Haussmann himself did not deny the military value of the wider streets. In his memoires, he wrote that his new boulevard Sebastopol resulted in the "gutting of old Paris, of the quarter of riots and barricades." He admitted he sometimes used this argument with the Parliament to justify the high cost of his projects, arguing that they were for national defense and should be paid for, at least partially, by the state. He wrote: "But, as for me, I who was the promoter of these additions made to the original project, I declare that I never thought in the least, in adding them, of their greater or lesser strategic value." The Paris urban historian Patrice de Moncan wrote: "To see the works created by Haussmann and Napoleon III only from the perspective of their strategic value is very reductive. The Emperor was a convinced follower of Saint-Simon. His desire to make Paris, the economic capital of France, a more open, more healthy city, not only for the upper classes but also for the workers, cannot be denied, and should be recognised as the primary motivation."
