I want to know the answer to the following question:
Who instructed the Governor of New South Wales Thomas Brisbane to send the worst convicts to Norfolk Island?
All the background I'm provided with is that "The convicts detained have long been assumed to be a hardcore of recidivists, or 'doubly-convicted capital respites' – that is, men transported to Australia who committed fresh colonial crimes for which they were sentenced to death, and were spared the gallows on condition of life at Norfolk Island.". Is that enough to answer the question?
