Following the war, he was promoted to lieutenant in October 1920,^[1] before matriculating to the University of Cambridge where he studied at Corpus Christi College, Cambridge in 1921,^[2] Described by Wisden as "a good club batsman",^[3] Gornall made his debut in first-class cricket for the Royal Navy against the British Army cricket team at Lord's in 1921. He remained enlisted in the Royal Navy whilst at Cambridge, allowing him to play in the same fixture in 1923. Gornall appeared for Hampshire in the 1923 County Championship at Portsmouth, before making a final first-class appearance for the Royal Navy against the Army at Lord's in 1924.^[4] In four first-class matches, Gornall scored 149 runs at an average of 18.62, with a highest score of 33.^[5]

Gornall served in the Second World War, being appointed executive officer aboard HMS Shropshire a month prior to the start of the war.^[1] He was appointed Shropshire's commanding officer in March 1941, before being transferred to the shore establishment HMS Kestrel as its commanding officer the following month. Whilst commanding Kestrel, Gornall was promoted to captain in December 1941.^[7] His appointment at Kestrel lasted until October 1943, after which he briefly undertook duties aboard HMS Victory and the shore establishment HMS President. At the beginning of 1941, he was placed in command of the Leander-class light cruiser HMS Orion in the Mediterranean Sea, taking part in the Operation Shingle landings which were a prelude to the wider Battle of Anzio.
