Born in 1887, Clair Wallace Hayes was an American writer remembered chiefly for his World War I juvenile fiction. Public-domain library records connect him with a long run of Boy Allies novels, including The Boy Allies on the Firing Line, The Boy Allies at Verdun, and The Boy Allies in the Balkan Campaign.
Catalog and bookselling sources also describe him as a journalist, which fits the quick pace and headline-ready drama of his fiction. His stories typically follow resourceful young protagonists through major wartime settings, blending action, military events, and adventure for younger readers.
Hayes also wrote under the pseudonym Robert L. Drake—sometimes styled Ensign Robert L. Drake—especially for entries in the companion Boy Allies with the Navy line. Reliable biographical detail beyond his birth year is hard to confirm from the sources available here, but his books remain widely preserved through projects like Project Gutenberg and other online libraries.
