Lord Byron

George Gordon Byron, 6th Baron Byron FRS (22 January 1788 – 19 April 1824) was an English romantic poet and peer. He was one of the leading figures of the Romantic movement, and has been regarded as among the greatest of English poets. Among his best-known works are the lengthy narratives Don Juan and Childe Harold's Pilgrimage; many of his shorter lyrics in Hebrew Melodies also became popular.

Lord Byron was educated at Trinity College, Cambridge, later travelling extensively across Europe to places such as Italy, where he lived for seven years in Venice, Ravenna, and Pisa after he was forced to flee England due to lynching threats. During his stay in Italy, he frequently visited his friend and fellow poet Percy Bysshe Shelley. Later in life Byron joined the Greek War of Independence fighting the Ottoman Empire and died leading a campaign during that war, for which Greeks revere him as a folk hero. He died in 1824 at the age of 36 from a fever contracted after the first and second sieges of Missolonghi.

His only legitimate child, Ada Lovelace, was a founding figure in the field of computer programming based on her notes for Charles Babbage's Analytical Engine. Byron's extramarital children include Allegra Byron, who died in childhood, and possibly Elizabeth Medora Leigh, daughter of his half-sister Augusta Leigh.

George Gordon Byron was born on 22 January 1788, on Holles Street in London, England – his birthplace is now supposedly occupied by a branch of the department store John Lewis.

Byron was the only child of Captain John Byron (known as 'Jack') and his second wife Catherine Gordon, heiress of the Gight estate in Aberdeenshire, Scotland. Byron's paternal grandparents were Vice-Admiral John Byron and Sophia Trevanion. Having survived a shipwreck as a teenage midshipman, Vice Admiral John Byron set a new speed record for circumnavigating the globe. After he became embroiled in a tempestuous voyage during the American Revolutionary War, John was nicknamed 'Foul-Weather Jack' Byron by the press.

Byron's father had previously been somewhat scandalously married to Amelia, Marchioness of Carmarthen, with whom he had been having an affair – the wedding took place just weeks after her divorce from her husband, and she was around eight months pregnant. The marriage was not a happy one, and their first two children – Sophia Georgina, and an unnamed boy – died in infancy. Amelia herself died in 1784 almost exactly a year after the birth of their third child, the poet's half-sister Augusta Mary. Though Amelia died from a wasting illness, probably tuberculosis, the press reported that her heart had been broken out of remorse for leaving her husband. Much later, 19th-century sources blamed Jack's own "brutal and vicious" treatment of her.

Jack then married Catherine Gordon of Gight on 13 May 1785, by all accounts only for her fortune. To claim his second wife's estate in Scotland, Byron's father took the additional surname "Gordon", becoming "John Byron Gordon", and occasionally styled himself "John Byron Gordon of Gight". Byron's mother had to sell her land and title to pay her new husband's debts, and in the space of two years, the large estate, worth some £23,500, had been squandered, leaving the former heiress with an annual income in trust of only £150. In a move to avoid his creditors, Catherine accompanied her profligate husband to France in 1786, but returned to England at the end of 1787 to give birth to her son.

The boy was born on 22 January in lodgings at Holles Street in London, and christened at St Marylebone Parish Church as "George Gordon Byron". His father appears to have wished to call his son 'William', but as her husband remained absent, the young Byron's mother named him after her own father George Gordon of Gight, who was a descendant of James I of Scotland, and who had died by suicide some four years earlier, in 1779.

Catherine moved back to Aberdeenshire in 1790, and Byron spent part of his childhood there. His father soon joined them in their lodgings in Queen Street, but the couple quickly separated. Catherine regularly experienced mood swings and bouts of melancholy, which could be partly explained by her husband's continuingly borrowing money from her. As a result, she fell even further into debt to support his demands. One of these loans enabled him to travel to Valenciennes, France, where he died of a "long & suffering illness" – probably tuberculosis – in 1791.

When Byron's great-uncle, who was posthumously labelled the "wicked" Lord Byron, died on 21 May 1798, the 10-year-old boy became the sixth Baron Byron of Rochdale and inherited the ancestral home, Newstead Abbey, in Nottinghamshire. His mother proudly took him to England, but the Abbey was in an embarrassing state of disrepair and, rather than live there, she decided to lease it to Lord Grey de Ruthyn, among others, during Byron's adolescence.

