The story of Pip and Abel Magwitch in "Great Expectations" comes to mind.

Many interesting stories about escaped prisoners. One who had been sentenced to the Australian colonies and was taken on Mauritius is told in court records of New South Wales.
Badderly and Howard

I have only glanced at the records, but a new song, or added verses for Isle of France by Nic Jones, can be imagined.

Many prisoners from Bengal and other Asian colonies were taken to Mauritius. In 1815, five years after the British took Mauritius, 700 Bengali prisoners were taken there to work. Many Malay prisoners also ended up there.
Repatriation of the Asians was considered but, I believe, never accomplished.
