The 1913–14 season saw a club record attendance of 10,736 for an FA Cup second round match against Preston North End on 31 January 1914. However, the following season they finished bottom of the league and had to apply for re-election. This was curtailed when the start of World War I meant the Football League closed down. Glossop were then re-formed toward the end of the war by Oswald Partington, but failed to be re-elected back into the Football League. Glossop then joined the Lancashire Combination, playing just one season, 1919–20. Northern Nomads ground-shared with Glossop for several years during this time. The club then dropped out of the Lancashire Combination and into the Manchester League. In the 1920s and 1930s they won the Gilcryst Cup three times and were crowned Manchester League champions in 1927–28. They won the Gilcryst Cup for a fourth time in 1947–48.
