Early life

Born in Scotland on 15 June 1792, he was son of John Mitchell of Carron Works and was brought up from childhood by his uncle, Thomas Livingstone of Parkhall, Stirlingshire.[3]

Peninsula War

On the death of his uncle, he joined the British army in Portugal as a volunteer in the Peninsula War, at the age of sixteen. On 24 June 1811, at the age of nineteen, he received his first commission as 2nd Lieutenant in the 1st Battalion 95th Rifles (later the Rifle Brigade / Royal Green Jackets). Utilising his skills as a draughtsman of outstanding ability, he was occasionally employed in the Quartermaster-General's department under Sir George Murray. He was present at the storming of the fortresses of Ciudad Rodrigo, Badajos and San Sebastian as well as the battles of Salamanca and the Pyrenees. Subsequently, he would receive the Military General Service Medal with bars for each of these engagements.

When the war was over Mitchell was selected to reside in Spain and Portugal for four years to complete sketches of the battlefields for the Military Depot.[4] His duties also included conducting several other important surveys which had been impossible to finish whilst operations were in progress in the field. On 10 June 1818, during this posting, Mitchell married Mary Blunt (daughter of General Richard Blunt)[2] in Lisbon and gained promotion to a company in the 54th Regiment.[5]

In the summer of 1819, he returned to Britain where he devoted himself to finishing the drawings, but with the cessation of the Government allowances he had to stop this work. The reductions in the military establishment which followed the withdrawing of the Army of Occupation from France forced Mitchell on to half-pay. It was not until much later, whilst Mitchell was in London between 1838 and 1840, that the work was completed. The finished drawings were published by the London geographer James Wyld in 1841 under the title Atlas containing the principle battles, sieges and affairs of the Peninsular War. Of high quality, it is the prime source for the topography of the war.[6]

New South Wales

In 1827, with the support of Sir George Murray, Mitchell became Assistant Surveyor General of New South Wales with the right to succeed John Oxley. Oxley died the following year, and on 27 May 1828, Mitchell became Surveyor General.[2] In this post he did much to improve the quality and accuracy of surveying – a vital task in a colony where huge tracts of land were being opened up and sold to new settlers. One of the first roads surveyed under his leadership was the Great North Road, built by convict labour between 1826 and 1836 linking Sydney to the Hunter Region. The Great South Road (now replaced by the Hume Highway), also convict-built, linked Sydney and Goulburn. He kept a record of his 'Progress in roads and Public Works in New South Wales to 1855',[7] including sketches and plans of Sydney, Emu Plains, the Blue Mountains, Victoria Pass, roads to Bathurst, Wiseman's Ferry, and indigenous Australians.[8]

As Surveyor General, Mitchell also completed maps and plans of Sydney, including Darling Point,[9] Point Piper,[10] the city,[11] and Port Jackson.[12] In 1834 he was commissioned to survey a map of the Nineteen Counties. The map he produced was done with such skill and accuracy that he was awarded a knighthood.[13] Around this time, a portrait of Mitchell was painted showing him in the uniform of Major of the 1st Rifle Brigade of the 95th Regiment, complete with whistle used to direct the movement of troops.[14]

During his tenure in New South Wales, Mitchell led four extensive and historically significant surveying expeditions into the interior of eastern Australia.

First expedition

In 1831 a runaway convict named George "The Barber" Clarke, who had lived with Wiradjuri people in the area for several years, claimed that a large river called Kindur flowed north-west from the Liverpool Ranges in New South Wales to the sea. Charles Sturt believed that the Murray-Darling system formed the main river system of New South Wales and Mitchell wanted to prove Sturt wrong. Mitchell formed an expedition consisting of himself, assistant surveyor George Boyle White and 15 convicts who were promised remission for good conduct. Mitchell took 20 bullocks, three heavy drays, three light carts and nine horses to carry supplies, and set out on 24 November 1831 to investigate the claim. On reaching Wollombi in the Hunter Valley, the local assistant surveyor, Heneage Finch, expressed a desire to join the expedition which Mitchell approved, provided he first obtain extra provisions and rendezvous later.[15]

The expedition continued northward, and having climbed the Liverpool Range on 5 December, they found an Aboriginal tribe who had fled from their home in the Hunter Valley and were suffering from what appeared to be smallpox. On 8 December they arrived at Quirindi and by 11 December the expedition had reached Wallamoul Station near Tamworth, the northern extent of white settlement at the time.[15]

