This was Huddersfield's fifth appearance of what would be seven appearances in eight consecutive finals between 1909 and 1919 (which included four successive victories and six in total.) It was also the second of the four consecutive wins.
Background
Britain had declared war on Germany on 4 August 1914 after they had attacked Luxemburg, Belgium and France. A month later the season proper started against this backdrop. The Yorkshire Cup competition started in October and it was to be the last until the end of the war. Tensions had been building across Britain and the rest of Europe for some time, but, despite this, the 1914–1915 season was played to its conclusion, albeit in some cases a little half-heartedly as evidenced in the lower attendances at matches and with several teams absent and many players already enlisted in the Armed Forces. In the middle of 1915 competitive sporting competition was finally suspended. This season there were no junior/amateur clubs taking part, no new entrants and no "leavers" and so the total of entries remained the same at thirteen. This in turn resulted in three byes in the first round.
