However, Banks backed William Bligh to be installed as the new governor of New South Wales and to crack down on the New South Wales Corps (or Rum Corps), which made a fortune on the trading of rum. This brought him in direct confrontation with post-Rum Rebellion "de facto" leaders such as John Macarthur and George Johnston. This backing led to the Rum Rebellion in Sydney, whereby the governor was overthrown by the two men. This became an embarrassment for Sir Joseph Banks, also, because years earlier, he campaigned that John Macarthur not be granted 10,000 acres of land near Sydney in the cow pastures, which was later granted by Lord Camden. The next governor, Lachlan Macquarie, was asked to arrest Macarthur and Johnston, only to realise that they had left Sydney for London to defend themselves. He was humiliated that Macarthur and Johnston were acquitted from all charges in London and both later returned to Sydney.