Mitchell continued his northward push into uncolonised territory, guided by a local Gamilaraay man named "Mr. Brown". In mid December, near to where Boggabri now stands, they located the remains of a stockyard and huts built by George Clarke and his Aboriginal colleagues. By early January 1832 Mitchell's group was travelling along the Namoi River, by which stage Mr Brown had left them. Mitchell's party then headed north unguided but managed to reach the Gwydir River in mid-January where they found a small Aboriginal village of conical-roofed huts. They followed the Gwydir west and made it to the Barwon River by the end of the month. Mitchell came to the correct conclusion that the Barwon flowed into the Darling River and decided not to proceed any further.[15]

At this stage, Finch had finally caught up with the main group. Finch conveyed the news that the provisions he had obtained had been ransacked by Aboriginal people at Gorolei. Two men he had left to guard the supplies had also been killed. The immediate effect was that Mitchell decided to abandon the expedition and return south. The party retraced their path having tense but peaceful interactions with large groups of Gamilaraay people along way. They reached Gorolei on 18 February where Mitchell buried the bodies of the two killed men and salvaged some equipment. Aboriginal people approached the group laying down their spears and offering females to Mitchell's men in an apparent attempt at appeasement for the killings. Mitchell refused the offer but accepted their guidance on an easy way back to the Namoi River. Once back at Wallamoul, Mitchell placed White in charge of the main party, while he returned hastily to Sydney. He was satisfied that there was no truth about the river Kindur claimed by Clarke.[15] Fourteen years later, Mitchell revealed that the convicts had indulged in sexual relations with Aboriginal women.

Second expedition

Mitchell's next expedition was in 1835. The purpose was to explore the course of the Darling River from where Sturt had turned back in 1829, to where it joined the Murray River. There were 24 men in the party including Mitchell, James Larmer (assistant surveyor) as second in command, Richard Cunningham (colonial botanist) and 21 other men. The main party under Larmer left Parramatta on 9 March and rendezvoused with Mitchell at Boree near the township of Orange. From there, the expedition was guided through the Goobang Ranges by local Wiradjuri people toward the Bogan River. On 17 April 1835, Richard Cunningham wandered away from the party while looking for botanical specimens and went missing. The party, with the assistance of various local Aboriginal people, searched for him until 5 May, following Cunningham's tracks around the headwaters of the Bogan until they disappeared. Cunningham's dead horse, saddle, glove and fragments of his coat and map were all they found. Months later, a search party of military mounted police commanded by Lieutenant Henry Zouch of the first division, discovered that Cunningham had been killed by four Wiradjuri men and his bones were found and buried at Currindine.[16]

After the fruitless search for Cunningham, Mitchell decided to continue the expedition. He was assisted by a local unnamed elder who provided a guide called Tackijally. This man led Mitchell downstream along the waterholes adjacent to the Bogan River as far as Nyngan. Tackijally left them at this point and the group was soon involved in a brief confrontation after they startled an Aboriginal man at a waterhole. The man, who was shot in the hand, had his wounds dressed by the group and later departed. They proceeded down the Bogan, encountering several gatherings of people to which Mitchell gave tomahawks and pieces of an old sword. On 25 May the junction with the Darling River was reached. Here, on a high point of land which bore many Aboriginal grave sites, Mitchell decided to build a fort as he realised that they "had not asked permission to come there" and he needed a stockade for "stout resistance against any number of natives." He named it Fort Bourke in honour of the Governor, Richard Bourke.[16]

Two whale boats had been transported the whole distance on bullock drays and on 1 June Mitchell launched the boats on the Darling to transport the party downriver. However, the Darling became shallower and unnavigable resulting in the expedition resorting once again to overland progress.[17] They encountered many tribes as they headed south, with Mitchell documenting the agricultural practices of some, such as the harvesting of Panicum decompositum, and the large permanent dwellings of others. One clan appeared more hostile than others, kicking up dust and spitting at party members. Mitchell acknowledged that his group were "rather unceremonious invaders of their country" but inflamed tensions by firing a pistol at a tree. Mitchell wrote that "the more they saw of our superior weapons...the more they shewed their hatred and tokens of defiance." The party continued downriver, meeting with more friendlier locals, passing through villages and noting the construction of their tomb-sites.[16]