Described as "a woman without judgment or self-command", Catherine either spoiled and indulged her son or vexed him with her capricious stubbornness. Her drinking disgusted him and he often mocked her for being short and corpulent, which made it difficult for her to catch him to discipline him. Byron had been born with a deformed right foot; his mother once retaliated and, in a fit of temper, referred to him as "a lame brat". However, Byron's biographer, Doris Langley Moore, in her 1974 book Accounts Rendered, paints a more sympathetic view of Mrs Byron, showing how she was a staunch supporter of her son and sacrificed her own precarious finances to keep him in luxury at Harrow and Cambridge. Langley-Moore questions 19th-century biographer John Galt's claim that she over-indulged in alcohol.

Byron's mother-in-law Judith Noel, the Hon. Lady Milbanke, died in 1822, and her will required that he change his surname to "Noel" in order to inherit half of her estate. He accordingly obtained a Royal Warrant, enabling him to "take and use the surname of Noel only" and to "subscribe the said surname of Noel before all titles of honour". From that point, he signed himself "Noel Byron" (the usual signature of a peer being merely the name of the peerage, in this case simply "Byron"). Some have speculated that he did this so that his initials would read "N.B.", mimicking those of his hero, Napoleon Bonaparte. Lady Byron eventually succeeded to the Barony of Wentworth, becoming "Lady Wentworth".

Byron received his early formal education at Aberdeen Grammar School in 1798 until his move back to England as a 10-year-old. In August 1799 he entered the school of Dr. William Glennie, in Dulwich. Placed under the care of a Dr. Bailey, he was encouraged to exercise in moderation but could not restrain himself from "violent" bouts of activity in an attempt to compensate for his deformed foot. His mother interfered with his studies, often withdrawing him from school, which arguably contributed to his lack of self-discipline and his neglect of his classical studies.

In 1801, he was sent to Harrow School, where he remained until July 1805. An undistinguished student and an unskilled cricketer, he nevertheless represented the school during the very first Eton v Harrow cricket match at Lord's in 1805.

His lack of moderation was not restricted to physical exercise. Byron fell in love with Mary Chaworth, whom he met while at school, and she was the reason he refused to return to Harrow in September 1803. His mother wrote, "He has no indisposition that I know of but love, desperate love, the worst of all maladies in my opinion. In short, the boy is distractedly in love with Miss Chaworth." In Byron's later memoirs, "Mary Chaworth is portrayed as the first object of his adult sexual feelings."

Byron finally returned in January 1804, to a more settled period, which saw the formation of a circle of emotional involvements with other Harrow boys, which he recalled with great vividness: "My school friendships were with me passions (for I was always violent)". The most enduring of those was with John FitzGibbon, 2nd Earl of Clare—four years Byron's junior—whom he was to meet again unexpectedly many years later, in 1821, in Italy. His nostalgic poems about his Harrow friendships, Childish Recollections (1806), express a prescient "consciousness of sexual differences that may in the end make England untenable to him." Letters to Byron in the John Murray archive contain evidence of a previously unremarked if short-lived romantic relationship with a younger boy at Harrow, John Thomas Claridge.

The following autumn, he entered Trinity College, Cambridge, where he met and formed a close friendship with the younger John Edleston. About his "protégé" he wrote, "He has been my almost constant associate since October, 1805, when I entered Trinity College. His voice first attracted my attention, his countenance fixed it, and his manners attached me to him for ever." After Edleston's death, Byron composed Thyrza, a series of elegies, in his memory. In later years, he described the affair as "a violent, though pure love and passion". This statement, however, needs to be read in the context of hardening public attitudes toward homosexuality in England and the severe sanctions (including public hanging) imposed upon convicted or even suspected offenders. The liaison, on the other hand, may well have been "pure" out of respect for Edleston's innocence, in contrast to the (probably) more sexually overt relations experienced at Harrow School.The poem "The Cornelian" was written about the cornelian that Byron had received from Edleston.

Byron spent three years at Trinity College, engaging in sexual escapades, boxing, horse riding, and gambling. While at Cambridge, he also formed lifelong friendships with men such as John Cam Hobhouse, who initiated him into the Cambridge Whig Club, which endorsed liberal politics, and Francis Hodgson, a Fellow at King's College, with whom he corresponded on literary and other matters until the end of his life.

