1809 engagement of the Peninsular War
The Battle of Maguelone was a naval engagement which occurred on 25 October 1809 during the Peninsular War between a French Imperial Navy squadron of three ships of the line and two frigates and a six-ship squadron of the British Royal Navy. In a running battle, the French squadron covered the retreat of a convoy they were escorting and attempted to escape from the British by sailing in shallow waters close to the shore of Villeneuve-lès-Maguelone. After two French ships of the line ran aground, their crews evacuated and scuttled them after removing valuable equipment, including the cannons onboard. The remaining ships of the French squadron then escaped to Toulon. A British cutting out party subsequently attacked the convoy off Roses, Girona on 1 November, destroying most of it and capturing three ships.
Background.
On 21 October 1809, a French Imperial Navy squadron under the command of Counter-Admiral François-André Baudin left Toulon, escorting a convoy bound for Barcelona that was intended to resupply French troops stationed in Spain as part of the Peninsular War. British Vice-Admiral Cuthbert Collingwood, having received word of the French departure from Barcelona, left Cape Sicié with a Royal Navy force of 15 ships of the line and five frigates to ambush the convoy off Cape Saint Sebastian. Two British frigates were also posted off Toulon to observe French naval movements. 
The French squadron detected five British warships to the west of them near Cape Saint Sebastian on 23 October. With a light easterly wind, Baudin ordered the convoy to seek shelter in Roses, Girona, and had his squadron sail into the Mediterranean Sea. By noon, 14 British warships were in sight. In the night, the weather deteriorated and Baudin's squadron had to reduce sail, which was made difficult and longer to do than usual by the squadron's lack of training. On the morning of 24 October, the squadron found itself near the coast, and by 07:30, Baudin ordered his ships to anchor. With 16 metres under keel, he signaled his intention to set sail soon and seek refuge off Sète.
Battle.
On 25 October, the French squadron left their anchorage of Baie des Roses and sailed to the west, close to shore, with light winds from the east. The British resumed their chase, catching up on the French, as the wind was stronger further off at sea. Baudin ordered "Pauline" to run to Sète to warn of the incoming British squadron and have coastal defences manned and ready. At 11:30, the French ships started to touch bottom, and Baudin gave freedom of manoeuver to his captains. "Borée" managed to reach deeped waters, but "Robuste" and "Lion" ran aground.
"Robuste" and "Lion" rested on a bed of rock and hard sand, "Lion" east of "Robuste", both ships out of range of the British. Meanwhile, "Pauline" and "Borée" came in range and exchanged a few shots with HMS "Tigre" and "Leviathan". Captain Senez, of "Borée", planned to anchor off Sète, but Ensign Vallat, captain of the "aviso" "Provençale", which was patrolling the area, offered to pilot "Borée" into the harbour. The manœuver succeeded, putting "Borée" out of reach of the British squadron. "Pauline" mirrored the actions of "Borée" and also entered the port.
With the sea growing heavier, the British stayed off Baudin's ships, but "Robuste" and "Lion" were sustaining increasing damage and leaking water. It soon became obvious that the ships could not be raised, and would have to be abandoned and scuttled. Charles Louis Joseph de Gau de Frégeville, the commander of the local national guard, requisitioned boats and mobilised national guards from Montpellier to assist in rescue operations. In the early morning of the 26th, Frégeville went on "Robuste" to confer with Baudin and offer assistance, and they decided to set a battery on the shore and light fires, as to deter an assault by British boats. They started evacuating the crew and stripping the ships from all useful equipment. In the afternoon, the British ships closed in and launched boats; the French fired on them with four- and six-pounder field guns that Frégeville had had installed aft of "Robuste", and launched their own boats to engage the British party. At 18:30, Baudin signaled that he was about to set his ships on fire. "Robuste" and "Lion" exploded in the night.
On 1 November, British cutting out parties from , , , , , , and , attacked the convoy anchored at Baie des Roses. The transports were protected by the 18-gun fluyt , under Captain Jacques Labretesche, the "avisos" and , and the pink "Normande". Some of the British boats took heavy casualties in the clash. Still, they captured three merchantmen, and set ten ships on fire, including "Lamproie". The "aviso" "Victoire", under Garibou, resisted three boarding attempts before being destroyed.
Aftermath.
"Amélie", having broken her bowsprit, escaped to Marseille and returned to Toulon on 3 November. "Borée" and "Pauline" arrived at Toulon on the 19th.
In January 1813 prize money was awarded to the British vessels that took part in the action for the capture of the ships of war "Grondeur" and "Normande", and of the transports "Dragon" and "Indien". A court declared a joint captor. Head money was also paid for "Grondeur" and "Normande" and for the destruction of "Lamproie" and "Victoire". In 1847 the Admiralty awarded the Naval General Service Medal with clasp "1 Nov. Boat Service 1809" to all surviving claimants from the action.
