Moll JEthelwald, who may have been a brother of Eadberht, succeeded, and after a victory over a certain Oswine, who fell in the battle, abdicated and became a monk probably under compulsion in 765.
Centrifugal migration is usually a matter of compulsion; it may be necessitated by natural causes, such as a change of climate leading to the withering of pastures or destruction of agricultural land, to inundation, earthquake, pestilence or to an excess of population over means of support; or to artificial causes, such as the wholesale deportation of a conquered people; or to political or religious persecution.
Service is nominally voluntary, though it appears that a certain amount of compulsion is exercised.
On compulsion he stood in their midst and said: " O God, king of the universe, since these who stand with me are thy people and the besieged are thy priests, I pray thee that thou hearken not to those against these, nor accomplish what these entreat against those."
He warmly advocated both the Munitions bill and the Registration bill, and had no hesitation in taking the further step of compulsory service, asserting, on the first Military Service bill, that the choice was between compulsion and defeat, and on the second bill, that the first had brought in more men than was expected and, therefore, that there was every reason to anticipate the success of the second.
