Forced, from its creation, to rest because of World War II, the USM organized friendly matches with the teams of El Makarem de Mahdia and the Etoile du Sahel (ESS), based in Sousse, a city which is hard hit by the bombings of 1942. Helping its neighbor, the USM bears the travel expenses of the ESS which amounted to 2,000 francs in 1945 and which the ESS reimbursed in 1954. If the end of the war coincided With a renewed interest and enthusiasm among the Monastirians for football, the USM has more than one hundred players, half of whom play in the senior team and the second half in the junior categories, the following years will be more difficult.
