"[6] In March 1934 he was director of journal La Révolution nationale and an executive committee member of the Democratic Republican Alliance.

[9] In 1935 he was elected municipal councilor for the Auteuil quarter of Paris, a position he continued to hold until being made president of the council in 1941.

[3] In 1936 Trochu and 29 other councilors proposed building underground highways so the population could be evacuated safely in case of an air attack with chemical weapons.

When the Spanish Civil War broke out in 1936, he used this position to recruit Frenchmen willing to fight for the right-wing forces led by General Francisco Franco.

He and his private secretary, Jacques Pecheron, arranged for these men to travel to Bordeaux to join the Jeanne d'Arc Battalion being assembled by Henri Bonneville de Marsagny.

Thus, during the municipal council meeting of 21 December 1938, he spoke out against "ignoble Jews" such as Bernard Lecache and his friends of the International League against Racism and Anti-Semitism, which, among other infamies, trample on military honor.

"[14] On 4 March 1939 in the Salle Wagram he gave Charles Maurras his sword as an academician, funded by national subscription and designed by Maxime Real del Sarte.

[16] A law of 16 October 1941 gave a new administrative organization to the City of Paris and the Department of the Seine under the traditional name of the Municipal Council, but with appointed rather than elected members.

[17] The PUP members remained in office, but new councilors were selected from the syndicalist workers' movement to replace the communists, an illegal party since 1940, and socialists who had been excluded because they were Jews or Freemasons.