While not at school or college, Byron lived at his mother's residence, Burgage Manor in Southwell, Nottinghamshire. While there, he cultivated friendships with Elizabeth Bridget Pigot and her brother John, with whom he staged two plays for the entertainment of the community. During this time, with the help of Elizabeth Pigot, who copied many of his rough drafts, he was encouraged to write his first volumes of poetry. Fugitive Pieces was printed by Ridge of Newark, which contained poems written when Byron was only 17. However, it was promptly recalled and burned on the advice of his friend the Reverend J. T. Becher, on account of its more amorous verses, particularly the poem To Mary.

Hours of Idleness, a collection of many of the previous poems, along with more recent compositions, was the culminating book. The savage, anonymous criticism it received (now known to be the work of Henry Peter Brougham) in the Edinburgh Review prompted Byron to compose his first major satire, English Bards and Scotch Reviewers (1809).Byron put it into the hands of his relative R. C. Dallas, and asked him to "…get it published without his name." Alexander Dallas suggested a large number of changes to the manuscript, and provided the reasoning for some of them. Dallas also stated that Byron had originally intended to prefix an argument to this poem, which Dallas quoted. Although it was published anonymously, that April R. C. Dallas wrote that "you are already pretty generally known to be the author". The work so upset some of his critics that they challenged Byron to a duel; over time, in subsequent editions, it became a mark of prestige to be the target of Byron's pen.

After his return from travels he entrusted R. C. Dallas, as his literary agent, with the publication of his poem Childe Harold's Pilgrimage, which Byron thought to be of little account. The first two cantos of Childe Harold's Pilgrimage were published in 1812 and were received with critical acclaim. In Byron's own words, "I awoke one morning and found myself famous." He followed up this success with the poem's last two cantos, as well as four equally celebrated "Oriental Tales": The Giaour, The Bride of Abydos, The Corsair, and Lara. About the same time, he began his intimacy with his future biographer, Thomas Moore.

Byron racked up numerous debts as a young man, owing to what his mother termed a "reckless disregard for money". She lived at Newstead during this time, in fear of her son's creditors. He had planned to spend some time in 1808 cruising with his cousin George Bettesworth, who was captain of the 32-gun frigate HMS Tartar, but Bettesworth's death at the Battle of Alvøen in May 1808 made that impossible.

From 1809 to 1811, Byron went on the Grand Tour, then a customary part of the education of young noblemen. He travelled with Hobhouse for the first year, and his entourage of servants included Byron's trustworthy valet, William Fletcher. Hobhouse and Byron often made Fletcher the butt of their humour. The Napoleonic Wars forced Byron to avoid touring in most of Europe; he instead turned to the Mediterranean. His journey enabled him to avoid his creditors and to meet up with a former love, Mary Chaworth (the subject of his poem "To a Lady: On Being Asked My Reason for Quitting England in the Spring"). Letters to Byron from his friend Charles Skinner Matthews reveal that a key motive was also the hope of homosexual experiences. Another reason for choosing to visit the Mediterranean was probably his curiosity about the Levant; he had read about the Ottoman and Persian lands as a child, was attracted to Islam (especially Sufi mysticism), and later wrote, "With these countries, and events connected with them, all my really poetical feelings begin and end."

Byron began his trip in Portugal, from where he wrote a letter to his friend Mr Hodgson in which he describes what he had learned of the Portuguese language: mainly swear words and insults. Byron particularly enjoyed his stay in Sintra, which he later described in Childe Harold's Pilgrimage as "glorious Eden". From Lisbon he travelled overland to Seville, Jerez de la Frontera, Cádiz, and Gibraltar, and from there by sea to Sardinia, Malta, Albania and Greece. The purpose of Byron's and Hobhouse's travel to Albania was to meet Ali Pasha of Ioannina and to see the country that was, until then, mostly unknown in Britain.

While in Athens, Byron met 14-year-old Nicolo Giraud, with whom he became quite close and who taught him Italian. It has been suggested that the two may have had a sexual affair.[53] Byron arranged to have Giraud enrolled in school at a monastery in Malta, and wrote him into his will, with a bequest of £7,000. (That will, however, was later cancelled.) Byron wrote to Hobhouse from Athens, "I am tired of pl & opt Cs, the last thing I could be tired of." Opt Cs refers to a quote from Petronius' Satyricon, "coitum plenum et optabilem," "complete intercourse to one's heart's desire," their shared code for homosexual experiences.

