Following the brief Pentridge or
Pentrich rising on the night of 9/10 June 1817 on the Nottinghamshire and
Derbyshire border, three rebel leaders, Jeremiah Brandreth, Isaac Ludlam and William Turner, were captured. They were subsequently tried for treason, hanged and posthumously beheaded. Others who had taken part in the uprising were transported to Australia. A few days after the uprising, in a series of astonishing articles in the
Leeds Mercury beginning on 14 June 1817,
Edward Baines alleged that the Pentrich events had in fact been incited by the earlier activities of "Oliver the Spy", who had been known to the rebels as "London delegate" William Oliver. Baines also alleged that the authorities, had known from Oliver that the rising was about to happen, but had let it go ahead in order to advance their own political ends. Baines revealed that Oliver was actually W. J. Richards, "a spy" working for Lord Sidmouth's Home Office. The newspaper article of 14 June was read out almost in its entirety by
Francis Burdett on the 16th in the House of Commons, where it gave rise to sensational debates which were repeated several times. The accusation, of course, was that Oliver the Home Office informer was, in fact, the moving spirit in the Pentrich disturbances, and that without him they would not have taken place at all. Although Oliver was not present at the uprising, debate as to his role and responsibility for it has continued ever since. While the use of informers had become routine on the part of magistrates during the Luddite period, the practice was regarded by a wide section of public opinion as being alien to the spirit of English law, and the exposure in the
Leeds Mercury of Oliver’s role, as an
agent provocateur, astounded public opinion.
Earl Fitzwilliam, the Lord Lieutenant of the West Riding of Yorkshire, wrote to Lord Sidmouth on 14 June about the uprising, squarely blaming Oliver for what had happened: There certainly prevails very generally in the country a strong and decided opinion that most of the events that have recently occurred in the country are to be attributed to the presence and active agitation of Mr. Oliver. He is considered as the
main spring from which every movement has taken its rise. All the mischievous in the country have considered themselves as subordinate members of a great leading body of revolutionists in London, as cooperating with that body for one general purpose, and in this view to be under its instructions and directions, communicated by some delegate appointed for the purpose. Had not then a person pretending to come from that body and for that purpose, made his appearance in the country, it is not assuming too much to say that probably no movement whatever would have occurred - it does not follow that a dangerous spirit could not have been found lurking in any breast, but that that spirit would not have found its way into action.
E. P. Thompson in
The Making of the English Working Class (1963) more succinctly called Oliver the "archetype of the Radical Judas". ==Move to Cape Town==
