The Danish troops moved towards Visby.
The first day of the invasion, two minor skirmishes were fought on marshy ground between yeomen farmers and the army.
The next day from 800-1,000 farmers were killed after massing for battle at Mästerby near Fjäle mire.

On 27 July, a Gutnish yeomen army fought the Danes just outside the city walls and was severely beaten, with an estimated death toll of about 1,800 yeomen and peasants; the Danish casualties remain unknown.
Only a couple of items that can be linked with Danish soldiers have been found, including a purse and ornamented armor belonging to a member of the Roorda Family from Friesland.
Casualties can be compared with those that the French suffered at the Battle of Poitiers in 1356 and would be considered high by medieval standards.
