The Battle of Pulo Aura was a minor naval engagement of the Napoleonic Wars, fought on 14 February 1804, in which a large convoy of Honourable East India Company (HEIC) East Indiamen, well-armed merchant ships, intimidated, drove off and chased away a powerful French naval squadron. Although the French force was much stronger than the British convoy, Commodore Nathaniel Dance's aggressive tactics persuaded Contre-Admiral Charles-Alexandre Durand Linois to retire after only a brief exchange of shot. Dance then chased the French warships until his convoy was out of danger, whereupon he resumed his passage toward British India. Linois later claimed that the unescorted British merchant fleet was defended by eight ships of the line, a claim criticised by contemporary officers and later historians.
The Battle of Groix was a large naval engagement which took place near the island of Groix off the Biscay coast of Brittany on 23 June 1795 during the French Revolutionary Wars. The battle was fought between elements of the British Channel Fleet and the French Atlantic Fleet, which were cruising in the region on separate missions. The British fleet, commanded by Admiral Lord Bridport, was covering an invasion convoy carrying a French Royalist army to invade Quiberon, while the French under Vice-admiral Villaret de Joyeuse had sailed a week earlier to rescue a French convoy from attack by a British squadron. The French fleet had driven off the British squadron in a battle on 17 June known as Cornwallis's Retreat, and were attempting to return to their base at Brest when Bridport's force of 14 ships of the line appeared on 22 June.
Charles-Alexandre Léon Durand, Comte de Linois was a French admiral who served in the French Navy during the reign of Napoleon Bonaparte. He commanded the combined Franco-Spanish fleet during the Algeciras Campaign in 1801, winning the First Battle of Algeciras before losing the Second Battle of Algeciras. He then led an unsuccessful campaign against British trade in the Indian Ocean and South China Sea in 1803, being defeated by a harmless fleet of the East India Company during the Battle of Pulo Aura and ending his cruise and sea-going career being bested in battle by John Warren in the action of 13 March 1806. Following the Bourbon restoration, Linois was appointed Governor of Guadeloupe. He supported Napoleon during the Hundred Days and so, on his return to France, he was forced to resign and was court martialled. Although acquitted, he was placed in retirement and never served again.
HMS Swiftsure was a 74-gun third rate ship of the line of the British Royal Navy. She spent most of her career serving with the British, except for a brief period when she was captured by the French during the Napoleonic Wars in the action of 24 June 1801. She fought in several of the most famous engagements of the French Revolutionary and Napoleonic Wars, fighting for the British at the Battle of the Nile, and the French at the Battle of Trafalgar.
The Sémillante was a 32-gun frigate of the French Navy, lead ship of her class. She was involved in a number of multi-vessel actions against the Royal Navy, particularly in the Indian Ocean. She captured a number of East Indiamen before she became so damaged that the French disarmed her and turned her into a merchant vessel. The British captured her and broke her up in 1809.
Jean-Jacques Rousseau was a Téméraire class 74-gun ship of the line of the French Navy, active during the French Directory, French Consulate and First French Empire. Renamed Marengo in 1802, she took part in Linois' operations in the Indian Ocean before her capture by the Royal Navy.
The Atlantic campaign of 1806 was one of the most important and complex naval campaigns of the post-Trafalgar Napoleonic Wars. Seeking to take advantage of the withdrawal of British forces from the Atlantic in the aftermath of the Battle of Trafalgar, Emperor Napoleon ordered two battle squadrons to sea from the fleet stationed at Brest, during December 1805. Escaping deep into the Atlantic, these squadrons succeeded in disrupting British convoys, evading pursuit by British battle squadrons and reinforcing the French garrison at Santo Domingo. The period of French success was brief: on 6 February 1806 one of the squadrons, under Vice-Admiral Corentin Urbain Leissègues, was intercepted by a British squadron at the Battle of San Domingo and destroyed, losing all five of its ships of the line.
Linois's expedition to the Indian Ocean was a commerce raiding operation launched by the French Navy during the Napoleonic Wars. Contre-Admiral Charles-Alexandre Durand Linois was ordered to the Indian Ocean in his flagship Marengo in March 1803 accompanied by a squadron of three frigates, shortly before the end of the Peace of Amiens. When war between Britain and France broke out in September 1803, Marengo was at Pondicherry with the frigates, but escaped a British squadron sent to intercept it and reached Isle de France. The large distances between naval bases in the Indian Ocean and the limited resources available to the British commanders in the region made it difficult to concentrate sufficient forces to combat a squadron of this size, and Linois was subsequently able to sustain his campaign for three years. From Isle de France, Linois and his frigates began a series of attacks on British commerce across the Eastern Indian Ocean, specifically targeting the large convoys of East Indiamen that were vital to the maintenance of trade within the British Empire and to the British economy. Although he had a number of successes against individual merchant ships and the small British trading post of Bencoolen, the first military test of Linois squadron came at the Battle of Pulo Aura on 15 February 1804. Linois attacked the undefended British China Fleet, consisting of 16 valuable East Indiamen and 14 other vessels, but failed to press his military superiority and withdrew without capturing a single ship.
