The attack was aided by internal strife. Robert Fitz-Hamo, the lord of Gloucester, was summoned to his aid by a Welsh chieftain; and the defeat of Rhys ap Tewdor, the last prince under whom Southern Wales was united, produced an anarchy which enabled Robert to land safely on the coast of Glamorgan, to conquer the country round, and to divide it among his soldiers. A force of Flemings and Englishmen followed the Earl of Clare as he landed near Milford Haven, and pushing back the British inhabitants settled a "Little England" in the present Pembrokeshire. A few daring adventurers accompanied the Norman Lord of Kemeys into Cardigan, where land might be had for the winning by any one who would "wage war on the Welsh".

It was at this moment, when the utter subjugation of the British race seemed at hand, that a new outburst of energy rolled back the tide of invasion and changed the fitful resistance of the separate Welsh provinces into a national effort to regain independence. A new poetic fire, as we have seen, sprang into life. Every fight, every hero, had suddenly its verse. The names of the older bards were revived in bold forgeries to animate the national resistance and to prophesy victory. It was in North Wales that the new spirit of patriotism received its strongest inspiration from this burst of song. Again and again Henry the Second was driven to retreat from the impregnable fastnesses where the "Lords of Snowdon," the princes of the house of Gruffydd ap Conan, claimed supremacy over Wales. Once a cry arose that the King was slain, Henry of Essex flung down the royal standard, and the King's desperate efforts could hardly save his army from utter rout. In a later campaign the invaders were met by storms of rain, and forced to abandon their baggage in a headlong flight to Chester. The greatest of the Welsh odes, that known to English readers in Gray's translation as " The Triumph of Owen," is Gwalchmai's song of victory over the repulse of an English fleet from Abermenai. The long reigns of the two Llewelyns, the sons of Jorwerth and of Gruffydd, which all but cover the last century of Welsh independence, seemed destined to realize the hopes of their countrymen.