In Athens in 1810, Byron wrote "Maid of Athens, ere we part" for a 12-year-old girl, Teresa Makri (1798–1875).

Byron and Hobhouse made their way to Smyrna, where they cadged a ride to Constantinople on HMS Salsette. On 3 May 1810, while Salsette was anchored awaiting Ottoman permission to dock at the city, Byron and Lieutenant Ekenhead, of Salsette's Marines, swam the Hellespont. Byron commemorated this feat in the second canto of Don Juan. He returned to England from Malta in July 1811 aboard HMS Volage.

After the publication of the first two cantos of Childe Harold's Pilgrimage (1812), Byron became a celebrity. "He rapidly became the most brilliant star in the dazzling world of Regency London. He was sought after at every society venue, elected to several exclusive clubs, and frequented the most fashionable London drawing-rooms. During this period in England he produced many works, including The Giaour, The Bride of Abydos (1813), Parisina, and The Siege of Corinth (1815). On the initiative of the composer Isaac Nathan, he produced in 1814–1815 the Hebrew Melodies (including what became some of his best-known lyrics, such as "She Walks in Beauty" and "The Destruction of Sennacherib"). Involved at first in an affair with Lady Caroline Lamb (who called him "mad, bad and dangerous to know") and with other lovers and also pressed by debt, he began to seek a suitable marriage, considering – amongst others – Annabella Millbanke. However, in 1813 he met for the first time in four years his half-sister, Augusta Leigh. Rumours of incest surrounded the pair; Augusta's daughter Medora (b. 1814) was suspected to have been Byron's child. To escape from growing debts and rumours, Byron pressed in his determination to marry Annabella, who was said to be the likely heiress of a rich uncle. They married on 2 January 1815, and their daughter, Ada, was born in December of that year. However, Byron's continuing obsession with Augusta Leigh (and his continuing sexual escapades with actresses such as Charlotte Mardyn and others) made their marital life a misery. Annabella considered Byron insane, and in January 1816 she left him, taking their daughter, and began proceedings for a legal separation. Their separation was made legal in a private settlement in March 1816. The scandal of the separation, the rumours about Augusta, and ever-increasing debts forced him to leave England in April 1816, never to return.

After this break-up of his domestic life, and by pressure on the part of his creditors, which led to the sale of his library, Byron left England, and never returned. (Despite his dying wishes, however, his body was returned for burial in England.) He journeyed through Belgium and continued up the Rhine river. In the summer of 1816 he settled at the Villa Diodati by Lake Geneva, Switzerland, with his personal physician, John William Polidori. There Byron befriended the poet Percy Bysshe Shelley and Shelley's future wife, Mary Godwin. He was also joined by Mary's stepsister, Claire Clairmont, with whom he'd had an affair in London. Several times Byron went to see Germaine de Staël and her Coppet group, which turned out to be a valid intellectual and emotional support to Byron at the time.

Kept indoors at the Villa Diodati by the "incessant rain" of "that wet, ungenial summer" over three days in June, the five turned to reading fantastical stories, including Fantasmagoriana, and then devising their own tales. Mary Shelley produced what would become Frankenstein, or The Modern Prometheus, and Polidori produced The Vampyre, the progenitor of the Romantic vampire genre.The Vampyre was the inspiration for a fragmentary story of Byron's, "A Fragment".

Byron's story fragment was published as a postscript to Mazeppa; he also wrote the third canto of Childe Harold.

Byron wintered in Venice, pausing in his travels when he fell in love with Marianna Segati, in whose Venice house he was lodging, and who was soon replaced by 22-year-old Margarita Cogni; both women were married. Cogni could not read or write, and she left her husband to move in with Byron. Their fighting often caused Byron to spend the night in his gondola; when he asked her to leave the house, she threw herself into the Venetian canal.

1816, Byron visited San Lazzaro degli Armeni in Venice, where he acquainted himself with Armenian culture with the help of the monks belonging to the Mechitarist Order. With the help of Father Pascal Aucher (Harutiun Avkerian), he learned the Armenian language and attended many seminars about language and history. He co-authored Grammar English and Armenian in 1817, an English textbook written by Aucher and corrected by Byron, and A Grammar Armenian and English in 1819, a project he initiated of a grammar of Classical Armenian for English speakers, where he included quotations from classical and modern Armenian.

