Lieutenant Colonel Sir Arthur Henry McMahon GCMG GCVO KCIE CSI KStJ (28 November 1862 Simla, India – 29 December 1949 London, United Kingdom), was a British Indian Army officer and diplomat who served as the High Commissioner in Egypt from 1915 to 1917. He was also an administrator in the British Raj and served twice as Chief Commissioner of Balochistan. McMahon is best known for the McMahon-Hussein Correspondence with Hussein bin Ali, Sharif of Mecca, the McMahon Line between Tibet and India and the Declaration to the Seven in response to a memorandum written by seven notable Syrians. After the Sykes-Picot Agreement was published by the Bolshevik Russian government in November 1917, McMahon resigned. He also features prominently in T.E. Lawrence's account of his role in the Arab Revolt against the Ottoman Empire during World War I, Seven Pillars of Wisdom.

Background

McMahon was the son of Lieutenant-General Charles Alexander McMahon, FRS, FGS (1830–1904), a geologist and Commissioner of both Lahore and Hisar in Punjab, India, and who, like his father Captain Alexander McMahon (born 1791, Kilrea, County Londonderry, Ireland) had been an officer with the East India Company. The McMahons are the Gaelic clan of Mac Mathghamhna who had come originally from the medieval Irish kingdom of Airgíalla or Oriel in South Ulster/North Leinster, where they reigned from around 1250 until about 1600.

Sir Henry McMahon's own family had settled in the Downpatrick area of County Down before his great-grandfather, The Rev. Arthur McMahon, moved to Kilrea, where he was minister to the local Presbyterian congregation between 1789 and 1794: a prominent Irish Republican, The Rev. Mr McMahon was a member of the National Directory of the Society of United Irishmen and one of their colonels in Ulster during the Irish Rebellion of 1798. He apparently fought at the battles of Saintfield and Ballynahinch and after the rebels' overall defeat had been able to flee to France where he served with Napoléon's Irish Legion.

It is said that he was captured by the British during the Walcheren Campaign of 1809, and though sent to England, was later able to return to France where in June 1815 he eventually died fighting, it is believed, at either Ligny or of Waterloo.

Career

McMahon was commissioned a Lieutenant in the Indian Staff Corps in the 1880s and was appointed a Companion of the Most Eminent Order of the Indian Empire (CIE) in 1894. By 1897, he had been promoted to captain and was appointed a Companion of the Most Exalted Order of the Star of India (CSI) in that year. He was promoted Major in the army in July 1901. He was knighted as a Knight Commander of the Most Eminent Order of the Indian Empire (KCIE) in 1906 and promoted to the rank of Lieutenant Colonel in 1909. In 1911, on the occasion of the Delhi Durbar, he was foreign secretary of the British government in India. The King made him a Knight Grand Cross of the Royal Victorian Order (GCVO), an award in his own gift. He spoke Persian, Afghan, and Hindoostani, an aptitude for languages that led also to Arabic.

Sir Henry was appointed to the post of High Commissioner in Egypt in 1915. When he arrived by train Sir Ronald Storrs described him as "quiet, friendly, agreeable, considerate and cautious", although later in his career Storrs and others were not so charitable. He was made a Knight of Grace of the Most Venerable Order of the Hospital of Saint John of Jerusalem (KStJ).

McMahon replaced Sir Milne Cheetham, briefly acting for Kitchener. Although a temporary appointment it became a permanent post, for an experienced political administrator. McMahon was appointed British High Commissioner in Cairo, to replace Lord Kitchener who had become War Secretary in London. With the approval of Kitchener and Foreign Secretary Sir Edward Grey, McMahon began a long correspondence with Sharif Husayn, the Ottoman-appointed ruler of the Hijaz to use the Bedouin tribes under his control to support the Egyptian Expeditionary Force in overthrowing the Ottomans.

Sir Gilbert Clayton, Aubrey Herbert, Storrs and others of the intelligence community approved of McMahon's pro-Arabist policy from 1916 onwards. McMahon sat on the plan to use the Sharif to support British for six months. But it was Sir Reginald Wingate who persuaded McMahon that the Arabs were ready, able and willing for Cairo to support Husayn in an effort to overthrow the Ottomans and establish a pan-Arab state made up of Ottoman Arab lands in the Middle East. Storrs thought the diplomacy was "in every way exaggerated." He was appointed a Knight Grand Cross of the Most Distinguished Order of Saint Michael and Saint George (GCMG) in 1916 upon his retirement from the British Indian Army.

By May 1916, Turkish troops had arrived in Mecca, McMahon received a telegram from Abdullah ibn Husayn, Sharif Husayn's son, that the Movement was ready. McMahon despatched the oriental secretary, Storrs to London with a team of intelligence experts. The British decision to land at the Dardanelles, instead of Alexandretta, and to allow French Syria founded by the Sykes-Picot Agreement to exist at all, irritated McMahon. In 1920, he was awarded the Order of El Nahda, 1st Class, from the King of the Hejaz. In 1925, he was promoted to a Knight of Justice of the Most Venerable Order of the Hospital of Saint John of Jerusalem (KStJ).
