Proper retreat soldier backed put in place again (9)

I believe the answer is:

realigned

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

'in place again' is the definition.
I can't judge whether this definition defines the answer.

'proper retreat soldier backed' is the wordplay.
'proper' becomes 'real' (similar in meaning).
'retreat' becomes 'den' (both can mean a lair or hideout).
'soldier' becomes 'GI' (term for US soldier).
'backed' says the letters should be written in reverse.
'den'+'gi'='dengi'
'dengi' back-to-front is 'igned'.
'real'+'igned'='REALIGNED'

'put' acts as a link.

Can you help me to learn more?

(Another definition for realigned that I've seen is " Grouped again on a new basis".)

I've seen this clue in The Independent.
