Backlash from soldiers with wind (6)
I believe the answer is:
recoil
'backlash' is the definition.
('recoil' can be a synonym of 'backlash')
'soldiers with wind' is the wordplay.
'soldiers' becomes 're' (Royal Engineers).
'with' says to put letters next to each other.
'wind' becomes 'coil' (coiling is a kind of winding**).
're'+'coil'='RECOIL'
'from' acts as a link.
(Other definitions for recoil that I've seen before include "Draw back in fear or disgust" , "Jerk back" , "Flinch; rebound" , "Backward jerk of a gun when it's fired" , "Start back like a gun on firing" .)