The Battle of Vizagapatam was a minor naval engagement fought in the approaches to Vizagapatam harbour in the Coastal Andhra region of British India on the Bay of Bengal on 15 September 1804 during the Napoleonic Wars. A French squadron under Contre-Admiral Charles-Alexandre Léon Durand Linois in the ship of the line Marengo attacked the British Royal Navy fourth rate ship HMS Centurion and two East Indiaman merchant ships anchored in the harbour roads. Linois was engaged in an extended raiding campaign, which had already involved operations in the South China Sea, in the Mozambique Channel, off Ceylon and along the Indian coast of the Bay of Bengal. The French squadron had fought one notable engagement, at the Battle of Pulo Aura on 15 February 1804, in which Linois had attacked the Honourable East India Company's (HEIC) China Fleet, a large convoy of well-armed merchant ships carrying cargo worth £8 million. Linois failed to press the attack and withdrew with the convoy at his mercy, invoking the anger of Napoleon when the news reached France.
The action of 13 March 1806 was a naval engagement of the Napoleonic Wars, fought when a British and a French squadron met unexpectedly in the mid-Atlantic. Neither force was aware of the presence of the other prior to the encounter and were participating in separate campaigns. The British squadron consisted of seven ships of the line accompanied by associated frigates, led by Rear-Admiral Sir John Borlase Warren, were tasked with hunting down and destroying the French squadron of Contre-Admiral Jean-Baptiste Willaumez, which had departed Brest for raiding operations in the South Atlantic in December 1805, at the start of the Atlantic campaign of 1806. The French force consisted of one ship of the line and one frigate, all that remained of Contre-Admiral Charles-Alexandre Durand Linois' squadron that had sailed for the Indian Ocean in March 1803 during the Peace of Amiens. Linois raided British shipping lanes and harbours across the region, achieving limited success against undefended merchant ships but repeatedly withdrawing in the face of determined opposition, most notably at the Battle of Pulo Aura in February 1804. With his stores almost exhausted and the French ports east of the Cape of Good Hope that could have offered him replenishment eliminated, Linois decided to return to France in January 1806, and by March was inadvertently sailing across the cruising ground of Warren's squadron.
Sir James Lind KCB was an officer of the Royal Navy who served during the American War of Independence and the French Revolutionary and Napoleonic Wars. The son of James Lind, a distinguished naval physician, Lind also embarked on a career at sea, but served in a more front line role. After serving on a number of different ships he finally received his own command in 1800, but his first chance to show his ability came only in 1803 when in command of HMS Sheerness. Here he captured a French privateer after his imitation of a merchant ship encouraged the privateer to actually attack his heavily armed frigate. He then revealed the true nature of his ship and the hapless privateer had no choice but to swiftly surrender. Promoted to command the 50-gun HMS Centurion Lind had another opportunity to distinguish himself, when the convoy under his protection was attacked in the harbour of Vizagapatnam by a heavily armed French squadron under Rear-Admiral Charles-Alexandre Durand Linois. Despite being on shore at the time Lind hurried back to take command and supervise operations to resist the French, who though were able to capture one of the merchants, decided not to risk pressing the attack on the Centurion and withdrew. The survival of the Centurion in the face of overwhelming forces was hailed as a great achievement back home in Britain, with Lind being knighted for his efforts.
The Atlantic campaign of 1806 was a complicated series of manoeuvres and counter-manoeuvres conducted by squadrons of the French Navy and the British Royal Navy across the Atlantic Ocean during the spring and summer of 1806, as part of the Napoleonic Wars. The campaign followed directly from the Trafalgar campaign of the year before, in which the French Mediterranean fleet had crossed the Atlantic, returned to Europe and joined with the Spanish fleet. On 21 October 1805, this combined force was destroyed by a British fleet under Lord Nelson at the Battle of Trafalgar, although the campaign did not end until the Battle of Cape Ortegal on 4 November 1805. Believing that the French Navy would not be capable of organised resistance at sea during the winter, the First Lord of the Admiralty Lord Barham withdrew the British blockade squadrons to harbour. Barham had miscalculated – the French Atlantic fleet, based at Brest, had not been involved in the Trafalgar campaign and was therefore at full strength. Taking advantage of the reduction in the British forces off the port, Napoleon ordered two heavy squadrons to sea, under instructions to raid British trade routes while avoiding contact with equivalent Royal Navy forces.
