In 1918, Gault divorced his first wife over what he suspected was an affair with a young officer from his regiment while recovering from his wounds. Marguerite claimed it was a harmless flirtation and many who knew her well agreed. Gault was unsuccessful in his divorce proceedings before the Senate of Canada (the only recourse then open to Quebec residents). Their divorce was finally settled in the much more lenient French courts. Afterwards she was briefly married to Italian aviator Colonel Luigino Falchi.
