Born into a naval family , Macnamara served in the East Indies during the last years of the American War of Independence , seeing action with Hughes at the Battle of Cuddalore . He received the acting rank of lieutenant during this time , but reverted to midshipman afterwards . He returned to naval service during the Spanish and Russian armaments , and was serving with Lord Hood aboard on the outbreak of the French Revolutionary Wars . He saw action in the Mediterranean and was eventually promoted to his own commands . He achieved success as a daring frigate captain , serving with Nelson and making several hard - fought captures . He finished his service in the Mediterranean with action at the Battle of Cape St Vincent , and later served in the West Indies before the Peace of Amiens . Macnamara found himself in trouble with the law after killing a man in a duel , but summoned a bevy of naval officers to testify in his defence , and was acquitted . He commanded a number of ships of the line in the following years , in the Baltic , North Sea and off of the French coast . He was promoted to rear - admiral in 1814 , but did not receive a seagoing command . He married in 1818 and died in 1826 , having served with prominent naval officers like Hood , Jervis and Nelson in a long and distinguished career . Family and early life . Macnamara was born into a naval family in 1768 in County Clare , and entered the navy in 1782 aboard the 80 - gun . " Gibraltar " went out that year to the East Indies , flying the broad pennant of Commodore Sir Richard Bickerton . On his arrival he was transferred to the 74 - gun , the flagship of the station commander , Sir Edward Hughes . Macnamara saw action at the Battle of Cuddalore on 20 June 1783 against M . de Suffren , in which battle " Superb " sustained losses of 12 men killed and 41 wounded . He was then given an acting rank of lieutenant aboard the 68 - gun and returned to England with her . He then reverted to the rank of midshipman and served aboard the 50 - gun at Jamaica . " Europa " was at the time the flagship of Admiral Alexander Innes . After some years in this position , he received his lieutenant ' s commission on 1 December 1788 and went on to serve during the Spanish armament in 1789 and the Russian armament in 1791 . He was first aboard the 74 - gun under Captain John Gell , later following him to the 100 - gun , flying the flag of Admiral Lord Hood . French Revolutionary Wars . Macnamara continued to serve with Hood aboard " Victory " after the outbreak of war with Revolutionary France in 1793 . He took part in the occupation of Toulon and was promoted by Hood to the rank of master and commander on 22 October 1793 , at about the time of the evacuation of the port . He was appointed acting captain of the 74 - gun , followed by the 32 - gun . Despite these commands an official mistake meant that his commission as post captain was dated 6 October 1795 . " Southampton " was assigned to a squadron commanded by Commodore Horatio Nelson , supporting the Austrian army in Genoa . Command of " Southampton " . Macnamara they spent 15 days in September 1795 blockading a French grain convoy in the port of Genoa . The convoy was protected by two frigates , the " Vestale " and the " Brun " . The French finally came out on the evening of the fifteenth day , and were engaged by " Southampton " , despite the French possessing considerably more firepower . After a sustained engagement " Southampton " forced " Vestale " to strike her colours while the " Brun " escaped with the convoy , leaving " Vestale " to her fate . But as " Southampton " prepared to lower her boats to take possession of the French ship , her fore - mast , which had been damaged during the engagement , went by the board . Taking advantage of this , " Vestale " raised her colours and escaped from the scene . Macnamara had another chance to distinguish himself , when on 9 June 1796 a French corvette was sighted entering Hyères bay , and Vice - Admiral Sir John Jervis , commander of the Mediterranean Fleet , summoned Macnamara to his flagship , HMS " Victory " . He asked Macnamara to bring out the French ship if he could . Recognising the difficulty and risk that would be involved , he did not make it a formal written order , instead instructing Macnamara ' bring out the enemy ' s ship if you can ; I ' ll give you no written order ; but I direct you to take care of the king ' s ship under your command . ' Macnamara promptly took his ship in under the guns of the batteries , and apparently having been mistaken for a French or neutral frigate , closed to within pistol shot of the French