Eldred Pottinger (1811–1843), Anglo-Indian soldier and diplomatist, son of Thomas Pottinger of Mountpottinger, County Down, and Charlotte Moore. He was educated at Addiscombe Military Academy, and entered the Bombay Artillery in 1827. After some years of regimental duty he was appointed to the political department under his uncle, Colonel (afterwards Sir) Henry Pottinger.
In 1837 he made a journey through Afghanistan in disguise. Arriving at Herat, he found it threatened by a Persian army (with which were some Russian officers) and immediately made himself known to the Afghan commander, offering his services. The attack which soon followed was conducted with the greatest vigour, but the defence, inspired by Pottinger, was invariably successful, and after a year the siege was raised.
For this great service Pottinger was thanked by the governor-general, the earl of Auckland, made brevet-major, and also received the C.B. He was also appointed political officer at Herat. In. 1841 he was political officer in Kohistan when the revolt against Shah Shuja broke out there. Taking refuge with the Gurkha garrison of Charikar, Major Pottinger stood a siege of fourteen days, and then made an adventurous retreat to Kabul. Less than a fortnight after his arrival Sir William Macnaghten was murdered, and Pottinger succeeded to his position as envoy to the Afghan court. The apathy of the military leaders made resistance hopeless, and it only remained to negotiate for the withdrawal of the British army. Pottinger himself was one of the hostages handed over to Akbar Khan, and thus escaped the near-total massacre of the retreating British and Sepoy troops in the retreat from Kabul to Jelalabad in January, 1842. Released, after some months of captivity, by Sir George Pollock's army, he returned to India, and a year later died while visiting Hong Kong.
