Thomas Shuldham O'Halloran

[3] O'Halloran entered the Royal Military College, Sandhurst (or Marlow[1]) in 1808 and at 16 he was commissioned into the 17th Foot and sailed for India.

On 1 August 1821 he married Miss Anne Goss of Dawlish, Devonshire, who died in 1823 in Calcutta, leaving two children.

[1] In 1824 he was ordered with the left wing of the 44th to Chittagong, where he arrived early in June, and was appointed paymaster, quartermaster, and interpreter.

On 30 October he was appointed brigade-major to Brigadier-General Dunkin, C.B., who commanded the Sylket division of the army during the Burmese war, and served on his staff until his death in Nov. 1825.

On 10 July 1834[3] he married Miss Jane Waring, of Newry, County Down, and retired on half-pay in October of that year.

[6][7] On 22 August 1840, after several days of interviews, investigations and a drumhead court-martial, two Milmenrura men were publicly hanged on the Coorong in front of 65 people from their tribe.

Gawler's ordering of a drumhead court-martial and the executions was not well received by the London authorities and contributed to his removal as governor.
