Bishop Heahmund's army is an elite troop consisting of several hundred well-trained men, carrying a typical shield orned by a red cross, prefigurating the Templar knights. They met the Great Heathen Army at the Battle of Yorktown but were pushed back, taking several casualties.

Bishop Heahmund and his elite warriors
It seems that the recruits of the army came from all the Saxon kingdoms, although the army is sworn by pledge to Heahmund and to King Aethelwulf. The two Saxon Earldomen may have provided parts of the forces.
