HMS Anson departed Plymouth 1 October 1843 with 506 male prisoners. Passenger Captain Cocknaft with soldiers women and children. In all 830 people.
This was the largest number of convicts to have arrived in one ship and the Anson caused quite some interest on her arrival on 4th February 1844.......
Our splendid wharfs were crowded with promenaders on Sunday afternoon, to obtain a sight of H.M.S. Anson, once a 72 line of battle ship, and which has often carried the thunder of Britain amongst her foes. How different now her destiny! - employed as a receptacle for those degenerate Englishmen who have been spurned from the bosom of society. By this arrival 500 men have been added to our convict population.
The Anson is the largest vessel which has ever been in our harbour, and is commanded by Captain Coghlan, half brother as we understand to Mr. Driscoll, the respected Manager of the Colonial Bank. With prisoners, guard, crew and passengers , she has nearly a thousand souls on board. Mr. Forster a son of the A.P.M. of Brighton acted as chaplain on the voyage out. The Anson is an old vessel and masted with the spars of one of the old 42's her own spars being too heavy for a merchant crew to handle properly. She left Plymouth on the 1st October, and put into Rio Janeiro, where she remained 14 days.
The Anson is to be employed as a hulk for the reception of female probationers. The Troops on board consisted of part of the 51st, 58th 96th and 99th regiments.
