SURGEON ROBERT ARMSTRONG
Robert Armstrong kept a Medical Journal from 1st September 1820 to 15 March 1821. 
The Guard consisted of a detachment of 24th regiment., under orders of Lieut. Isaacson of 47th regiment. Soldiers treated by the surgeon included Private Edward Newell and Corporal Potter.
Passengers included Mrs Huff and Joseph Priestly.
Many of the adult prisoners who had been held on the Justitia Hulk were embarked on 20th September 1820. Robert Armstrong was treating them for excoriation where their irons had rubbed and minor ailments such as headache and loss of appetite soon after they arrived on the vessel. There were about fifteen prisoners under the age of sixteen, some of whom were held on the Retribution hulk and embarked on the Dick on the 6th October.
The Dick departed England on 4th November 1820.
The surgeon treated the older convicts kindly......Several of the prisoners were considerably advanced in years and whose health seemed impaired by their confinement to salt provisions have at different times been victualled in the Hospital twice a day and given substitutes for the salted food. By a general diet and a glass of wine occasionally their complaints generally disappeared in a few days when they returned to their own messes. 
Samuel Jackson (60) William Keeley (50), Jonathon Little (64), Robert Wenman (50) were the oldest prisoners on board.
Illnesses treated by the surgeon during the voyage included Catarrhs, Tinea Capitis, Tonsillitis, Debility, Enteritis, Erysipelas, Nephritis, Cystitis, Mania, rheumatism, fevers and scurvy. There were also six accidents.
Convicts treated during the voyage included John Denne, Samuel Jackson, Daniel Woodhall, Joseph Thompson, John Griffiths, Thomas Tonks, Benjamin Wellington, John Foran, Charles Franter, William Bond, Edward Bailey, John Hammond, Michael Robins, Adam Hulme, Thomas Bexon, Joseph Finch, William Bradley, John Scothern, James Hutchings, Michael Sullivan, William Green, Daniel Smeeton, Joseph Goddard, Thomas Parrott, John Williams and John Ford. 
The Dick arrived in Port Jackson on 12 March 1821 with 140 male prisoners in good health, none having died on the passage out.
INSPECTION OF CONVICTS
Governor Macquarie often inspected the prisoners who arrived on various vessels and the Sydney Gazette reported that on Thursday 15th March, His Excellency the Governor inspected the prisoners. Their appearance was a sufficient testimony, independent of their grateful acknowledgements of the kindness and humanity with which they had been treated on the voyage. His Excellency was pleased to direct their distribution in the usual manner.
The prisoners of the Dick were the last to be inspected by Governor Macquarie. Until Governor Macquarie's departure from the colony on the Surry in 1822, Lieut-Colonel Erskine undertook these duties.
THE DICK IN SYDNEY HARBOUR
There were a couple of incidences mentioned in the newspapers while the Dick lay in harbour - the first a serious accident....Some guns were being discharged on board, one of which hung fire; an unfortunate man was directed to sponge it, in consequence; when, lamentable to relate, the gun went off, taking with it the poor man's left arm, and part of his right side. He was immediately conveyed to the General Hospital.
In May the Dick was lying in the stream and was hailed by two men alongside who declared themselves to be almost drowning. A boat was sent to their assistance and they were found to be two prisoners who had swam from Dawes' Point with the intention of secreting themselves on board to escape from the Colony. They were soon lodged in custody and returned to shore.
DEPARTURE OF THE DICK FROM SYDNEY
When the Dick departed the colony bound for England Robert Armstrong returned on her. Also on the return voyage were William Hunibell, First Officer; Andrew Thompson, Second Officer; Henry Rogers, Third Officer.
