Lieutenant-Colonel Henry Dumaresq (1792-1838) was a military officer of the era of the Napoleonic Wars, colonial government official, and early colonial settler of New South Wales. He was associated with the Upper Hunter Valley and Port Stephens, and was one of the first to take up land around Armidale.
Early life and military service
Dumaresq was the son of John Dumaresq, a Shropshire colonel, and Anne Jones. He attended the Royal Military College, Great Marlow, and became a military officer. The Dumaresq family has strong connections with the Channel Islands, particularly Jersey.
Henry joined the 9th Regiment. He served in the Peninsula War—he was wounded at Villa Muriel—and at New Orleans in the War of 1812, and then at the Battle of Waterloo, during which—while a Captain on the staff of Lieutenant General John Byng as aide-de-camp—he was severely wounded at Hougoumont. Although wounded and not revealing that wound, he rode across the battlefield to deliver a vital message, on the morale and ammunition supply of the Hougoumont garrison, to the Duke of Wellington. He then collapsed, fell from his horse, and was placed in the care of the Duke's personal surgeon. He was promoted to Brevet Major for his actions at Waterloo and, two years later, was made a Lieutenant Colonel. Unusually for the time, Dumaresq earned his promotions, through zeal and courage, without need of purchasing his commissions. A musket ball remained lodged in his lungs for the rest of his life.
New South Wales
He was the brother-in-law of Ralph Darling. When Darling was appointed Governor of New South Wales, in 1824, Dumaresq was already serving as Darling's Military Secretary in Mauritius.
He was appointed Darling's Private Secretary, and arrived in New South Wales, five months before Darling, to prepare for Darling's arrival. He was subsequently appointed clerk of the Executive Council. His brothers, William and Edward, also followed Darling and their sister, Eliza, to Australia. William went to New South Wales, but Edward went to Tasmania—then called Van Diemen's Land—where he became acting Surveyor-General, in 1825.
Darling had been appointed with the objective of restoring discipline to the penal colony, after what was seen by the British government of the time as the relatively lax rule of the two previous Governors, Lachlan Macquarie and Thomas Brisbane. As such, he had the support of the 'Exclusives' faction in the colony, who had sought to undermine Brisbane's administration.
Darling tended to rely upon like-minded military men for his administration, and it was soon subject to criticism for nepotism and favouritism. This criticism could not be stifled, as Darling's predecessor, Thomas Brisbane, had ended press censorship, creating in effect press freedom before Darling arrived in 1824. Darling's subsequent attempt to control the press through new legislation failed, because the Chief Justice, Francis Forbes, advised that the measures were not compatible with the laws of England.
The Dumaresq brothers, Henry in particular, became a lightning rod for criticism of Darling's administration. He fought a duel with barrister and newspaper editor Robert Wardell in 1827, over an article in Wardell's newspaper, The Australian, titled "How-e to live by plunder", with both men leaving uninjured.
Later in 1827, he went to England, where he married Elizabeth Sophia Butler-Danvers, half-sister to the 5th Earl of Lanesborough. He and his new wife returned to New South Wales, in 1829, bringing with them a royal charter for an expanded Legislative Council. The couple had four daughters and three sons.
By the time that Darling's term as governor ended in 1831, Henry and his brother William had been granted substantial landholdings in New South Wales. Henry had a property near modern-day Muswellbrook, that he named St Heliers. He also operated a large sheep run in the New England region, Saumarez, from 1835; this vast tract of land of 40,000 hectares was beyond the Nineteen Counties. Not only was Saumarez taken from local Aboriginal people, but its occupation was not legal, even under the colonial law of the time. It was a 'squatting' run, until legitimised by the payment of a £10 annual licence fee in 1837.
