6671. 'With all their [other] service in which they made them serve with rigour' means the aim to bring them under their control by the use of many methods, without showing them any mercy. This is clear from the meaning of 'service' as the aim to bring under their control, as above in 6666, 6668, 6670, and in many ways, since the words 'all their service' are used; and from the meaning of 'rigour' as without mercy, dealt with in 6667.
