Make your own armed men go to the ship (7)
I believe the answer is:
possess
'make your own armed men go' is the definition.
I can't tell whether this defines the answer.
'to the ship' is the wordplay.
'to the' becomes 'posse' (I can't explain this - if you can you should give a lot more credence to this answer).
'ship' becomes 'SS' (prefix in ship names eg SS Great Britain).
'posse'+'ss'='POSSESS'
Can you help me to learn more?
(Other definitions for possess that I've seen before include "Have ownership of" , "Own, keep" , "Consume" , "Have - control" , "Have as one's own" .)
