On the eve of World War I in season 1913–14, the club were again crowned champions and Cup winners. This team, including new stars Patsy Gallacher, Jimmy McColl and Andy McAtee plus survivors from the earlier successful squad such as Alec McNair and 'Sunny Jim' Young would win a further three titles, and set a sequence of 62 league games unbeaten (65 including the minor Glasgow Cup and Glasgow Merchants Charity Cup) which would not be surpassed for a century. McMenemy, now in his mid-30s, was one of the Celtic players who worked in reserved occupations during the conflict – in his case manufacturing munitions – so was not called to frontline action and able to continue to playing football whenever possible (in summer 1918 he was due to be called up, with one brother having been killed and another wounded on the battlefield, but fell ill with influenza and did not leave Scotland before the armistice in November of that year). A teammate, Peter Johnstone, was one of those did perish on the Western Front.
