The
Battle of Jengland (also called
Jengland-Beslé,
Beslé, or
Grand Fougeray) took place on 22 August 851, between the Frankish army of
Charles the Bald and the Breton army of
Erispoe,
Duke of Brittany. The Bretons were victorious, leading to the signing of the Treaty of Angers in September 851 which secured Breton independence.
