Jacques Hodin joined the CDLR in Reims in October 1942. Dr. Quentin was in charge then, but Henri Bertin took over when he was arrested in June 1943. Hodin was brought into the Possum organisation, through his uncle, Auguste Miel, who was the proprieter of the Taverne de l'Opera in rue de Thillois, Reims.

Hodin, through his contacts in the Resistance, was able to locate airmen, throughout the region, and pass them on to Possum. It is not known how many airmen were retrieved through his efforts and there are no names.

With the arrest of Edgard Potier and others at the end of December 1943, Jacques Hodin went into hiding. He stayed with Dr. Beaumont in Warloy-Baillon (near Amiens) until ~20th January 1944, then with Pierre Guibert, head of police, in Parthenay (~350 kms SW of Paris) until 10th February 1944. Returning to home territory, he stayed with a religious official in Binson (~25 kms SW of Reims) until 2nd May 1944, when he was again forced to flee by a visit of the Gestapo to the house. He took refuge in a barn for three weeks before being taken in by the Moussé family of Cuisles (~5 kms N of Binson) on 20th May 1944. However, on 21st June 1944 Eugène Moussé and his son, Edmond, were arrested at their home. Hodin was hidden in a room and evaded capture. From then until the arrival of the Americans on ~25th August 1944, he worked with the local resistance group in Vandières.

His father, Georges Hodin, was arrested on 4th January 1944 and released in Compiègne, on the arrival of the Americans. Auguste Miel, his uncle, was arrested on 9th June 1944 and deported to Dachau, where he died.
