In 1834 the prisoners to be transported on the Blenheim were incarcerated in the Surprize Hulk at Cork.
The prison had been established about ten years previously and the following report was written in 1824 -
This prison has been arranged in a very complete manner, in the Surprize frigate, and affords good accommodation for 350 convicts. The state of the hulk with respect to accommodation, dietary, cleanliness, and interior regulation, we found to be very satisfactory. The ship has been extremely healthy.
The officers all seem to perform their duty well; but we should recommend very strongly that a schoolmaster should be appointed, and a latitude given to Mr. Hollingsworth, the local inspector, to provide books. This officer would be much inclined to forward the instruction of the convicts, and under the superintendence of the chaplains, much good effect might be expected. One of the reasons which has been assigned for want of instruction on board the hulk, is the shortness of the stay of the convicts; but it is to be considered that almost all these prisoners have come from a county gaol in which a school was established, many of them from scenes of real improvement, and that they are therefore prepared at once to be placed in the class of readers, and that a temporary suspension of ail endeavours to instruct, might much counteract any improvement which may have been acquired. Some of the prisoners are employed in carpenter's work, making and repairing prison dresses, and occasionally picking oakum........Report of the Committee of the Society for the Improvement of Prison Discipline 1824
The Freeman's Journal reported on Saturday 19th July 1834 -
Two hundred and fifty male convicts from Limerick, Galway, Cork, Waterford, Kerry, Clare, Tipperary and Castlebar were embarked in the Blenheim at Cove and proceeded for Botany Bay on Monday. A detachment of the 50th regiment is on board.
Surgeon James Wilson
James Wilson kept a Medical Journal from 30 May to 28 November 1834 ....
On 7th July, I went on board the Surprize convict hulk at the Cove of Cork, and was present at the inspection of the convicts by a Medical Officer sent from Dublin for that purpose. There was also present the Medical Officer belonging to the Hulk. I objected to receive some of the prisoners and offered to receive two others. One was said by the Surgeon to be blind and in fact he was led to the cabin door and then led away as a person unfit for embarkation on account of total loss of vision said to be of long standing. The Officer from Dublin seeing on the list that his crime was sheep stealing had him called back, and he and I took the man into open light to examine his eyes. This he resisted by keeping the palpebra so permanently closed that no efforts of our fingers could separate them; this power of the muscles no doubt acquired from long continued action, he having I was afterwards informed employed it for 13 months. Being defeated in ascertaining the state of the globe of the eye but quite certain the globe in both eyes were entire from the prominence of the palpebra, I got a spatula which I introduced with some force it being contrary to his will, between the eyelids and separated them with that, and I saw that vision was perfect in both eyes. I told him I would receive him on board and recommended his having his eyes open when he came or I would punish him at the gangway.
The other case was said to be chronic rheumatism of long standing. This man was stripped and examined by the Dublin Officer and myself when we found him to be a powerful muscular man at the advanced age he said of 76. The appearance of the prisoners as a body was that of being very cleanly in their persons and their strength equal to the seamen who offer themselves as volunteers for His Majesty's Navy.
On the 8th July we embarked 200 of the above convicts, one of them Daniel Sughrue, the blind man who was led yesterday he came out the boat and up the ships side without assistance, on his getting on board, I advised him to look in my face, he did so with the eyes half opened when I told him unless he opened both that instant and looked in my face, my promise of flogging him would be carried into execution on this he opened both his eyes and looked me full in the face showing two eyes perfectly natural.
About the same time ten free settlers sons of convicts were embarked. These boys were messed and slept in the small prison with the convicts, three of these lads were nearly destitute of clothing and the head of one swarming with vermin.......
