Cardiff City are invited to take part in a local wartime competion league designed to cut down on travel as much as possible, and to maintain morale. The standard of football is not high, and when most of the players begin to be called away for enlisting in the armed forces, it becomes difficult to raise a side at times. As most other clubs are experiencing the same problems, the games become little more than uncompetitive friendlies, failing to attract much support so interest and attendances dwindle.
