In 1915 he was foced to land during active service behind Ottoman lines and surived capture. He was interred - along with other Australian and Allied prisoners of war - at Aifion Kara Hisar, in Asia Minor, the former Armenian quarter having been converted into a POW camp.
He would escape from Ottoman custody in Constantinople, making his way through Russia then engulfed in Civil War, eventually arriving in northern Greece and safety, as the First World War came to an end.
In 1928 he published his war memoirs - Guests of the Unspeakable - which recounted the story of his capture, time as a POW and escape.
He also bore witness to the Armenian genocide that was occurring around him in Asia Minor.
