10 May marked the "Night of Barricades", where students used cars, wood, and cobblestones to barricade the streets of the Latin Quarter. Brutal street fighting ensued between students and riot police, most notably on Rue Gay-Lussac. Early the next morning, as the fighting disbanded, Daniel Cohn-Bendit sent out a radio broadcast calling for a general strike. On Monday, 13 May, more than one million workers went on strike and the students declared that the Sorbonne was "open to the public". Negotiations ended, and students returned to their campuses after a false report that the government had agreed to reopen them, only to discover police still occupying the schools.
