Napoleon III also made one last attempt to persuade Italy to be his ally against Prussia. Italian King Victor Emmanuel was personally favorable to a better relationship with France, remembering the role that Napoleon III had played in achieving Italian unification, but Italian public opinion was largely hostile to France; on 3 November 1867, French and Papal soldiers had fired upon the Italian patriots of Garibaldi, when he tried to capture Rome. Napoleon presented a proposed treaty of alliance on 4 June 1869, the anniversary of the joint French-Italian victory at Magenta. The Italians responded by demanding that France withdraw its troops who were protecting the Pope in Rome. Given the opinion of fervent French Catholics, this was a condition Napoleon III could not accept.
