An important acquisition certainly: yet the very fact that it had still to be made, illustrates the extremely gradual character of the Saxon conquest of Britain. Two hundred years have now elapsed since the accepted date of the landing of Hengest, one hundred and seventy since Cerdic, one of the latest of the invaders, set foot on the shore of Southampton Water, and yet the West Saxons have only just crossed the Mendip Hills; nearly half of Somerset and the whole of Devonshire and Cornwall have yet to be won. The other records of the reign of Cenwalh relate to his battles, generally unsuccessful, with the Mercian kings. His fellow-Christian, young Wulfhere, ravaged what was left of West Saxon territory north of the Thames, as far as Ashdown. While the territory of Wessex had been in some degree growing towards the west, it was, as we have already seen, curtailed towards the east by the loss of the district of the Meonwaras and the Isle of Wight which were handed over by Wulfhere to Sussex. Altogether there was little in the fortunes of the West Saxon dynasty under Cenwalh, or under the obscure rulers who followed him, to betoken that the hegemony would one day be theirs. When towards the end of the century Caedwalla and Ine appear upon the scene, the prospect somewhat brightens, but the victories of the first and the laws of the second must be dealt with in a later chapter. From this brief review of the relations of the various English kingdoms to one another towards the close of the seventh century, it will be abundantly evident how far we yet were from anything like national unity. There does not even seem to be any dawning feeling of fellowship of race. Angle wages with Angle and Saxon with Saxon a long and embittered warfare; and more than once a Mercian or West Saxon king avails himself of British help to win the victory over his kinsfolk. If Anglo-Saxon unity was at length obtained, and we know that it was not till far on in the tenth century that it was even approximately realised, this result was due undoubtedly to two great causes: the influence of the national Christian Church and the necessity of self-defence against the Scandinavian invaders. With the first of these causes alone we have here to deal. It cannot be doubted that zeal for their new-born Christian faith was already in some measure drawing the English kings together. When Oswald of Bernicia stood sponsor for West Saxon Cynegils, when his brother Oswy persuaded East Saxon Sigebert to forsake the follies of idolatry, a moral bond of union was formed, which might be developed into a political relationship. The consciousness of common interest in the _Civitas Dei_ might well become, and eventually did become, a consciousness of fellow-citizenship in one great country.