Byron later helped to compile the English Armenian Dictionary (Barraran angleren yev hayeren, 1821) and wrote the preface, in which he explained Armenian oppression by the Turkish pashas and the Persian satraps and the Armenian struggle of liberation. His two main translations are the Epistle of Paul to the Corinthians, two chapters of Movses Khorenatsi's History of Armenia, and sections of Nerses of Lambron's Orations.

His fascination was so great that he even considered a replacement of the Cain story of the Bible with that of the legend of the Armenian patriarch Haik. He may be credited with the birth of Armenology and its propagation. His profound lyricism and ideological courage have inspired many Armenian poets, the likes of Ghevond Alishan, Smbat Shahaziz, Hovhannes Tumanyan, Ruben Vorberian, and others.

In 1817, he journeyed to Rome. On returning to Venice, he wrote the fourth canto of Childe Harold. About the same time, he sold Newstead Abbey and published Manfred, Cain, and The Deformed Transformed. The first five cantos of Don Juan were written between 1818 and 1820. During this period he met the 21-year-old Countess Guiccioli, who found her first love in Byron; he asked her to elope with him.

Because of his love for the local aristocratic, young, newly married Teresa Guiccioli, Byron lived in Ravenna from 1819 to 1821. Here he continued Don Juan and wrote the Ravenna Diary and My Dictionary and Recollections. Around this time he received visits from Percy Bysshe Shelley, as well as from Thomas Moore, to whom he confided his autobiography or "life and adventures", which Moore, Hobhouse, and Byron's publisher, John Murray,[66] burned in 1824, a month after Byron's death. Of Byron's lifestyle in Ravenna we know more from Shelley, who documented some of its more colourful aspects in a letter: "Lord Byron gets up at two. I get up, quite contrary to my usual custom … at 12. After breakfast we sit talking till six. From six to eight we gallop through the pine forest which divide Ravenna from the sea; we then come home and dine, and sit up gossiping till six in the morning. I don't suppose this will kill me in a week or fortnight, but I shall not try it longer. Lord B.'s establishment consists, besides servants, of ten horses, eight enormous dogs, three monkeys, five cats, an eagle, a crow, and a falcon; and all these, except the horses, walk about the house, which every now and then resounds with their unarbitrated quarrels, as if they were the masters of it… . [P.S.] I find that my enumeration of the animals in this Circean Palace was defective … . I have just met on the grand staircase five peacocks, two guinea hens, and an Egyptian crane. I wonder who all these animals were before they were changed into these shapes."

In 1821, Byron left Ravenna and went to live in the Tuscan city of Pisa, to which Teresa had also relocated. From 1821 to 1822, Byron finished Cantos 6–12 of Don Juan at Pisa, and in the same year he joined with Leigh Hunt and Shelley in starting a short-lived newspaper, The Liberal, in whose first number The Vision of Judgment appeared. For the first time since his arrival in Italy, Byron found himself tempted to give dinner parties; his guests included the Shelleys, Edward Ellerker Williams, Thomas Medwin, John Taaffe, and Edward John Trelawny; and "never", as Shelley said, "did he display himself to more advantage than on these occasions; being at once polite and cordial, full of social hilarity and the most perfect good humour; never diverging into ungraceful merriment, and yet keeping up the spirit of liveliness throughout the evening."

Shelley and Williams rented a house on the coast and had a schooner built. Byron decided to have his own yacht, and engaged Trelawny's friend, Captain Daniel Roberts, to design and construct the boat. Named the Bolivar, it was later sold to Charles John Gardiner, 1st Earl of Blessington, and Marguerite, Countess of Blessington, when Byron left for Greece in 1823.

Byron attended the beachside cremation of Shelley, which was orchestrated by Trelawny after Williams and Shelley drowned in a boating accident on 8 July 1822. His last Italian home was in Genoa. While living there he was accompanied by the Countess Guiccioli, and the Blessingtons. Lady Blessington based much of the material in her book, Conversations with Lord Byron, on the time spent together there. This book became an important biographical text about Byron's life just prior to his death.