Just north of the Menindee Lakes, the expedition came across a large congregation of several tribes and Mitchell decided that continuing the exploration would be too dangerous. On 11 July, just as Mitchell had resolved to return to Sydney, shots were heard from a forage party up the river. Mitchell sent a further three armed men to the scene of the shooting and the firing continued. After more than an hour, some members of the group returned reporting that a skirmish had occurred over the possession of a kettle and at least three Aboriginal people had been shot dead, including a woman and her child. One of Mitchell's men had been knocked unconscious. The party then commenced their return via the outbound route with Mitchell deciding to avoid contact with the various tribes as much as possible. The "spitting tribe" attempted to burn down their camp on this return journey which resulted in Mitchell ordering shots to be fired over their heads. They arrived at Fort Bourke on 10 August and continued back along the Bogan River. Near Nyngan they met again with members of Tackijally's tribe who allowed Mitchell to walk through their cemetery at Milmeridien. Mitchell soon tired of the clan asking for food and ordered some of his men to march at them with bayonets. On 9 September they came to the upper reaches of the Bogan where they found a cattle-station had already been formed along their route by William Lee. The expedition arrived back at their starting point of Boree on 14 September.[16]

While Mitchell did not trace the Darling River to its junction with the Murray River, the course and terrain of the Bogan River and much of the Darling River had been charted.[18] The places where this and other Mitchell expeditions were most assailed by Aboriginal Australians, including the location of Cunningham's killing, are marked on an 1836 map produced by Mitchell.[19]

Third expedition

Piper

The goal of Mitchell's third expedition was to explore and survey the lower part of the Darling River, with instructions to head up the Murray River and then return to the settled areas around Yass. Second in command was assistant surveyor Granville Stapylton. A Wiradjuri guide named John Piper was also recruited and 23 convicts and ticket of leave men made up the rest of the party. The group set out from a valley near Mount Canobolas on 17 March 1836, and made their way to Boree and the Bogan River as on previous journeys, then veered south to the Lachlan River to approach the Darling from its southern end where it joined the Murray.[20]

The party travelled along the Lachlan, passing Condobolin and Lake Cargelligo, as John Oxley did in 1817. Piper was able to converse with tribes to learn where vital waterholes were, as the Lachlan was drying out. On 2 May an Aboriginal widow named Turandurey with her four-year-old daughter Ballandella from the Muthi Muthi tribe joined the expedition as a guide. She remembered Oxley from nineteen years earlier and Sturt as well, and knew the lower Lachlan. The Murrumbidgee River was reached on 12 May, but at a point downstream from the junction with the Lachlan.

The party camped while Mitchell took five men and went upstream to find the junction. Once found, they turned about and continued down the Murrumbidgee until 21 May when they were close to the junction with the Murray River. A depot was established at this point, so Mitchell left Staplyton and eight men to guard the stock, while he ventured downstream with fifteen men. On 24 May Mitchell noticed that Barkindji tribesmen from the Darling River were gathering in large numbers, and by 27 May the hostile intentions of these men became known, when local Murray River people told Piper that the Barkindji were planning to kill Mitchell and his men. Mitchell had to decide whether to wait for an attack, or plan a pre-emptive manoeuvre. His numbers were reduced, as Staplyton and eight men were still at the depot. He split his party again, leaving half the men to hide in the scrub in ambush, while he continued ahead with the carts. When the armed Barkindji warriors approached, the convict Charles King, who was involved in the earlier killings, fired first without waiting for orders. The tribesmen fled into the river and Mitchell's two groups reunited on the shore and continued to shoot at the people for up to 15 minutes.[21] Around 75 shots were fired[22] with Piper later being told that seven Barkindji were killed and four wounded.[23] Mitchell wrote about the loss of life in his journal, describing the Barkindji as "treacherous savages", and detailing how his men had chased them away, "pursuing and shooting as many as they could."[24] This section was withheld from Mitchell's report when it was released to the public in Sydney.[25][26] Mitchell named the hill near to where the mass-shooting occurred Mount Dispersion and it is now the heritage-listed Mount Dispersion Massacre Site Aboriginal Place.[27]

The expedition continued and on 31 May they reached the junction of the Darling and Murray rivers. Mitchell travelled up the eastern side of the Darling for some distance, and when he was certain that it was the same river he had explored in 1835, he turned back and headed upstream on the Murray to join Stapylton at the depot. The reunited expedition now travelled south-east following the Murray, crossed the river on 13 June and named Swan Hill on 21 June. At the end of June the country had improved considerably, so Mitchell chose to leave the Murray to investigate better looking lands to the south-west. Upon climbing the 300-foot Pyramid Hill, he was so impressed with the country he saw, he named it Australia Felix. In early July the party crossed the Loddon River, and made their way in a south-westerly direction which brought them to the Grampians, and later to the mouth of the Glenelg River on the coast. It was now August, so Mitchell altered direction towards Portland and the south-east. When Portland was reached on 29 August, Mitchell was surprised to find an established farm manned by the Henty brothers, Edward and Frank. There were several whaling boats on Portland Bay as well.

