Hulk Surprise (334 convicts), located at Cork
Hulk Essex (400 convicts) located at Dublin
Cork Penitentiary (females) (120 convicts).
The total of 854 prisoners noted in the Return is a little short of Charles Bateson total in The Convict Ships (845), but is close and may not account for those who were rejected by the surgeon as being too ill to survive the voyage.
The Hercules convicts came from counties and cities throughout Ireland including Carlow, Down, Antrim, Armagh, Roscommon, Louth, Fermanagh and Dublin. The Belfast Newsletter reported the method used to convey some of them to the hulk at Dublin.....
On Thursday 13th May 1830 three cart loads of convicts, who were sentenced to transportation at last Assizes, passed through Belfast, escorted by a party of soldiers, on their way from Carrickfergus to Dublin. On turning Linen-Hall street, they gave three hearty cheers, which were as heartily repeated by the populace. 
Crimes committed included rape, burglary, highway robbery, house breaking, stealing pigs & horses, pocket picking, embezzlement and desertion. Some were convicted of committing murder at the Macken Riot at Fermanagh which took place in July 1829. The story of the "Macken Fight," written by Michael McManus, YDNA Project.......
The New Reformation of 1827 was a Protestant movement against Catholic emancipation in Ireland and it had sprung up at the end of 1826 in County Cavan. Apart from denying them emancipation many Protestants wanted to convert Catholics and.... 450 Catholics were converted in Cavan where they publicly renounced their faith in various Protestant churches. The movement obviously caused much friction in the communities and one side acted as badly as the other - Protestants tried to force Catholics to conform and Catholics tried to persuade ex-Catholics to return to Catholicism. The New Reformation movement spread to Fermanagh and Lord Enniskillen was one of its great supporters. According to one account, he ordered his Catholic tenants to attend Protestant church services or be evicted from their land. Three families, the Duffys, the Maguires and the MacManus', must have refused because they were evicted and settled in the hilly terrain at Ruscaw. So, at the time of the Macken Riot there was a polarisation of the usual religious and political conflict which had been going on in Ireland for many centuries.
The Freeman's Journal tells of the fate of some of the prisoners after the trials -
The Battle of Macken - The Montgomeries and McManus' who were sentenced by Judge Jebb to be hanged at Enniskillen on Thursday last and whose lives the Duke of Northumberland has been graciously pleased to spare, by commuting their sentence to transportation for life, were brought up on the outside of the Cavan day coach yesterday and sent off to the hulk at Kingstown. We trust the ferment excited in Fermanagh by the trials of those men, and the unfortunate McManus who was executed last week, will induce his Grace to postpone the trial of the other fifteen Catholics who are in prison for the same crime of which they were found guilty. 
Select here to find the names of the men who were convicted of murder at Fermanagh on 23rd March 1830.
Altogether twenty-eight men were conveyed from Enniskillen jail to the Kingstown hulk - 14 were the Macken rioters; 3 for maliciously throwing a horse down a precipice, 3 for horse and cow stealing; 3 for burglary, 2 for attempt at highway robbery, 2 for cutting down Colonel Barton's plantation, and 1 for stealing wearing apparel etc., from a care taker of Sir Henry Brooke's. 
SURGEON WILLIAM MARTIN
William Martin kept a Medical Journal from 22 May to 22 November 1830, during which time the ship was employed in a passage from Deptford to Kingston and from there to Sydney in New South Wales......
On 13 June 1830 the Hercules arrived in Kingston harbour. A few days prior to her sailing, some of the convicts on board the Essex hulk, stationed at Kingston, set fire to that vessel in three places, close to the water. The flames were fortunately suppressed, and all on board, being upwards of three hundred prisoners, were transmitted, for better security to the Hercules, which had then but recently arrived in the harbour, to convey some of them to New South Wales. 
The Standard reported the incident on 17 June-
The Essex Hulk stationed in Kingston harbour is on fire and nearly consumed! A number of convicts are on board. The sloop of war Trincolo, and the revenue brig Shamrock, with some transports, have sent all their boats to the assistance of the unfortunate prisoners; and a strong force of horse and foot police from the city has been ordered off to Kingston. The Essex was an American Frigate of 36 guns, and was taken during the late war at Valparaiso, by his Majesty's frigate Phoebe, of 36 guns commanded by Captain Hillier.
Two hundred men were embarked on the Hercules. Of these nearly 60 were under 20 years of age; about one half from 20 to 30; and the remainder between that and 70. The city and county of Dublin furnished more than one half of the number including a large proportion of the boys, several of whom, even of the boys, had made serious inroads on their constitutions by their previous irregularities and excesses. 
The guard consisted of a detachment of the 17th regt., who were accompanied by 4 women and 3 children under the Command of Major J.W. Bouverie and Lieutenant C.W. Finch. Select here to find convict ships bringing detachments of the 17th regiment.
By the time the Hercules departed Dublin on 3rd July 1830, the surgeon had time to establish a little order and cleanliness amongst the prisoners...........
Immediately after breakfast, when the weather permitted, they were turned up leaving a sufficient number below to clean the prison though roughly, and then joined their companions as soon as their work was properly done. They were kept up during the day and frequently dined on the deck in fine weather. During the voyage the same system was adhered to, only it was necessary to shelter them as much as practicable, from the sun within the tropics, and from the cold on proceeding to the Southward. We had little serious sickness during the voyage but among men so little accustomed to the use of animal food of any description, the change of diet, on proceeding to sea, naturally produced considerable and very general constipation of the bowels, and on approaching the Tropics many slight cases of fever appeared. On rounding the Cape of Good Hope on the 15th Sept and afterwards proceeding to the Southward, the weather became cold and the thermometer, at one time came down so low as 40 degrees. Catarrhal affections then prevailed, but generally were so slight as to require little or no medical treatment.
The Hercules arrived in Port Jackson on Sunday 31st October or 1st November 1830. One hundred and ninety-nine prisoners arrived, one man by the name of Michael White having died on the passage out. The Hercules brought news of the death of King George the Fourth.
The Captain gave the prisoners an excellent character. They were mustered on board by the Colonial Secretary Alexander Macleay on 4th November 1830 and were to be landed on Monday 15th November 1830.

He was apprehended at Roslea in Fermanagh, by one of the police at that station. After his escape from prison, he got off in a merchant vessel for America, and rendered himself so useful on board by assisting in working the ship, that his passage money was returned to him, and he engaged as a sailor.
