It is obvious, however, that the Swedish-Norwegian attack failed, since Cnut remained master of his realm and was able to make a pilgrimage to Rome in 1027. On his way back to Denmark he dictated a letter, saying that he intended to make peace with the peoples and nations which had tried to deprive him of his kingdom and life but had failed since God deprived them of their power. In the following year Olaf II was driven from Norway and Cnut was hailed as overlord in his stead. Cnut also claimed to be king over part of the Swedes in these years. Coins in the name of Cnut were minted in Svealand at about the same time. All this suggests that the peoples around Lake Mälaren may have ousted Anund Jacob for a while, and hailed Cnut. The possibility of a brief Danish suzerainty in Central Sweden has engendered considerable debate; on one hand Cnut's coins might simply be copied from the Anglo-Danish coinage in a mechanical way, but on the other hand a number of numismatists have argued that the coins are too original in making to be considered copies. At any rate King Anund Jacob was in power again around 1030. Supporting Magnus the Good When expelled by Cnut, Olaf II of Norway went via Sweden to Kievan Rus with his son Magnus. In 1030 he made an attempt to regain his throne. Anund Jacob provided him with a force of 400 skilled men, and allowed him to recruit as many men as possible from his realm. Olaf's plan seems to have been to bypass the Danish fleet typically stationed close to Öresund and try to seize the then Norwegian capital of Nidaros directly by entering through Jämtland. Snorri Sturluson reports that Anund Jacob provided Olaf with pathfinders that guided him through the treacherous terrain of Dalarna to reach the then Norwegian province of Härjedalen. However, Olaf was killed fighting a Norwegian peasant army at the Battle of Stiklestad in 1030. Five years later his son Magnus came over to Sigtuna in Sweden from Rus and met with his stepmother Astrid Olofsdotter, Anund Jacob's sister. According to Snorri's account, supported by a number of contemporary scaldic verses,
