Burton knew more about the conspiracy than she had told him. He threatened to throw her in jail if she did not tell him more, so she testified further. There was rising fear about slaves and poor whites' combining for insurrection. Burton swore the three members of the Geneva Club met frequently at Hughson's home, had talked about burning the fort and town, and the Hughsons had agreed to help them. Another person suspected in the fires was "Margaret Sorubiero, alias Salingburgh, alias Kerry, commonly called Peggy", or the "Newfoundland Irish" beauty. She was a prostitute who serviced blacks. The room she lived in was paid for by Caesar, with whom she had a child. Although Burton's testimony did not prove that any crime had been committed, the grand jury was so afraid that more fires would occur that they decided to believe her. The board of inquiry requested the lieutenant-governor to issue a proclamation offering a reward to anyone providing information leading to the conviction of anyone setting fire to any dwelling or storehouse in the city: £100 to a white person, £45 to a free black or Indian, and £20 and freedom to a slave. Such prices attracted more testimony. On May 2, the court found Caesar and Prince guilty of burglary and condemned them to death. The next day seven barns caught fire. Two blacks were caught and immediately burned at the stake. On May 6, the Hughsons and Peggy were found guilty of burglary charges. Peggy, "in fear of her life, decided to talk." Some of the blacks who had been imprisoned in the dungeons also decided to talk. Two who did not talk were Caesar and Prince, who were hanged on May 11. Trials Having gathered witnesses, Horsmanden started the trials. Kofi (Cuffee) and another slave Quaco (Quack) were the first to be tried. They were convicted, although each of their masters defended them. Respectable white men whose testimony normally would have been given considerable weight, they stated that each of the slaves had been at home the evening in question. The slaves were convicted anyway. Immediately before being sentenced to being hanged on May 30, they confessed and identified dozens of other so-called conspirators. Moore asked to save them as future witnesses, but the officers of the court decided against it because of the rage of the crowd. Each of the slaves was hanged.
