Spreul returned from Holland in order to take his wife and children to Rotterdam. On 12 November 1680, he was apprehended by men looking for Donald Cargill, and being brought before the Council, was examined, and afterwards put to the torture before a Committee of their number. Not getting him to confess what they desired by torturing him in the new boot, they sent for the old one, and tortured him over again; and being equally unsuccessful with it, Dalziel alleged that the hangman favoured him; upon which the hangman said, he struck with all his might, and bade him take the mallet himself to do it better. On 2 March 1681, Spreul was indicted before the High Court of Justiciary on the charge of treason and rebellion, for alleged accession to the insurrection at Bothwell Bridge. The proof, however, failed, and a verdict of not proven was returned by the jury. Spreul's lawyer was Lockhart; those who did not recognise the courts generally did not employ lawyers. Upon this, instead of being liberated, he was still kept prisoner; and, on pretext of being present at field conventicles he was fined £500 sterling, and sent to the Bass, by an act of Privy Council, July 14, 1681. The order for transport is recorded as 16 August 1681. Here he continued for nearly six years. The act of Council for his liberation is dated 12 May 1687. He was the last prisoner who was released from the Bass. He survived the Revolution many years.
