Charles de Gaulle responded on May 24 by calling for a referendum, and [...] the revolutionaries, led by informal action committees, attacked and burned the Paris Stock Exchange in response. The Gaullist government then held talks with union leaders, who agreed to a package of wage-rises and increases in union rights. The strikers, however, simply refused the plan. With the French state tottering, de Gaulle fled France on May 29 for a French military base in Germany. He later returned and, with the assurance of military support, announced elections [within forty days. [...] Over the next two months, the strikes were broken (or broke up) while the election was won by the Gaullists with an increased majority.
