Newman and his defence committee needed to locate the victims and return them to England. A number of the victims were found and Maria Giberne, a friend of Newman, went to Italy to return with them to England. Achilli, on hearing that witnesses were being brought, arranged for the trial to be delayed. This put Newman under great strain as he had been invited to be the founding rector of the proposed Catholic University in Dublin and was composing and delivering the lectures that would become "The Idea of a University".
