17751777 Levant returned to Portsmouth in early 1775, but put to sea again on 22 June amid the early stages of the
American Revolutionary War. In March 1776 she anchored in the Bay of
Algiers where the
Dey, or local ruler, received her warmly and provided the crew with supplies of bread, vegetables, and three live sheep. In November 1776
Levant secured a substantial prize with the capture of another South Carolina vessel,
Argo, carrying rice and indigo worth £37,200.
Argo was to have exchanged her cargo in
Bordeaux for clothing and medicine to supply the American rebellion. Further success followed in early 1777 with the capture of the 18-gun American privateer
General Montgomery.
17781780 Levant continued her Mediterranean patrols in 1778 and was rewarded on 24 March with the recapture of a British merchantman which had been bound for
Newfoundland when seized by an American privateer off Gibraltar. On the same day as this capture,
Levant fell into company with the 28-gun frigate . Her captain, Sir Thomas Rich, advised that he was pursuing , a 22-gun American privateer with three captured merchant ships in tow. On 21 March the privateer had surprised and destroyed

tender before escaping into the night. Rich had given chase for the next three days; Murray now added
Levant to the hunt and the two British frigates set courses to
windward and leeward of the Americans' likely path. Both sailed through the night without sighting their prey. In the morning of 25 March they encountered one of
Revenges prizes, the 16-gun British merchantman
Hope, which promptly surrendered and was returned to Gibraltar. France entered the war against Britain after signing a formal
Treaty with the United States in March 1778. There was a subsequent reorganization of Royal Navy forces in the Mediterranean, with
Levant joining a squadron of four other vessels based in Gibraltar under the overall direction of Admiral
Robert Duff. Of this squadron,
Levant was the second largest, behind only Duff's 60-gun flagship . In July
Levant encountered and captured
Robert, an American merchant vessel that had been bound for Boston with a cargo of salt. In August she took her first French prize of the War a merchantman with a cargo of tobacco and recaptured the British schooner
Lively, which had previously been seized by an American privateer off Scotland's
Western Islands. Two more French prizes followed:
Victorieux seized
en route to Marseilles, and
Duchess of Grumont, which surrendered off Toulon. The captured vessels were sent under guard to Gibraltar. These ongoing victories belied the changing conditions applicable to
Levants hunt for enemy vessels off Gibraltar. American vessels had become scarce, especially since Spain had closed her ports to them in the winter of 1777 in retaliation for privateer attacks on Spanish ships. French trading vessels remained at sea but were occasionally accompanied by naval escorts large enough to prevent their capture by Gibraltar's small Royal Navy squadron.
Levant was
careened on a beach at Gibraltar over Christmas 1778 and then returned to sea, but her next capture was not until 14 March 1779 when in company with Captain Rich's
Enterprise she seized a French vessel,
Thésée. A further victory followed on 1 April when
Levant, still in company with
Enterprise, took
Eclair, a French
xebec carrying wine and
brandy from Marseilles. On 12 April 1779 Spain signed the
Treaty of Aranjuez with France, setting terms for a joint military alliance against Britain. Despite the Treaty Spain delayed the formal declaration of war until June, to give time for better co-ordination of its battle fleet. In the interim
Levant engaged and defeated a Spanish privateer whose crew were caught in the act of boarding a British merchant ship. A brief exchange of cannon fire holed the Spanish vessel below the waterline, sinking her;
Levant rescued the majority of her crew and transported them to prison in Gibraltar. Captain Murray then took
Levant on a cruise to hunt for French or American vessels off Cadiz. While pursuing this task in June 1779 he ran across the Spanish battle fleet, comprising 32 ships of the line and two frigates, heading south towards an unknown destination. Spain was still nominally a neutral power and after a brief exchange of pleasantries the Spanish fleet left
Levant unmolested and continued on its way. Murray immediately set sail for England to report that the Spanish were at sea, pausing off
Land's End on 17 July to capture the French privateer
La Revanche.
Levant finally reached Portsmouth in late July but by this time Murray's news of the Spanish fleet was out of date; Spain had already declared war on Britain and her fleet had reached Gibraltar to commence an
extended siege. ==Final voyages==
