Camocke was made a commander of the "Lion", a 60-gun ship, and fought with her at the Battle of Beachy Head (1690) and at the Battle of Barfleur (1692). He was later wounded while setting fire to a three-deck French ship at La Hogue and was promoted to first lieutenant of the "Loyal Merchant" soon after (1692–93). The "Loyal Merchant" was part of the fleet that sailed to the Mediterranean with Sir George Rooke.
