Restrained by some Parisian, crowd reverts to peaceful mode (6)

I believe the answer is:

demobs

I'm a little stuck... Click here to teach me more about this clue!

'reverts to peaceful mode' is the definition.
I can't tell whether this defines the answer.

'restrained by some parisian crowd' is the wordplay.
'restrained by' indicates putting letters inside.
'some parisian' becomes 'des' ('some' in French).
'crowd' becomes 'mob' (mob can mean a crowd of people).
'des' placed around 'mob' is 'DEMOBS'.

Can you help me to learn more?
