That Fall saw more anti-war actions. The school year started with a large demonstration against the University of Wisconsin in Madison, Wisconsin on October 17 for letting Dow recruiters on campus. Peaceful at first, the demonstrations turned to a sit-in that was violently broken up by the Madison police and riot squad, causing many injuries and arrests. A rally and a student strike then closed the university for several days. Demonstrations against the draft led by members of the Resistance, the War Resisters League, and SDS added fuel to the fire of resistance. After regular civil rights tactics of peaceful pickets, the Oakland California Stop the Draft Week ended in mass hit and run fights with the police. The huge (100,000 people) October 21 March on the Pentagon saw hundreds arrested and hurt. Night-time raids on draft offices began to spread.
