Howard wrote two complete Cormac Fitzgeoffrey stories and left one unfinished before his death. The character is also mentioned in the story The Sowers of the Thunder, set fifty years later and published in 1932.
"Hawks of Outremer"
First published in Oriental Stories (Spring 1931) after being accepted by that magazine in October 1930. "Outremer" (literally, "Oversea") was how the Crusader states were often called.
"The Blood of Belshazzar"
First published in Oriental Stories (Fall 1931) after being accepted by that magazine in December 1930.
Howard left this story as an incomplete synopsis. It was later completed by Richard L. Tierney and first published in 1979 in the Donald M. Grant hardback collection Hawks of Outremer.
