It seemed a narrow chance, but it was the only one. Fortune favored the boy viking. Heavy rains had flooded the lands that slope down to the Maelar Lake; in the dead of night the Swedish captives and stout Norse oarsmen were set to work, and before daybreak an open cut had been made in the lowlands beneath Agnefit, or the "Rock of King Agne," where, by the town of Södertelje, the vikings' canal is still shown to travellers; the waters of the lake came rushing through the cut, and an open sea-strait waited young Olaf's fleet.
"Unship the rudder; hoist the sail aloft!" commanded Rane the helmsman "Sound war-horns all! Skoal to the Viking; skoal to the wise young Olaf!"
A strong breeze blew astern; the Norse rowers steered the rudderless ships with their long oars, and with a mighty rush, through the new canal and over all the shallows, out into the great Norrström, or North Stream, as the Baltic Sea was called, the fleet passed in safety while the loud war-horns blew the notes of triumph.
So the boy viking escaped from the trap of his Swedish foes, and, standing by the "grim gaping dragon's head" that crested the prow of his war-ship, he bade the helmsman steer for Gotland Isle, while Sigvat the saga-man sang with the ring of triumph:
"Down the fiord sweep wind and rain;
Our sails and tackle sway and strain;
Wet to the skin
We're sound within.
Our sea-steed through the foam goes prancing,
While shields and spears and helms are glancing.
From fiord to sea,
Our ships ride free,
And down the wind with swelling sail
We scud before the gathering gale."
What a breezy, rollicking old saga it is. Can't you almost catch the spray and sea-swell in its dashing measures, boys?
Now, turn to your atlases again and look for the large island of Gotland off the south-eastern coast of Sweden, in the midst of the Baltic Sea. In the time of Olaf it was a thickly peopled and wealthy district, and the principal town, Wisby, at the northern end, was one of the busiest places in all Europe. To this attractive island the boy viking sailed with all his ships, looking for rich booty, but the Gotlanders met him with fair words and offered him so great a "scatt," or tribute, that he agreed not to molest them, and rested at the island, an unwelcome guest, through all the long winter. Early in the spring he sailed eastward to the Gulf of Riga and spread fear and terror along the coast of Finland. And the old saga tells how the Finlanders "conjured up in the night, by their witchcraft, a dreadful storm and bad weather; but the king ordered all the anchors to be weighed and sail hoisted, and beat off all night to the outside of the land. So the king's luck prevailed more than the Finlanders' witchcraft."
Then away "through the wild sea" to Denmark sailed the young pirate king, and here he met a brother viking, one Thorkell the Tall. The two chiefs struck up a sort of partnership; and coasting southward along the western shores of Denmark, they won a sea-fight in the Ringkiobing Fiord, among the "sand hills of Jutland." And so business continued brisk with this curiously matched pirate firm—a giant and a boy—until, under the cliffs of Kinlimma, in Friesland, hasty word came to the boy viking that the English king, Ethelred "The Unready," was calling for the help of all sturdy fighters to win back his heritage and crown from young King Cnut, or Canute the Dane, whose father had seized the throne of England. Quick to respond to an appeal that promised plenty of hard knocks, and the possibility of unlimited booty, Olaf, the ever ready, hoisted his blue and crimson sails and steered his war-ships over sea to help King Ethelred, the never ready. Up the Thames and straight for London town he rowed.
"Hail to the serpent banner! Hail to Olaf the Brave!" said King Ethelred, as the war-horns sounded a welcome; and on the low shores of the Isle of Dogs, just below the old city, the keels of the Norse war-ships grounded swiftly, and the boy viking and his followers leaped ashore. "Thou dost come in right good time with thy trusty dragon-ships, young King," said King Ethelred; "for the Danish robbers are full well entrenched in London town and in my father Edgar's castle."
And then he told Olaf how, "in the great trading place which is called Southwark," the Danes had raised "a great work and dug large ditches, and within had builded a bulwark of stone, timber and turf, where they had stationed a large army."
