Fate of the Mediterranean
In spring, Admiral Osborne finally received more ships to strengthen the Gibraltar-Mediterranean fleet but it was still less than what he originally wanted, along with instructions to make another attempt at blockading Toulon. Other troubling news Osborne received was reports that the new Spanish King was being less friendly to British interests, and beginning a recruitment of troops, and constructing a few new naval vessels ships in their dockyards. Also that Spain was putting pressure on the new Queen of Portugal to curb their relations with Britain.
Regardless of his worries, Osborne sent out with a strong fleet to blockade Toulon, though when he arrived there was not as many ships in the harbor as he hoped. Admiral Osborne was able to maintain the blockade from March 29th and through all the month of April and part of May, before getting reports that a few of his at sea resupply ships had been sunk or captured by a large French fleet between the French coast and Minorca.
Naval Action of April 25th
French ships under Admiral La Clue sunk and capturef four British frigates. The HMS Jason (44), and HMS Centuar (24) were sunk in action, HMS Unicorn (28) and HMS Blandford (20) were captured along with two British supply ships of less than 20 guns. The damaged HMS Greyhound (24) made it to the British blockade fleet to report the event, while other surviving British supply ships fled back to Gibraltar. Minimal French fleet damaged was incurred.
Clear French Victory.
Battle of Toulon
On May 7th, a few days after British Admiral Henry Osbourne had gotten word of the Naval actions of April 25th, Admiral La Clue arrived with the majority of the French (and unexpectedly) an Austrian Fleet, and bore down on the British blockade fleet. While the two fleets were engaged, several French ships that had been trapped in the harbor by the blockade ventured out to assist.
French Fleet: 18 Ships of the line, 7 Frigates, 12 ships of less than 20 guns (half in harbor)
Foudroyant (80), Ocean (80), Conquerant (74), Temeraine (74), Culloden (74) (ex-british)*, Redoubtable (74), Guerrier (74)*, Hector (74), Centaure (74), Souverain (74), Saint-Espirit (74)*, Modeste (64), Sage (64), Saint Anne (64)*, Valliant (64), St. Albans (60) (ex-british)*, Fier (60), Oriflamme (50), Roebuck (44) (ex-british)*, Ambushcade (40)*, Pleiade (32)*, Chimere (30), Minerve (30), Oiseau (30), Gracieuse (26)
*These ships were trapped in harbor at the time of the blockade, some of which (ex-british and ships in prior battles) were in various states of repair, and had limited participation in the battle.
Austrian Fleet: 1 Ship of the line, 5 frigates, 3 ships of less than 20 guns*
Santa Barbara (70), Austria (40), San Leopoldo (40), Vienna (30), Pegaso (30), Delphino (30)
*(I could find little information on Austria’s Navy during this period so much of this is made up, but I did choose ship names that did exist at various later (or unknown) points in time OTL during the 18th-19th century.)
British Fleet: 13 Ships of the line, 9 frigates, 10 ships of less than 20 guns
St. George (90), Ramillies (90), Monarch (74) (ex-french), Resolution (74), Temple (70), Essex (70), Monmouth (70), Swiftsure (70), Hampton Court (66), Lion (64) (ex-french), Jersey (60), Princess Louisa (58), Guernsey (50), Enterprise (44), Torrington (44), Eltham (40), Diana (32), Thames (32), Actaeon (28), Lizard (28), Greyhound (24) (damaged), Mercury (20)
A fierce exchange of fire lasting most of the day damaged both fleets, and some British ships chased too far to the French coastal defenses took heavy fire. It soon became clear that the battle would be a loss for the British as several ships became crippled or sank. Osborne issued a retreat, and were pursued by the French for several days afterwards all the way to Gibraltar. As before however, the French broke off pursuit as the British neared the defenses of the great rock.
Austrian Losses: 1/3 of their fleet moderately damaged. No ships lost.
French Losses: Half the surviving fleet suffered moderate to heavy damage.
Sunk in Action: Temeraine (74), Fier (60), 2 ships of less than 20 guns.
Condemned after damage assessment: Roebuck (44), Ambushcade (40), 1 ship of less than 20 guns.
British Losses: 2/3rds of the surviving fleet suffered moderately to heavy damage, the remaining suffered light damage. Not a single British ship of the line or frigate returned to Gibraltar unscathed.
Sunk in action: St. George (90), Lion (64), Lizard (28), 1 ship of less than 20 guns.
Condemned after damage assessment: Monarch (74), Eltham (40)
Captured by French: Princess Louisa (58), Diana (32), Greyhound (24)*, 3 Ships of less than 20 guns.
*The Greyhound (24), was later condemned by the French due to the extent of damage.
Decisive French Victory
As a result of this loss of this important battle several things occurred affecting the rest of the war. Admiral Osborne was recalled to London to face an inquiry, and would not return to Gibraltar for the remainder of the war.
Great Britain would not make another attempt to blockade the French Mediterranean coast for the remainder of the war. The Atlantic blockade would be lightened in order to reinforce Gibraltar. This allowed for an increase in much needed French Atlantic trade during 1759-1760, as more goods could slip through the British net.
Britain would pursue a policy of containing the French Fleet inside the Mediterranean Sea. Additional diplomatic efforts would be put upon Portugal to keep them pro-British, especially in light of Spain starting to take a more anti-British stance. The Levant Company was official folded in August of 1759.
The presence and participation of Austrian ships at the Battle of Toulon would finally result in Parliament issuing and delivering a formal declaration of war against Austria on August 1st 1759.
