The Susan was built at Calcutta in 1813. 
The convicts transported on the Susan were tried counties in England, Scotland and Wales - Cambridge, Berks, Bristol, Bucks, Somerset, Hereford, Northumberland, Stafford, Leicester, Surrey, Cumerland, Durham, Warwick, Norfolk, Worcester, Derby, Warwick, Gloucester, Bedford, Lincoln, York, Lancaster, Essex, Chester, Nottingham, London, Kent, Stafford, Middlesex, Radnor, Aberdeen, Edinburgh, Perth, Glasgow, Monmouth. There were also soldiers who had court-martialled at Chatham, Hull Citadel, Knightsbridge Barracks, Salford Barracks, Fort George - North Britain and Carlisle Castle.
The Susan departed London on 10th March 1834.
They put into Madeira in consequence of the death at sea a few days previously of Mr. John Issett, the Surgeon Superintendent, who had embarked at London. Surgeon Archibald Ross joined the ship at Madeira.
Surgeon Archibald Ross
Archibald Ross kept a Medical Journal and sick book from 24 March 1834 to 26th July 1834.
In his first entry on 24th March he noted the names of several boys who were all fine healthy looking lads but who had been afflicted dreadfully with the itch, some of them for months; others caught it when they joined the Susan. As part of their treatment, they were put into one large berth away from the rest of the boys.
Archibald Ross kept a lengthy detailed account of the illnesses experienced on board.
He remarked in his concluding notes that the seven scorbutic patients were all slightly afflicted with swellings of the lower extremities and stiffness of the joints; their gums were spongy and irritable, the breath offensive. In some of the cases the symptoms appeared only one or two days before reaching Port Jackson. He gave lemon juice and wine which he thought in many instances arrested the progress of the disease, while in other cases they did not appear to effect the least change in the complaint. During the whole voyage no epidemic or contagious disease prevailed at any time. Diarrhoea proved fatal in four instances. The fatal cases occurred in patients labouring under scurvy. 
The Susan arrived in Port Jackson on 8 July 1834 with 292 male prisoners, eight having died on the passage out.
On arrival in Sydney ten convicts were immediately sent to the hospital on shore

The Guard consisted of Lieut. Henry Gunter of 50th regiment.; Lieut. Bunbury 21st regiment.; and 29 rank and file of the 50th regiment., with 5 women and 4 children.
Henry Gunter kept a Journal on the voyage from Gravesend to Sydney, Feb.-July, 1834 in which there are many references to Henry Bunbury. The volume also contains Gunter's journal kept on a voyage to New Zealand on the Alligator, Aug.-Oct. 1834. This expedition followed the wreck of the Harriet and the imprisonment and murder of its crew and passengers. The journal describes the landing at Wymattie and an attack on a village.

Lieutenant Gunter and Captain Edward Johnstone also of the 50th had volunteered in the rescue of Betty Guard and crew of the Harriet.  This rescue and the ensuing massacre was the first action by British troops on New Zealand soil
