On a hot July day in 1361, 1,300 poorly armed men stood their ground to defend their city of Wisby against the pressure of King Waldemar. Unfortunately, the defenders were slaughtered. It was three days before the besieged city capitulated and the defenders were finally able to come out to bury the dead. Putrifying in the hot sun, pits were dug in the peat bogs and the bodies hurriedly cast in and buried. In the 1920s, Bengt Thordeman and a team of archeologists excavated at the site of the burial and produced a work that has stood the test of time.
