[2] In the 1913 Wimbledon Championships, he won with Agnes Tuckey the first mixed doubles final at Wimbledon in an unusual fashion - one of their opponents Ethel Thomson Larcombe was struck in the eye by her partner's miss-hit smash and unable to continue the match.

The incident occurred when the second set was 5–3 for Crisp and Tuckey, the first having been won by the opposing pair of James Cecil Parke and Mrs Larcombe.

During the First World War, he received a commission in The Duke of Wellington's (West Riding) Regiment.

[3] In April 1915 while attached to the Royal Warwickshire Regiment, he was wounded at Hill 60 near Ypres and his right leg was amputated.

[4] However, with a prosthesis, he returned to Wimbledon to play in the 1919 Championships with Mrs Perrett, losing in the second round after a bye in the first.
