 The First Novgorod Chronicle tells that in 1142 a Swedish "prince" and bishop accompanied by a fleet of 60 ships plundered just three Novgorodian merchant vessels somewhere "on the other side of the sea", obviously being after something more important.Almost every year of the 1150s has been suggested as the year that the crusade possibly took place.Most widely supported years have been years 1150, 1155, 1157 and 1158.
