Bring back forces in front of gallery (9)

I believe the answer is:

reinstate

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

'bring back' is the definition.
(I've seen this before)

'forces in front of gallery' is the wordplay.
'forces in front of' becomes 'reins' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'gallery' becomes 'tate' (Tate Modern, Tate Britain etc).
'reins'+'tate'='REINSTATE'

Can you help me to learn more?

(Other definitions for reinstate that I've seen before include "Restore, put back" , "Put back in place" , "Restore to previous position" , "Re-establish" , "Put back in position" .)

I've seen this clue in The Hindu.
