Oasis was a literary anthology published in Cairo during World War II. It was edited by Denis Saunders, David Burk, and Victor Selwyn. The introduction was written by General Henry Maitland Wilson, who was at this time Commander-in-Chief of the Middle East.
Oasis was published in the 1940s.
World War II spanned from 1939 through 1945 so there is a chance that it could have been published during WWII and published in 1939.
