I would like to apologise for the slave trade.

I'm not really an expert, but I can safely say, that turfing a patio will NOt work. The turfs will die in a matter of days.

You would be much better off getting your slaves to dig up the patio first, then lay a bit of top-soil, then the turfs.

Perhaps they could use the flagstones to construct some kind of makeshift shelter to live in, at the end of the garden?

details, details. don't bother me with details.
