Europe

• Spring , King Lambert II travels to Rome with his mother, Queen Ageltrude and brother Guy IV, Lombard duke of Spoleto, to meet Pope Stephen VI to receive reconfirmation of his imperial title. Guy is murdered on the Tiber by agents of Alberic I, a Frankish nobleman with political interests. He seizes Spoleto (possibly at the instigation of King Berengar I) and sets himself up as duke.

Britain

• English warships (nine vessels from Alfred's new fleet) intercept six Viking longships in the mouth of an unknown estuary on the south coast (possibly at Poole Harbour) in Dorset. The Danes are blockaded, and three ships attempt to break through the English lines. Lashing the Viking boats to their own, the English crew board the enemy's vessels and kill everyone on board. Some ships manage to escape, two of the other three boats are driven against the Sussex coast. The shipwrecked sailors are brought before King Alfred the Great at Winchester and hanged. Just one Viking ship returns to East Anglia.
