sworn by mutual oaths and the brother of the kings was returned. The Kings themselves at this time were not at home but had marched with an army toward Westarfolda, an area in the extreme northwest of their kingdom across the northern tip of Britain, whose princes and people refused to submit to them. When they returned after conquering the Britons and received their brother, who had been sent from the emperor, the sons of king Godofrid were assisted by not a few of the Danish nobles who for some time after leaving their homeland had been in exile with the Swedes. Since hosts of their countrymen joined the sons of Godofrid from all over the land of the Danes, they easily drove the kings from the kingdom after a battle". The Chronicle of Moissac also reports: "Afterwards the sons of Godofrid came with their army and expelled Heriold and Reginfrid and also Hemming from their own kingdom; and they fled into secrecy. Thereupon the militia of the imperial lord Charlemagne received from them many presents, and he sent him [Hemming] back to his brothers with regards and support, in order that they should acquire their kingdom again. The Royal Frankish Annals entries of 814 start with the death of Charlemagne. Louis the Pious became sole emperor and turned to diplomatic relations with other European powers. The Royal Annals then mention the continuation of the conflict among the Danes and that Harald Klak sought refuge in the court of Louis. "Heriold and Reginfrid, kings of the Danes, had been defeated and expelled from their kingdom the year before [813] by the sons of Godofrid, against whom they regrouped their forces and again made war. In this conflict Reginfid and the oldest son of Godofrid were killed. When this had come to pass, Heriold despaired of his cause, came to the emperor [Louis], and put himself under his protection. The emperor received him and told him to go to Saxony and to wait for the proper time when he would be able to give him the help which Heriold had requested." Harald's alliance with Louis the Pious Simon Coupland, a modern historian, has noted that Harald was a pagan exile, seeking refuge and military assistance in the court of a Christian ruler. Coupland notes that Louis granting refuge and preparing said military assistance did not mean this was an "innovative step".
