John Dunn was a professional footballer at Luton Town FC when he enlisted in the Footballers' Battalion of the Middlesex Regiment at Kingsway, London on 16th December 1914 with his Luton team mates Wileman, Simms, Frith, Roe and Wilson.

In doing so he was following the example set by his team mates Roberts and Lindley who had signed up the day before. Lindley and Dunn shared lodgings at a house called Ruthaven in Shaftesbury Road, Luton. Dunn continued to be available to play for Luton in the 1914-15 season whilst undergoing military training.

 Robert Frith was a professional footballer at Luton Town FC when he enlisted in the Footballer's Battalion of the Middlesex Regiment in London on 16th December 1914 with his Luton team mates Wileman, Roe, Simms, Dunn and Wilson.

Although he was a married man with two children, the 22 year old half-back decided to follow the example of two other Luton players, Roberts and Lindley, who had signed up the day before. Frith was part of the 1913-14 promotion-winning Luton team and continued to play for Luton in the 1914-15 season whilst in training with his battalion.
