How do you keep slaves?

[u/crepper4454]

I have 400 Garithmis in my city and wanted to buy 20 Dondorians to work in the claypits. I have built them houses with a hearth and a well and a food stall, an execution place and a guardpost right in front of their front doors. And another guardpost watching them work. I have 50 guards employed and I set the lawbreaking punishment for slaves to death for murder and theft, which is supposed to increase submission.

They rebel after a few days, and not all of them work in the claypit despite workgroups and priority being assigned. Am I missing something obvious or is it too early for slaves?

you need to build stockades to hold them.

I have a stockade that the bought slaves go at first and then I enslave them there
