Înălțarea Domnului
Unbeknownst to the king, the allies gathered a considerable army and accosted Eric near Uppsala at Östra Aros when he attended Mass on the Feast of the Ascension in May 1160. The king, being informed of the approach of the enemy, heard mass to the end, then armed himself and the few men at hand, and went out to meet Magnus' troops. He was pulled off his horse onto the ground by the swarming rebels, who taunted and stabbed him, then beheaded him.
