[1] Deloche became assistant secretary of the colonial section of the French Communist Party in October 1936.
[1] A report that Deloche wrote on the situation in Algeria for the French Communist Party was sent to Comintern in Moscow.
Deloche wrote that it was "necessary to purge certain Trotskyite agitators, such as Albert Camus ... who have developed a systematic campaign of calumny against the directors of the French Communist Party and its political line.
This resulted in Belbéoch joining the commissariat of the 12th arrondissement of Paris, in which position he could help members of the Resistance to gain false papers, and could help persecuted Jews.
In the autumn of 1944, Deloche was designated chairman of the special delegation of Joinville-le-Pont, and thus as acting mayor.
In the same year, Deloche was elected General Councillor of the Seine for the canton of Saint-Maur-des-Fossés, of which Joinville was part.
As mayor, Deloche's main achievement was construction of the Joinville-le-Pont stadium on the Avenue des Canadiens.
