5). Seizure of the Trial - On the night of the 12th September 1816 ten prisoners of the Guildford together with two men from the Fanny and another from the Baring made a desperate bid to escape from the Colony.

On 12th January 1817 six soldiers embarked at Newcastle on the Lady Nelson commanded by Thomas Whyte to investigate a report of a wreck fifty miles to the north of Port Stephens and ascertain the fate of the vessel. (Thomas Whyte, master mariner had arrived as a convict on the Baring in 1815). They discovered part of the wreck on 14th on the beach of a deep and extensive bay in latitude 30 20' South. They learned from natives in the vicinity that the Trial had been wrecked and some of the men constructed a boat out of the materials of the wreck in which a large party once more went out to sea. Others had taken to the bush, among whom was a woman with a young child of whom not a single trace could be found.
The soldiers spent several days exploring the bushland in the vicinity to ascertain the fate of the passengers. They could not positively establish whether the small vessel made from the Trial sank or only disappeared from the view of the black spectators on shore. The Captain, passengers and crew, had endeavoured to make their way towards Newcastle, but no account had been further received from them. There were rumours of a woman who had stowed away on the Trial and was living with the natives in a most distressing state, however in February 1817 Richard Palmer wrote to the Sydney Gazette regarding this woman claiming that she was a relative of his and that she had not secreted herself but had a regular clearance for the Derwent where her husband was in the employ of Simeon Lord. He offered a reward of twenty pounds to any person finding her. In 1826 an anonymous correspondent to the Monitor claimed to have knowledge of the woman who escaped from the wreck of the Trial and was sojourning with a tribe of Aboriginal natives with her daughter about 12 or 13 years old. She was married to one of the tribe by whom she had two children and acted as a midwife to the matrons of the tribe. He received his information from a native of a tribe near Liverpool Plains.