After a brief sojourn, the expedition commenced the return to Sydney in a north-easterly direction, meeting few Aboriginal people on the way, though they were aware of being watched. On 17 September, in order to speed his return, Mitchell split the party in two once more taking 14 men with him, and leaving the remainder with Stapylton to follow with the bullocks and drays. The young girl Ballandella went with Mitchell, while Turandurey remained with the rear party. On 30 September, Mitchell climbed and named Mount Macedon, from the summit of which he had a view of Port Phillip. Progress was slow due to wet ground, and the Murrumbidgee was not reached until 24 October. When Mitchell arrived in Sydney in early November he was received with great joy. However, when the remainder of his party arrived two weeks later, rumours circulated about the mass killing on the Murray. He subsequently faced a Legislative Council Inquiry in December 1836, receiving an official rebuke. Ballandella joined Mitchell's family of eight other children and learnt to read and write, but was left by Mitchell when he returned to England. Ballandella later married and raised a family at Sackville where she died around the age of thirty.[28]

Fourth expedition

Mitchell's fourth expedition was into Queensland in 1845–46. He was convinced that a significant river must flow north-west into the Gulf of Carpentaria, this being the main thrust of the endeavour.[29]

On 15 December 1845 Mitchell started from Boree (Buree in Mitchell's journal) with a large party including Edmund Kennedy as second in command (later speared to death at Escape River near Cape York). He struck the Darling River above Fort Bourke then continued to the Narran River, the Balonne, and the Culgoa. On 12 April 1846 he came to a natural bridge of rocks on the main branch of the Balonne which he called St. George Bridge, now the site of the town of St George. Kennedy was left in charge of the main body here, and was instructed to follow on slowly while Mitchell pushed ahead with a few men. Mitchell followed the Balonne to the Maranoa, and the Cogoon (now called Muckadilla Creek, near Roma). This rivulet led him to a magnificent pastoral district in the midst of which stood a solitary hill that he named Mount Abundance. He then crossed a low watershed to the Maranoa and awaited Kennedy's arrival. Kennedy rejoined Mitchell on 1 June 1846.[29]

Leaving Kennedy for a second time, he set out on an extensive excursion of more than four months.[30] Mitchell traversed the country at the head of the Maranoa and sighted the Warrago River. Keeping north over the watershed, he traversed the Claude and Nogoa rivers, then reached the Belyando River, an upper reach of the Burdekin River.[29] This had already been visited by Ludwig Leichhardt on his expedition to Port Essington on 2 April 1845. Intensely mortified to find that he was on a tributary of the Burdekin River, and approaching the ground already trodden by Leichhardt, he returned to the head of the Nogoa and struck west, after dividing his party and forming a stationary camp. He continued west, making a new finding which he was certain was the fabled north-west river. In honour of the sovereign of the time he decided to call it Victoria River.[29] Having run out of time, he turned back towards the main party. It was here that Mitchell first noticed the well known grass that bears his name. On the homeward journey he trekked along the Maranoa River to St.George Bridge, arriving in Sydney 20 January 1847.[31] Later that year, Kennedy proved beyond doubt that the Victoria did not continue north-west, but turned south-west and joined Cooper Creek. He renamed the watercourse the Barcoo River from a name mentioned by local Aboriginal people.[29]

Later career

Engraving of Major Sir Thomas Mitchell

In 1837, Mitchell sought 18 months leave from his position and in May he left Sydney for London. During his leave, he published an account of his explorations called Three Expeditions into the Interior of Eastern Australia: with descriptions of the recently explored region of Australia Felix, and of the present colony of New South Wales.[32] Mitchell sought additional periods of leave and finally arrived back in Australia in 1841. Mitchell left Sydney again in March 1847 on another period of leave. By the time he arrived back in mid-1848, he had published his Journal of an Expedition into the Interior of Tropical Australia, in search of a route from Sydney to the Gulf of Carpentaria.[1]

Mitchell's journals proved a rich source for historians and anthropologists, with their close and sympathetic observations of the Aboriginal peoples he had encountered. These publications made him the most celebrated Australian explorer of his day.[33] But he was a difficult man to get on with, made evident by this passage made by Governor Charles Augustus FitzRoy:

"It is notorious that Sir Thomas Mitchell's unfortunate impracticability of temper and spirit of opposition of those in authority over him misled him into frequent collision with my predecessors."[33]

In a by-election for the Electoral district of Port Phillip in April 1844, Mitchell was elected to the New South Wales Legislative Council.[2] He found it difficult to separate his roles of government employee and elected member of the legislature, and after only five months he resigned from the Legislative Council.[1][2]

