Oswald, a prince more nearly allied to the crown, took arms against Adelard; but he being suppressed, and dying soon after, the title of Adelard was not any further disputed; and in the year 741, he was succeeded by his cousin Cudred.

The reign of this prince was distinguished by a great victory, which he obtained by means of Edelhun, his general, over Ethelbald, king of Mercia.

His death made way for Sigebert, his kinsman, who governed so ill, that his people rose in an insurrection, and dethroned him, crowning Cenulph in his stead.

The exiled prince found a refuge with Duke Cumbran, governor of Hampshire; who, that he might add new obligations to Sigebert, gave him many salutary counsels for his future conduct, accompanied with some reprehensions for the past.

But these were so much resented by the ungrateful prince, that he conspired against the life of his protector, and treacherously murdered him.
