The advent of war in September 1939 did not diminish Gibbons's creative energy. In November she began a series of articles, "A Woman's Diary of the War", for "St Martin's Review", the journal of the London church of St Martin-in-the-Fields. The series ran until November 1943, and includes many of Gibbons's private reflections on the conflict. In October 1941 she wrote: "he war has done me good ... I get a dour satisfaction out of managing the rations, salvaging, fire watching, and feeling that I am trying to work for a better world". In July 1940 Webb enlisted in the Middlesex Regiment, and the following year was commissioned into the King's Royal Rifle Corps. He later served overseas, mostly in Cairo.
