Great Summer Army

The Great Summer Army was a Viking army from Scandinavia led by Guthrum and Bersi that invaded Anglo-Saxon England during the late 9th century.
The army landed in England in 871, joining the faction of Vikings led by the Sons of Ragnar Lothbrok, forming the Great Heathen Army. This allowed the split of the Viking army into two forces, with one led by Halfdan Ragnarsson to combat the Kingdom of Northumbria in the north, while Guthrum led another against the Kingdom of Wessex to the south.Assassin's Creed: Valhalla
