Herbert Howard Snowden Fowler entered the Royal Naval Air Service on 7 December 1916. Serving with 12 Naval Squadron for less than a month, he was reassigned to 8 Naval Squadron (later 208 Squadron) on 18 August 1917. Flying the Sopwith Camel, Fowler scored six victories in 1918. That summer, he was discharged from the Royal Air Force when it was determined that he was almost completely deaf.
