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