Olaf listened in patience to all these things, asking many questions concerning them. At last Cerdic appealed to him and besought him most earnestly to come to repentance and to make himself a faithful follower of Christ, so that he might at the close of his earthly life be worthy to enter into the kingdom of heaven.
Now Olaf Triggvison had until this time lived always in the firm hope that when he died he would be admitted into the shining hall of Valhalla, where he might expect to meet all the great heroes of past times. He believed that Odin would receive him there, and reward him well for all the glorious deeds that he had done. So he was not at all willing to abandon this Norseman's faith in a future life which, as men promised, should be full of warfare by day and of merry carousing by night.
Yet it was evident that Cerdic had not spoken without good effect; for Olaf agreed--as many of the Scandinavians did in these times--that he would at once be christened, on the one condition that, while calling himself a follower of Christ, he should not be expected to abandon either his belief in Odin or his hopes of Valhalla. The holy man of Scilly well knew that this divided faith would not last long, but he was also assured that in the contest the victory would certainly rest with Christ.
Accordingly Olaf was christened, with all his warriors and shipmen. He lay among the Scilly Isles for many days thereafter, and learned the true faith so well that it remained his guiding light throughout the rest of his life, and made him, as shall presently be seen, one of the most zealous Christians of his time.
Now, as the summer days passed by and it drew near to the harvest time, Olaf bethought him of his tryst with King Sweyn Forkbeard, so he raised his anchors and sped out into the open main and round by the forelands, and so north to Ipswich. It was three years since he had first besieged the East Anglian town, and in the interval the folk had returned to their devastated dwellings and built them anew. Olaf now took forcible possession of the town for a second time. He was not yet so entirely a Christian that he had any scruples in attacking Christian folk and turning them out of their homes.
He lay with his ships in the Orwell for three weeks, and at the end of that time King Sweyn and his fleet arrived from the Baltic. Olaf had already gathered about him some fifty-five vessels of war, fully manned and equipped; and with those which Sweyn added to the number, he had now a force of ninety-four ships of all sizes, from small skiffs of ten banks of oars and a crew of a hundred men, up to great dragonships with thirty pairs of oars, two towering masts, and a complete company of about four hundred seamen and warriors. The whole force of ninety-four ships carried with them some thirty thousand men.
This was not to be one of the old plundering raids of a body of adventurers seeking merely to better their fortunes by winning themselves new homes at the point of the sword. It was an expedition greater than any that Brihtnoth had ever met with steel or Ethelred with gold, and its purpose was one of deliberately planned invasion and conquest.
At first when Olaf and Sweyn met and joined their fleets and armies there was a disagreement between them as to which chief was to assume the higher command. Sweyn declared that the leading position was his by the right that he was a king, and should be accorded the more power in all things over Olaf, who (as Sweyn supposed) was lowly born. But Olaf stoutly maintained that as it was he who had proposed the expedition, and as he had the larger number of men and ships, the sole command should be his own, Sweyn taking the second place. In the end it was agreed that this should be so, and that, in the event of their success, they were to divide the kingdom of England between them--Sweyn taking the Northern half, including Northumbria and the upper part of Mercia, and Olaf the Southern half, including East Anglia and the whole of Wessex.
The first point of attack was to be London--a city which, although not yet the capital of the kingdom, was a chief bulwark of the land and daily becoming one of the most important centres of trade in Western Europe. Alfred the Great, who had himself rescued the city from the Danes, had built a strong fortress for her defence, and her citizens had always been regarded as among the most valiant and patriotic in all England. Olaf Triggvison was well aware that if he should succeed in taking London, his conquest of the rest of Ethelred's realm would be a comparatively easy matter. Unfortunately for his plans, he did not foresee the obstacles which were to meet him.
He led his procession of battleships up the Thames. Never before had such a splendid array been seen upon those waters. The early morning sun shone upon the gilded birds and dragons on the tops of the masts. At the prow of each vessel there was reared the tall figure of some strange and terrible animal, formed of carved and gilded wood or of wrought brass, silver, or even amber. Many of the ships had sails made of the finest silk, woven in beautiful designs. The decks were crowded with men whose glittering spears and burnished helmets gave them a very warlike aspect, and struck terror into the hearts of the people who saw them from the river's banks.
