The highest recorded attendance at the club's home ground, Priestfield Road, was 8,000 for the game against Swindon Town in October.

Due to the escalation of the war and public opposition to sporting events continuing as normal, professional football in England closed down at the end of the season and Gillingham would not play another game for more than four years.

[4] Discussions had taken place for several years over whether the two leagues should be amalgamated, or alternatively whether they should remain separate but operate a system of promotion and relegation between the two competitions.

[9][10] The decision was not universally supported, however: while "Sportsman" of the Surrey Mirror wrote that "the provision of healthful recreation and innocent pleasure should be encouraged at this particular stage",[11] the Hull Daily Mail printed a lengthy letter from a correspondent who wrote that it was "jarring and nauseating" to hear of teams preparing for the new Football League season while British soldiers were engaged in conflict.

[1][19][20] The team wore the red and blue kit which had replaced the club's original black and white colours two years earlier.

[24] After the interval, West Ham's goalkeeper made a number of saves but was beaten by a penalty kick from Tom Leslie, after which Gillingham scored twice more to complete a 4–0 win.

[28] On 10 October, Gillingham played the previous season's Southern League champions, Swindon Town,[29] at Priestfield Road.

[23] Glen and Pinkney, who had both missed the previous game due to influenza, returned for the match at home to Queens Park Rangers on 24 October, but neither scored a goal and Gillingham lost 1–0.

[23] After six consecutive defeats, Gillingham began December by coming from two goals down to secure a 2–2 draw at home to Northampton Town.

[38] A week later, they lost 4–0 away to Watford; Don Weightman made his debut at half-back and would play in every game for the remainder of the season.

[23] Glen asked the club's board of directors for permission to miss the Christmas Day game to get married, but his request was refused.

[41] On the night of 28 December, large parts of the south of England were lashed by heavy gales;[42] the new grandstand at Priestfield Road, which had still not been completed, was severely damaged.

[46] Having last won a match on 10 October, Gillingham beat Portsmouth 3–1 at Priestfield Road on 6 February to secure their first victory for more than four months.

[49] Glen was in the team for the first time in six weeks for the game away to Queens Park Rangers on 27 February but failed to score; Gillingham lost the match 3–0.

[50] On 20 March, Gillingham played at home to Croydon Common, who had inflicted their worst defeat of the season on them four months earlier.

[51] The Sporting Life stated that Gillingham deserved to win and were only prevented from doing so by "an extraordinarily smart display of goalkeeping on the part of the Croydon Common custodian".

[52] Having only won four times in the league between September and March, Gillingham began the month of April with two victories on consecutive days.

[57] They were defeated again five days later away to Northampton Town; Gillingham lost 4–0 after being forced to play with ten men for more than an hour after Glen was injured.

[23] There were three players who were in the line-up for only one match, including the goalkeeper F. Hall, whose sole appearance represented the entirety of his Gillingham career.

[23] FW = Forward, HB = Half-back, GK = Goalkeeper, FB = Full-back Owing to the escalation of the war and growing public sentiment that continuing sporting events as normal was not appropriate, all major football competitions in England, including the Southern League, closed down in 1915 and did not resume for four years.

[9][65] Temporary regional leagues, featuring amateur players only, took place in the intervening years, but Gillingham did not take part.
