Second Lieut Leslie Wyndham Mansell, Derbyshire Yeomanry attached to the Durham Light Infantry, was killed in action in France on April 22nd, 1917.

Although his family lived in Bromley, Kent, Leslie had lived in Luton for some time and his father, Mr Harry Milton Mansell, was involved in the cardboard box firm of C. A. Coutts, of the Victor Works, 106 Old Bedford Road, Luton. Leslie was about to enter the firm at London when war broke out.

Leslie Mansell was in his 20th year when he enlisted in the Honourable Artillery Company in September 1914. He obtained his commission the following year and was gazetted to the Derbyshire Yeomanry, before later being attached to the Durham Light Infantry. He went to the front in September 1916.

Following Second Lieut Mansell's death, Colonel Rosher wrote to his family: "On April 21st he had done very fine work leading a successful attack with great gallantry, and on the next day in another attack was killed instantly by a shell."
