Battle of Ilevollene

A raid in Bergen was done shortly after when they heard that Magnus Erlingsson had traveled to Viken for the summer in order to be able to keep possession of the purchase in Oslofjord until the autumn.

After offering leases in Western and Southern Norway from the east of Lindesnes to Møre og Romsdal in the north, Magnus Erlingsson went with a powerful army to the Trondheimsfjord and stopped first at Byneset at Nidaros with the fleet.

The assault at Byneset and Sverre Sigurdsson's mobilization of Leidang men in Trøndelag must have prevented Magnus from continuing towards the city.

Sverre started negotiations with Magnus Erlingsson to buy time to prepare and strengthen the defenses.

With a strong army of landlords and townsmen, an attack on the city could not take place without great difficulty.
