The convicts transported on the Exmouth came from counties throughout England, Wales and Scotland - Glamorgan, Montgomery, Caernarnvon, Carmarthan, Jedburgh, Dumfries, Aberdeen, Glasgow, Edinburgh, Perth, Inverary, Stirling, Denbigh, Chester, Hertford, Essex, York, Lancaster, Warwick, Stafford, Worcester, Kent, Middlesex, Derby, Bristol, London, Surrey, Gloucester, Westminster, Salop, Lincoln, Nottingham, Bucks, Leicester, Northampton, Cambridge, Cumberland, Bedfordand and Shrewsbury. There were also those who had been court-martialled at Gibraltar, Chatham and Woolwich.
The first of the prisoners, one hundred in number were embarked on the Exmouth from the hulks Ganymede, Justitia and Discovery at Woolwich.
The remainder of the prisoners embarked at Sheerness where the vessel lay from 19th February until 2nd March. Convicts perform hard labour at the Woolwich Warren. The hulk on the river is the 'Justitia'. Prisoners were kept on board such ships for months awaiting deportation to Australia. The 'Justitia' was a 260 ton prison hulk that had been originally moored in the Thames when the American War of Independence put a stop to the transportation of criminals to the former colonies.
This was William Conborough Watt's third voyage as surgeon-superintendent on a convict ship. He had previously served on the convict ships Edward in 1829 and the Roslin Castle in 1830.
He kept a Journal from 11 January to 18 August 1831.
According to his Journal a total of 405 people were embarked on the Exmouth including 55 children and 59 ship's company.
The weather was exceedingly wet and boisterous making it necessary to keep the prisoners crowded below deck. The surgeon began treating prisoners while the ship lay at Sheerness in February.
At this time ophthalmia presented in the boys' prison where, according to the surgeon, fifty six of the offspring of the most dissolute and abandoned London vagrants were confined. Their filthy and slovenly propensities and habits aided by close confinement to prison and the damp atmosphere, which they inhaled, added to the difficulties of treating the disorder.
Many had been afflicted with bad eyes on board the Euralysis hulk. Two young men James Burnes and Thomas Knowles, both aged 15 suffered from catarrh and ophthalmia, occasioned they thought by being put to watch the swinging stoves while on the Euralysis hulk. There was also an outbreak of ophthalmia among the ships company and guard. 
The Guard consisted of 3 sergeants, 46 rank and file with their wives and families of the 87th Royal Irish Fusiliers under command of Captain Moore and Lieutenants Irwin and Middlemore
The Exmouth was the next convict ship to leave England for New South Wales after the departure of the Eleanor in February 1831. Adverse winds and tempestuous weather delayed the ship's final departure from England until the morning of the 24th March 1831.
On his previous voyages of the Edward in 1829 and the Roslin Castle in 1830, William C. Watt had treated the convicts with compassion and all his skill and this continued on the voyage of the Exmouth. His observations in the journal include references to the prisoners' mental health and the impact on their physical ailments.
On leaving England, he observed...
.......the prisoners enjoyed tolerable health but amongst them even a casual observer could not fail to discover many who, (amid the thoughtless devilry and careless indifference of their fellow prisoners) in a retired corner of the prison, were the victims of most agonising reflections. With feelings of deep contrition, they brooded over their dereliction from the paths of rectitude. Separated from relations friends and country, the companions of the vilest description of their species and objects of suspicion to the rest of mankind, labouring thus under this depressed state of mind which I have attempted to describe. Confined in the between decks of a prison ship crowded to excess by two hundred and ninety delinquents breathing air vitiated from the boisterous state of the weather rendering it impossible to open the air scuttles to admit of ventilation. Neglectful of personal cleanliness, upon a poor diet of salt animal food for the period of time and through such a variety of climate as a voyage to New South Wales requires, and without a ray of hope to cheer them on their arrival at their remote destination, many of the unfortunate beings from the commencement of the voyage gave themselves entirely up to despair and it was not without foreboding that I contemplated the serious nature of the charge entrusted to me.
Nor were my fears unfounded early in March scurvy made its appearance and progressively increased numbering amongst its most early victims those objects who, trained to habits of profligacy and debauchery with constitutions debilitated by every species of vice, I had observed most secluded and sensible of the miseries to which their follies had exposed them - with them the disease assumed its most inveterate form and required a variety of treatments the usual means prescribed in such cases having failed in procuring for them that relief which it afforded to others labouring under a milder form of the disorder. 
In all eighteen men suffered from scurvy and according to the surgeon all but three were cured with a solution of nitre and vinegar. The convicts suffered from many other complaints as well as scurvy, ranging from rashes and eruptions to tonsillitis, headache and melancholia.
On 25th April sixteen year old Peter Pollen suffered serious burns to his back and shoulder when a bucket of hot liquid was spilt over him as he lay in his bunk. He was kept in the hospital for a month. 
The Exmouth arrived in Port Jackson on 28th July 1831. One prisoner, Richard Beard had died at sea on the 28th May from Pythisis and three were sent to hospital on arrival.
The prisoners exhibited anything but a healthy appearance on their arrival and they had but barely recovered their strength of body and energy of mind at the period of their disembarkation after fifteen days liberal supply of fresh beef and vegetables. 
A muster was held on board by the Colonial Secretary on the 1st August 1831. The indents include name, age, education, religion, marital status, family, native place, trade, offence, when and where tried, sentence, previous convictions, physical description and who the prisoners were assigned to on arrival. There is also occasional information in the indents regarding relatives already in the country, dates of death, pardons and prior convictions. 
And so it is revealed that Thomas Whitehead died at Patrick Plains in 1833 and John Walker was executed at Norfolk Island in September 1834 and also that William Swallow was being returned once more to his place of punishment.
William Swallow first arrived as a convict in Van Diemen's Land on the Georgiana in 1829. He became infamous as one of the pirates who escaped in the brig Cyprus in 1829. Read about his adventures here. Although Francis McNamara did not arrived in the colony until 1832, he wrote a ballad about the Cyprus which became one of Australia's well known Folk Songs
Departure of the Exmouth
The Exmouth departed Sydney for Calcutta in September, however returned to port in consequence of adverse winds experienced while attempting to pass through Torres Strait. They left Sydney again in October.
Life in the Colony
Sixteen convict ships arrived in New South Wales in 1831. Many of the prisoners arriving on these vessels would have witnessed the bonfires in Sydney on 2nd December 1831, set alight to celebrate the arrival of the new Governor Sir Richard Bourke.
The punishment meted out to William Smith for drunkenness and resisting arrest was probably fairly typical of that other convicts experienced for committing minor transgressions of the law. Bushranger Henry Hughes who touched hand with some of the most notorious convicts in the colony, received a much harsher penalty and was transported to a penal colony for life.
Bushranger Herbert Owen may have been another who escaped the penalty of the law. Although his named was printed in the wanted lists for years, there is no record of his fate.
