House Gale's men (7)
I believe the answer is:
windsor
'house' is the definition.
(royal house)
'gale's men' is the wordplay.
'gale's' becomes 'wind's' (I've seen this in other clues).
'men' becomes 'OR' (military abbreviation for other ranks).
'winds'+'or'='WINDSOR'
(Other definitions for windsor that I've seen before include "Chair < for house" , "Type of soap" , "Weekend residence of the British royal family" , "Knot type; royal castle" , "Thames town" .)
