The first took place on Sunday, September 3, at around 8 a.m., when resistance fighters attacked a group of German soldiers on their way to Havré. But the Germans remained combative and the resistance fighters were dispersed. Four of them, who were leading the way, were killed: Gustave De Wilde, José Hennebert, René Joly and Armand Virlet. Their names appear on the monument dedicated to them in the rue de Saint-Symphorien.
