By the time of the Siege of Paris, the family name of Lilibone was ruined, which Gerswinda blamed on the Norse invaders. In order to drive them back, Gerswinda was at Evresin, where she sought to rally the Frankish women to take up arms and "be the hand of God's judgement against the heathens". She met jarlskona Eivor Varinsdottir of the Raven Clan, who wandered near during one of these recruitments. Gerswinda, along with her allies, attacked Eivor but were ultimately defeated. Reflecting after the battle, Eivor remarked that had Gerswinda's rallying worked, she might have been bested.
