Weekly. Edited by A.P. Hatton July-Oct 1921.

"Founded in June 1921 by an amalgamation of four veterans' organisations, the Legion campaigned for the welfare of ex-servicemen and women, lobbying for housing, jobs, medical care, equitable pension rights, and seeking to avoid another war. The magazine had reprinted Kipling's poem 'The Return' on 8 July." (CL 7:314n)