Allemand's expedition of 1805, often referred to as the Escadre invisible in French sources, was an important French naval expedition during the Napoleonic Wars, which formed a major diversion to the ongoing Trafalgar Campaign in the Atlantic Ocean. With the French Mediterranean Fleet at sea, Emperor Napoleon I hoped to unite it with the French Atlantic Fleet and together form a force powerful enough to temporarily displace the British Royal Navy Channel Fleet for long enough to allow an invasion force to cross the English Channel and land in Britain. In support of this plan, the French squadron based at Rochefort put to sea in July 1805, initially with the intention that they would join the Atlantic Fleet from Brest. When this fleet failed to put to sea, the Rochefort squadron, under Contre-Admiral Zacharie Allemand, went on an extended raiding cruise across the Atlantic, both to intercept British trade left lightly defended by the concentration of British forces in European waters and with the intention of eventually combining with the French Mediterranean Fleet then blockaded in Spanish harbours.
The Algeciras campaign, or Battles of Algeciras, was a brief naval campaign fought between a combined French and Spanish Navy force and a British Royal Navy force during 4–13 July 1801. A French squadron, seeking to join the Spanish fleet and a number of French ships of the line at the Spanish Atlantic base of Cadiz, sailed from Toulon on 13 June under Contre-amiral Charles Linois. Rounding the British naval base of Gibraltar on the southern coast of Spain on 4 July, Linois learned that a British squadron under Rear-Admiral Sir James Saumarez was on station off Cadiz. Seeking to avoid battle with Saumarez's much larger force, Linois anchored in the Spanish port of Algeciras, close to Gibraltar. Saumarez discovered Linois there on 6 July and attacked at 08:30, his ships hampered by light winds and Linois's strong defensive position.
The action of 7 April 1800 was a minor naval engagement fought between a British squadron blockading the Spanish naval base of Cádiz and a convoy of 13 Spanish merchant vessels escorted by three frigates, bound for the Spanish colonies in the Americas. The blockade squadron consisted of the ships of the line HMS Leviathan and HMS Swiftsure and the frigate HMS Emerald, commanded by Rear-Admiral John Thomas Duckworth on Leviathan. The Spanish convoy sailed from Cádiz on 3 April 1800 and encountered Duckworth's squadron two days later. The Spanish attempted to escape; Emerald succeeded in capturing one ship early on 6 April. The British captured a brig the following morning and the British squadron divided in pursuit of the remainder.
The Algeciras campaign was an attempt by a French naval squadron from Toulon under Contre-Admiral Charles Linois to join a French and Spanish fleet at Cadiz during June and July 1801 during the French Revolutionary Wars prior to a planned operation against either Egypt or Portugal. To reach Cadiz, the French squadron had to pass the British naval base at Gibraltar, which housed the squadron tasked with blockading Cadiz. The British squadron was commanded by Rear-Admiral Sir James Saumarez. After a successful voyage between Toulon and Gibraltar, in which a number of British vessels were captured, the squadron anchored at Algeciras, a fortified port city within sight of Gibraltar across Gibraltar Bay. On 6 July 1801, Saumarez attacked the anchored squadron, in the First Battle of Algeciras. Although severe damage was inflicted on all three French ships of the line, none could be successfully captured and the British were forced to withdraw without HMS Hannibal, which had grounded and was subsequently seized by the French.
The First Battle of Algeciras was a naval battle fought on 6 July 1801 between a squadron of British Royal Navy ships of the line and a smaller French Navy squadron at anchor in the fortified Spanish port of Algeciras in the Strait of Gibraltar. The British outnumbered their opponents, but the French position was protected by Spanish gun batteries and the complicated shoals that obscured the entrance to Algeciras Bay. The French squadron, under Contre-Amiral Charles Linois, had stopped at Algeciras en route to the major Spanish naval base at Cadiz, where they were to form a combined French and Spanish fleet for operations against Britain and its allies in the French Revolutionary Wars. The British, under Rear-Admiral Sir James Saumarez, sought to eliminate the French squadron before it could reach Cadiz and form a force powerful enough to overwhelm Saumarez and launch attacks against British forces in the Mediterranean Sea.
César-Joseph de Bourayne, later Baron Bourayne, was a French naval officer, famous for his battles against British ships in the Indian Ocean and South China Sea. He was appointed Rear-admiral in 1814, having been made a Baron in 1811.
The Second Battle of Algeciras was a naval battle fought on the night of 12 July 1801 between a squadron of British Royal Navy ships of the line and a larger squadron of ships from the Spanish Navy and French Navy in the Gut of Gibraltar.
Martin's cruise of 1794 was the only significant French naval operation of the year in the Mediterranean Sea. In 1793 France had gone to war with Great Britain and a wide coalition of European enemies in the French Revolutionary Wars. Early in the conflict the British had seized the French Mediterranean Fleet and their home port of Toulon, the town enduring a four month siege by French Republican forces in which the fleet was badly damaged. With the town and fleet back in French hands, the French set about effecting repairs as the British attacked the island of Corsica.
