Ansgar who was already in the kingdom of Athlone, advanced to the castle of the barony of Uisneach which was on the border with the kingdom of Ireland.
So he sent a group of vanguard soldiers to safeguard the road through the frozen swamps, because he had hidden enemy troops.
This because it was a barony that was on the border, so it would be quite normal to be able to find more enemies than usual.
The vanguard troops advanced through the swamps until they could find a small guard post where there were only about 5 warriors.
Which were heating up in the fire, the vanguard soldiers communicated by signals and, without wasting time, surrounded the small guard post.
Once it was completely surrounded, they walked slowly while preparing their crossbows. The warriors who were hungry and cold stared in horror as they were surrounded by enemies.
