the "John Adventure" entered Port Royal it was seized by the governor for landing goods without entry, contrary to the Acts of Navigation, and on complaint of the master of the vessel that he had been robbed by Deane and other privateers, Sir Henry Morgan was ordered to imprison the offenders. The lieutenant-governor, however, seems rather to have encouraged them to escape,[376] until Deane made so bold as to accuse the governor of illegal seizure. Deane was in consequence arrested by the governor, and on 27th April 1676, in a Court of Admiralty presided over by Lord Vaughan as vice-admiral, was tried and condemned to suffer death as a pirate.[377] The proceedings, however, were not warranted by legal practice, for according to statutes of the twenty-seventh and twenty-eighth years of Henry VIII., pirates might not be tried in an Admiralty Court, but only under the Common Law of England by a Commission of Oyer and Terminer under the great seal.[378] After obtaining an opinion to this effect from the Judge of the Admiralty, the English Council wrote to Lord Vaughan staying the execution of Deane, and ordering a new trial to be held under a proper commission about to be forwarded to him.[379] The Governor of Jamaica, however, upon receiving a confession from Deane and frequent petitions for pardon, had reprieved the pirate a month before the letter from the council reached him.[380] The incident had good effect in persuading the freebooters to come in, and that result assured, the governor could afford to bend to popular clamour in favour of the culprit. In the latter part of 1677 a standing commission of Oyer and Terminer for the trial of pirates in Jamaica was prepared by the attorney-general and sent to the colony.[381]