Byron was living in Genoa in 1823, when, growing bored with his life there, he accepted overtures for his support from representatives of the Greek independence movement from the Ottoman Empire. At first, Byron did not wish to leave his 22-year-old mistress, Countess Teresa Guiccioli, who had abandoned her husband to live with him. But ultimately Guiccioli's father, Count Gamba, was allowed to leave his exile in the Romagna under the condition that his daughter return to him, without Byron. At the same time that the philhellene, Edward Blaquiere, was attempting to recruit him, Byron was confused as to what he was supposed to do in Greece, writing: "Blaquiere seemed to think that I might be of some use-even here;—though what he did not exactly specify". With the assistance of his banker and Captain Daniel Roberts, Byron chartered the brig Hercules to take him to Greece. When Byron left Genoa, it caused "passionate grief" from Guiccioli, who wept openly as he sailed away. The Hercules was forced to return to port shortly afterwards. When it set sail for the final time, Guiccioli had already left Genoa. On 16 July, Byron left Genoa, arriving at Kefalonia in the Ionian Islands on 4 August.

His voyage is covered in detail in Donald Prell's Sailing with Byron from Genoa to Cephalonia. Prell also wrote of a coincidence in Byron's chartering the Hercules. The vessel was launched only a few miles south of Seaham Hall, where in 1815 Byron married Annabella Milbanke. Between 1815 and 1823 the vessel was in service between England and Canada. Suddenly in 1823, the ship's Captain decided to sail to Genoa and offer the Hercules for charter. After taking Byron to Greece, the ship returned to England, never again to venture into the Mediterranean. The Hercules was aged 37 when, on 21 September 1852, she went aground near Hartlepool, 25 miles south of Sunderland, the place where her keel had been laid in 1815. Byron's "keel was laid" nine months before his official birth date, 22 January 1788. Therefore in ship years, he was also 37 when he died in Missolonghi.

Byron initially stayed on the island of Kefalonia, where he was besieged by agents of the rival Greek factions, all of whom wanted to recruit Byron for their own cause. The Ionian islands, of which Kefalonia is one, were under British rule until 1864. Byron spent £4,000 of his own money to refit the Greek fleet. When Byron travelled to the mainland of Greece on the night of 28 December 1823, Byron's ship was surprised by an Ottoman warship, which did not attack his ship, as the Ottoman captain mistook Byron's boat for a fireship. To avoid the Ottoman Navy, which he encountered several times on his voyage, Byron was forced to take a roundabout route and only reached Missolonghi on 5 January 1824.

After arriving in Missolonghi, Byron joined forces with Alexandros Mavrokordatos, a Greek politician with military power. Byron moved to the second floor of a two-story house and was forced to spend much of his time dealing with unruly Souliotes who demanded that Byron pay them the back-pay owed to them by the Greek government. Byron gave the Souliotes some £6,000. Byron was supposed to lead an attack on the Ottoman fortress of Navpaktos, whose Albanian garrison were unhappy due to arrears in pay, and who offered to put up only token resistance if Byron was willing to bribe them into surrendering. However, Ottoman commander Yussuf Pasha executed the mutinous Albanian officers who were offering to surrender Navpaktos to Byron and arranged to have some of the arrears paid out to the rest of the garrison.[86] Byron never led the attack on Navpaktos because the Souliotes kept demanding that Byron pay them more and more money before they would march; Byron grew tired of their blackmail and sent them all home on 15 February 1824. Byron wrote in a note to himself: "Having tried in vain at every expense, considerable trouble—and some danger to unite the Suliotes for the good of Greece-and their own—I have come to the following resolution—I will have nothing more to do with the Suliotes-they may go to the Turks or the devil…they may cut me into more pieces than they have dissensions among them, sooner than change my resolution". At the same time, Guiccioli's brother, Pietro Gamba, who had followed Byron to Greece, exasperated Byron with his incompetence as he continually made expensive mistakes. For example, when asked to buy some cloth from Corfu, Gamba ordered the wrong cloth in excess, causing the bill to be 10 times higher than what Byron wanted. Byron wrote about his right-hand man: "Gamba—who is anything but lucky—had something to do with it—and as usual—the moment he had—matters went wrong".