ship , and demanded her captain surrender . The captain replied with a broadside , and Macnamara brought " Southampton " alongside and sent his first lieutenant , Charles Lydiard , over in command of the boarders . After subduing fierce resistance Lydiard took possession of the French ship and together he and Macnamara escaped out to sea under heavy fire from the French shore batteries . Macnamara reported his triumph to Jervis The prize , a 24 - gun corvette named " Utile " , was taken into service with the Royal Navy as HMS " Utile " and Lydiard was promoted and given command of her , a commission confirmed on 22 July 1796 . Macnamara ' s later service with Nelson included the capture of Portoferraio , the evacuations of Caprera and Corsica , and expeditions against Piombino and Castiglione . Macnamara had already developed a reputation for intrepidity bordering on recklessness , and he displayed these qualities again in an attack on the 18 - gun Spanish brig " Corso " in a strong gale under enemy shore batteries . The first attempt to capture her failed , with only one man , the coxswain , getting on board . Macnamara tried again , managing to place 30 men aboard the Spanish ship , at which she surrendered . Having done so the weather prevented any further attempt to make contact with the prize . One of Macnamara ' s last acts in support of the Mediterranean Fleet was to take part in the Battle of Cape St Vincent on 14 February 1797 , in which " Southampton " formed part of the centre of the line as a repeating frigate . Captain of " Cerberus " . " Southampton " returned to Britain within a few months of the battle , and Macnamara was appointed to command the 32 - gun , initially on the Irish station . During his time there he captured the 10 - gun French privateer " Echange " , and on 20 October 1799 came across a convoy of Spanish merchantmen escorted by five frigates and two brigs . Despite the enemy ' s numerical superiority Macnamara attacked and captured one of the frigates , but was forced to abandon his prize after the other Spanish frigates came to her defence . He also captured a merchant ship , and having took her men off , burnt her . " Cerberus " sustained minor damage during the engagement , and had only four men wounded . The Admiralty showed their approval of Macnamara ' s actions by promoting his first lieutenant . Macnamara was then sent out to the West Indies , where he cruised off Jamaica and San Domingo until the Peace of Amiens . " Cerberus " was then paid off in February 1803 , and Macnamara went ashore . Duel . While ashore during the peace Macnamara contrived to become embroiled in a duel . While walking his Newfoundland dog in Hyde Park on 6 April 1803 he had an altercation with a Colonel Montgomery , when their dogs began fighting . Harsh words were exchanged , and the two parties fought a duel that evening at Chalk Farm . Both men were wounded , the colonel mortally . Macnamara was arrested on a charge of manslaughter and put on trial at the Old Bailey on 22 April . Macnamara defended himself from the charge on the grounds that he had received an affront and that it was necessary for him to challenge it in order to maintain his position as a naval officer . He summoned many of his naval friends , among whom Viscounts Hood and Nelson , Lord Hotham , Sir Hyde Parker , Sir Thomas Troubridge , Captains Martin , Towry , Lydiard , Moore and Waller ; and General Churchill and Lord Minto , to testify in his defence . They supported his assertion that he was the ' reverse of quarrelsome ' and the jury took ten minutes to acquit him . Napoleonic Wars . Macnamara returned to service with the resumption of the wars with France and took command of the 64 - gun in June 1805 for service in the North Sea . He commanded her for two years on this station before taking command of the 74 - gun . Macnamara served with the Baltic Fleet under Sir Richard Goodwin Keats in the Great Belt in 1808 . During this service he took command of a squadron of gunboat s and attacked a Danish brig and cutter off Nyborg . In a fierce attack , in which seven Danes were killed and thirteen wounded to one British officer killed and two seamen wounded ; both Danish ships were captured . They were found to be the 18 - gun " Fama " and the 12 - gun " Salorman " . Macnamara was then appointed to the 74 - gun in 1809 . This service took him back to the North Sea and then the coast of France . While commanding a small squadron blockading Cherbourg on 24 March 1811 , he chased the French frigate " Amazone " off Barfleur , forcing her crew to abandon and burn her . Flag rank and later life .
