On 23 May the next objective of the army was the butte Montmartre, where the uprising had begun. The National Guard had built and manned a circle of barricades and makeshift forts around the base of the butte. The garrison of one barricade, at Chaussee Clignancourt, was defended in part by a battalion of about thirty women, including Louise Michel, the celebrated "Red Virgin of Montmartre", who had already participated in many battles outside the city. She was seized by regular soldiers and thrown into the trench in front of the barricade and left for dead. She escaped and soon afterwards surrendered to the army, to prevent the arrest of her mother. The battalions of the National Guard were no match for the army; by midday on the 23rd the regular soldiers were at the top of Montmartre, and the tricolor flag was raised over the Solferino tower. The soldiers captured 42 guardsmen and several women, took them to the same house on Rue Rosier where generals Clement-Thomas and Lecomte had been executed, and shot them. On the Rue Royale, soldiers seized the formidable barricade around the Madeleine church; 300 prisoners captured with their weapons were shot there, the largest of the mass executions of the rebels.
