In the following year, on 29 April 1911, Dubly started in the final of the Challenge International du Nord in Tourcoing, helping his side to a 2–1 win over the English club Cambridge Town.[7] In February 1914, the local press described him as "best Tourquennois forward" during a key match against Olympique Lillois, but despite this, he failed to be called up by the French team because of the Lillois' Paul Chandelier, who was much more "scientific".[1] It was only because of Henri Bard's refusal to be selected (who was demanding money), that on 29 March 1914, the 27-year-old Dubly finally earned his first (and only) international cap for France in a friendly match against Italy in Turin, which ended in a 2–0 loss.[2][3][4] He was only called up For many years, it was widely believed that Jules was the brother of Jean Dubly, a fellow international who was born in the same year, but in Roubaix, which is rather close to Tourcoing.[1]
Later career
Dubly was mobilized during the outbreak of the First World War, but just a month later, in September 1914, he was taken prisoner in Maubeuge, spending four years in a prison camp in Chemnitz, where he was able to play football to kill time.[1] He was repatriated only on 11 December 1918, one month after the Armistice of 11 November 1918.[1]
Despite his advanced age of 33, Dubly once again put on the UST jersey, and in May 1919, he was even selected for Northern France, a regional football scratch team representing the Northern Committee of the Union des Sociétés Françaises de Sports Athlétiques (USFSA).[1] In September of the same year, he was hailed as "the best forward" in a match against Racing de Roubaix (2–2), and his form was such that he was even selected as a substitute for the match against Switzerland in February 1920 in Geneva, when he was approaching 34 years old, which was exceptional at the time.[1] In 1921, he was still a substitute for US Tourcoing, during the semifinal of the Coupe de France against Olympique de Paris, which ended in a 2–3 loss.[1]
Later life
Employed in a textile factory, Dubly was nonetheless president of US Tourquennoise, which had a brief professional adventure in the 1930s before returning to amateurism, and also a municipal councilor of Tourcoing.[1]
Dubly died in Tourcoing on 21 November 1953, at the age of 66.[1]
