Money divided by male soldiers in that place (7)
I believe the answer is:
therein
'in that place' is the definition.
(I've seen this before)
'money divided by male soldiers' is the wordplay.
'money' becomes 'tin' (I've seen this before).
'divided by' indicates putting letters inside.
'male' becomes 'he'.
'soldiers' becomes 're' (Royal Engineers).
'he'+'re'='here'
'tin' enclosing 'here' is 'THEREIN'.
(Other definitions for therein that I've seen before include "Neither (anag) - into that" , "Inside that" , "in that respect" , "enclosed by that place?" .)
