On the night of April 9, 1388, the Austrian army, while plundering villages and farms, was taken by surprise by the Glarners, who emerged from the snow and fog, leading to a brief but decisive battle. The disorganized Austrians broke and fled, but many drowned in the river when the bridge over the Maag or Weeser Linth collapsed. This event marked a turning point in the history of Glarus, securing its independence from Habsburg rule.