To help raise money for the revolution, Byron sold his estate in England, Rochdale Manor, which raised some £11,250. This led Byron to estimate that he now had some £20,000 at his disposal, all of which he planned to spend on the Greek cause. In today's money Byron would have been a millionaire many times over. News that a fabulously wealthy British aristocrat, known for his financial generosity, had arrived in Greece made Byron the object of much solicitation in that desperately poor country. Byron wrote to his business agent in England, "I should not like to give the Greeks but a half helping hand", saying he would have wanted to spend his entire fortune on Greek freedom. Byron found himself besieged by various people, both Greek and foreign, who tried to persuade him to open his pocketbook for support. By the end of March 1824, the so-called "Byron brigade" of 30 philhellene officers and about 200 men had been formed, paid for entirely by Byron. Leadership of the Greek cause in the Roumeli region was divided between two rival leaders: a former Klepht (bandit), Odysseas Androutsos; and a wealthy Phanariot Prince, Alexandros Mavrokordatos. Byron used his prestige to attempt to persuade the two rival leaders to come together to focus on defeating the Ottomans. At the same time, other leaders of the Greek factions like Petrobey Mavromichalis and Theodoros Kolokotronis wrote letters to Byron telling him to disregard all of the Roumeliot leaders and to come to their respective areas in the Peloponnese. This drove Byron to distraction; he complained that the Greeks were hopelessly disunited and spent more time feuding with each other than trying to win independence. Byron's friend Edward John Trelawny had aligned himself with Androutsos, who ruled Athens, and was now pressing for Byron to break with Mavrokordatos in favour of backing the rival Androutsos. Androutsos, having won over Trelawny to his cause, was now anxious to persuade Byron to put his wealth behind his claim to be the leader of Greece. Byron wrote with disgust about how one of the Greek captains, former Klepht Georgios Karaiskakis, attacked Missolonghi on 3 April 1824 with some 150 men supported by the Souliotes as he was unhappy with Mavrokordatos's leadership, which led to a brief bout of inter-Greek fighting before Karaiskakis was chased away by April 6.

Byron adopted a nine-year-old Turkish Muslim girl called Hato, whose parents had been killed by the Greeks. He ultimately sent her to safety in Kefalonia, knowing well that religious hatred between the Orthodox Greeks and Muslim Turks was running high and that any Muslim in Greece, even a child, was in serious danger.[94] Until 1934, most Turks did not have surnames; Hato's lack of a surname was quite typical for a Turkish family at this time.

Byron pursued his Greek page, Lukas Chalandritsanos, with whom he had fallen madly in love, but the affections went unrequited. Byron spoiled the teenage Chalandritsanos outrageously, spending some £600 (the equivalent of about £24,600 in today's money) catering to his every whim over the course of 6 months and writing his last poems about his passion for the Greek boy. Chalandritsanos was only interested in Byron's money. When the famous Danish sculptor Bertel Thorvaldsen heard about Byron's heroics in Greece, he voluntarily resculpted his earlier bust of Byron in Greek marble.

Mavrokordatos and Byron planned to attack the Turkish-held fortress of Lepanto, at the mouth of the Gulf of Corinth. Byron employed a fire master to prepare artillery, and he took part of the rebel army under his own command despite his lack of military experience. Before the expedition could sail, on February 15, 1824, he fell ill, and bloodletting weakened him further. He made a partial recovery, but in early April he caught a violent cold; the therapeutic bleeding insisted on by his doctors exacerbated it. He contracted a violent fever and died in Missolonghi on 19 April.

His physician at the time, Julius van Millingen, son of Dutch–English archaeologist James Millingen, was unable to prevent his death. It has been said that if Byron had lived and had gone on to defeat the Ottomans, he might have been declared King of Greece. However, modern scholars have found such an outcome unlikely. The British historian David Brewer wrote that in one sense, Byron failed to persuade the rival Greek factions to unite, won no victories and was successful only in the humanitarian sphere, using his great wealth to help the victims of the war, Christian and Muslim, but this did not affect the outcome of the Greek war of independence.

Brewer went on to argue,

In another sense, though, Byron achieved everything he could have wished. His presence in Greece, and in particular his death there, drew to the Greek cause not just the attention of sympathetic nations, but their increasing active participation … Despite the critics, Byron is primarily remembered with admiration as a poet of genius, with something approaching veneration as a symbol of high ideals, and with great affection as a man: for his courage and his ironic slant on life, for his generosity to the grandest of causes and to the humblest of individuals, for the constant interplay of judgment and sympathy. In Greece, he is still revered as no other foreigner, and as very few Greeks are, and like a Homeric hero he is accorded an honorific standard epithet, megalos kai kalos, a great and good man.
