King Hakon after this battle made a law, that all inhabited land over
the whole country along the sea-coast, and as far back from it as
the salmon swims up in the rivers, should be divided into ship-raths
according to the districts; and it was fixed by law how many ships there
should be from each district, and how great each should be, when the
whole people were called out on service. For this outfit the whole
inhabitants should be bound whenever a foreign army came to the country.
With this came also the order that beacons should be erected upon the
hills, so that every man could see from the one to the other; and it is
told that a war-signal could thus be given in seven days, from the most
southerly beacon to the most northerly Thing-seat in Halogaland
