In time for the 1915–16 season, it had become clear that the war, initially anticipated by all sides to conclude quickly, would last longer than expected. Regardless, Borussia was able to assemble a functional team for the season (reinforced regularly by players on vacation from frontline duty), and played games against Union Krefeld, Viktoria Rheydt, Konstantia Kaldenkirchen, VfB Krefeld, FC Mönchengladbach and Eintracht Mönchengladbach. After a shaky start including a 1–4 friendly game loss to Borussia Düsseldorf, Borussia found its footing in the league, and briefly rivalled Krefeld for the first place in January 1916. Ultimately, Borussia finished second in the league. By mid-1916, Borussia was forced to cease regular play due to the lack of regularly available players. By 4 November 1916, even the provisional club leadership had to cease operations, as too many of its members were called up for military service.
