anti-smuggling operations at the mouth of the St. Lawrence River. His success in the role was such that in 1768 Harvey was given the revenue cutter HMS Swift on similar duties in the English Channel, a role he continued in until 1771 when he was placed in reserve on half-pay. In 1773 an opportunity for adventurous service arrived with the offer of a position on Phipps's ship in which Harvey's friend was planning to explore the North Pole. The expedition also included a young Horatio Nelson. Although the journey did not reach the Pole, it did explore the seas north of Svalbard and scientifically discover the polar bear amongst other achievements. American Revolutionary War With a promotion resulting from the expedition enabling further advancement, Harvey commanded the sloop at the Siege of Quebec in the American Revolutionary War of 1776. His knowledge of the St. Lawrence River and Canadian coastline gave him an advantage in this work and as a result he was raised in 1777 to command the frigate on convoy duty. December 1778 saw a transfer to the 32-gun frigate and in the following year Harvey was engaged in the relief of besieged Jersey and later unsuccessful efforts to intercept the raiding squadron of John Paul Jones.

Through 1780 and 1781, Convert served as a fleet scout and was present during the Battle of the Saintes in 1782, although the ship was too small to serve in the battleline. Shortly after the battle, Harvey was detached from the fleet for convoy duties back to England. After a period of unemployment, Harvey was given command of the frigate for service on the North America station in 1786, but was disappointed to discover that his first lieutenant was Prince William Henry and that Harvey was expected to turn over the captaincy to his subordinate as soon as the ship was at sea. Controlling his disappointment, Harvey conducted the affair with "such discretion as secured to him the lasting friendship of His Royal Highness". Within weeks, Harvey had been transferred to and, aboard her, joined Pegasus in peacetime manoeuvres off the North American station until the ship was paid-off in 1789. In 1788, Harvey eldest son, also named Henry, had drowned in a shipboard accident whilst serving
