[2] During the First World War, he served in the infantry under Colonel Driant in Verdun and a street was named after him in Le Cateau-Cambrésis where he is considered a local hero.

[6] In his book "This is the Tour de France", Michel Duino wrote:[7] "On each arrival, Deloffre performed somersaults for the amazed onlookers.

Deloffre used to thank "his" audience, by singing "Le P'tit Quinquin" when he did not feel like being the acrobat, wearing a top hat.

He also competed in the most prestigious classic races of his time:[8] Deloffre married twice in Caudry, firstly on 12 August 1911 to Joséphine Maria Delcourte and secondly on 24 January 1924 to Anaïs Sophie Deschanvres.

After his sporting retirement, he continued to attend regional races, and it was while riding his bicycle from the 'Criterium International de Cambrai' on 13 October 1963, that he was run over by a car leaving Caudry.