Mitchell is also remembered as the last person in Australia to challenge anyone to a duel. In September 1851, Mitchell issued a challenge to Sir Stuart Alexander Donaldson because Donaldson had publicly criticised excessive spending by the Surveyor General's Department. The duel took place in Sydney on 27 September with both duellists missing their marks.[34] The French 50 calibre pistols used in the duel are in the collection of the National Museum of Australia.[35]

Ophir gold fields

In 1851, Mitchell was instructed by Governor FitzRoy to make a report on, and survey of, 'the extent and productiveness of the goldfield reported to have been discovered in the County of Bathurst.'[5][36] He travelled west during winter to visit the Ophir gold diggings, accompanied by his son, Roderick, and Samuel Stutchbury the government geologist.[36]

In June 1851 Mitchell selected the site for the township of Ophir. W.R. Davidson plotted a survey of the ground and Mitchell planned the streets and allotments for the town.[37]

Mitchell returned with a collection of specimens from the diggings, mostly quartz, with 48 of these stored in a wooden chest.[38] His report of the goldfields was presented to the Legislative Council in February 1852.[5]

Story of the "bomerang" propeller

The search for a method of screw propulsion of ships intrigued many inventors during the latter half of the 18th century and the beginning of the 19th. An Englishman, K. P. Smith, patented a screw propeller in 1836, and shortly afterwards Captain John Ericsson, formerly an officer of the Swedish army, patented another.

On his travels, Mitchell must have been evolving the idea of his boomerang propeller—he spelled it "bomerang", while newspapers used "bomarang" and "boomerang." The first test was made in the Sydney Harbour in May 1852, an iron propeller being fitted to the "screw-steamer" Keera. The results of this trial were considered satisfactory, the ship's progress being calculated on two runs at 10 and a little over 12 knots,[39] and Sir Thomas Mitchell took his Invention to England. In 1853 the propeller was fitted to the Genova, and a trial was conducted on the Mersey. Then the Admiralty gave it a test on HMS Conflict. The Genova ran at 9.5 knots as against 8.5 with a screw propeller, and the Conflict 9.25 knots as against the screw propeller 8.75, and at a lower engine speed. The "boomerang" propeller can be simply described as a "screw" propeller with much of the blades close to the shaft, which contribute little to propulsion but much to drag, cut away,[40] a principle which is well understood today.

Family life

Carthona, Mitchell's home in Darling Point

Thomas Mitchell and Mary had twelve children: Livingstone, Roderick, Murray, Campbell, Thomas, Richard, Georgina, Maria, Emily, Camilla, Alicia, Blanche.[5] Georgina and Maria died young, and Murray before 1847. Roderick became a Commissioner of Crown Lands and head of the Border Police in the Liverpool Plains district.[41] Roderick was drowned and Campbell died during the last years of Mitchell's life.[5]

His family enjoyed a privileged upbringing, and Blanche Mitchell, his youngest daughter, recorded her daily activities and social life in childhood diaries and notebooks.[42] Her sister Emily married George Edward Thicknesse-Touchet, 21st Baron Audley.

In 1841, Mitchell completed his new Gothic home, Carthona, on the water's edge in Darling Point, Sydney.[42] Following Mitchell's death, his family moved to Craigend Terrace in Woolloomooloo.[42]

Death

Thomas Mitchell Plaque, Camperdown

In July 1855 a Royal Commission was appointed to inquire into the New South Wales Survey Department. Before its report was published, Mitchell contracted a chill while surveying the line of road between Nelligen and Braidwood. He developed a severe attack of bronchitis and died a few days later at Carthona at Darling Point at 5:15 pm 5 October 1855.[43] Newspapers of the day commented:

"For a period of twenty-eight years Sir Thomas Mitchell had served the Colony, much of that service having been exceedingly arduous and difficult. Among the early explorers of Australia his name will occupy an honoured place in the estimation of posterity."

He is buried at Camperdown Cemetery, Newtown, with his grave being maintained by the Seniors Group of Surveyors.[44]

Naming

Some of the places Mitchell named on his expeditions were: the Avoca River, Balonne River, Belyando River, Campaspe River, Cogoon River, Discovery Bay, Glenelg River, Grampians, Maranoa River, Mount Arapiles, Mount King, Mount Macedon, Mount Napier, Mount William, Nyngan, Pyramid Hill, St George, Swan Hill and Wimmera River.

Commemoration

The grave of Major Mitchell, Surveyor General

Because of his contributions in the surveying and exploration of Australia, Mitchell is commemorated by having numerous localities or objects across Australia being named after him. These include:

Mitchell is also the namesake in the highest honour of the New South Wales Surveyors Awards, the Sir Thomas Mitchell Excellence in Surveying Award.
