Charles Stanley Phillips, 1911 Encyclopædia Britannica, Volume 8… (1911)
“ In the warfare which ensued Edmund fought at the severest disadvantage, for his armies dispersed after every engagement, whatever its issue. Canute at once fiercely besieged London, but the citizens successfully resisted all attacks. Edmund meanwhile marched through Wessex and received its submission. At Pen in Somersetshire he engaged the Danes and defeated them. Canute now raised the siege of London and soon afterwards encountered Edmund at Sherston in Wiltshire. The battle was indecisive, but Canute marched back to London and left Edmund in possession of Wessex. ”
