War-king

All the inhabitants, excepting the Druids, were trained early to war, and every clan or family fought in a separate band, under the King of its particular nation, and a War King elected as chief general.

Turner thinks that the Bret-walda [...] was a war-king, elected by the other Anglo-Saxon kings and their nobility, as their leader in the time of war.

[T]he fire-dragon had rased the coastal region and reduced forts and earthworks to dust and ashes, so the war-king planned and plotted his revenge.
