Not long after the failed Danish raid in Kent, Alfred dispatched his fleet to East Anglia. The purpose of this expedition is debated, but Asser claims that it was for the sake of plunder. After travelling up the River Stour, the fleet was met by Danish vessels that numbered 13 or 16 (sources vary on the number), and a battle ensued. The Anglo-Saxon fleet emerged victorious, and as Huntingdon accounts, "laden with spoils". The victorious fleet was surprised when attempting to leave the River Stour and was attacked by a Danish force at the mouth of the river. The Danish fleet defeated Alfred's fleet, which may have been weakened in the previous engagement.
