The engineers in that place (5)
I believe the answer is:
there
'in that place' is the definition.
(over there)
'the engineers' is the wordplay.
'engineers' becomes 're' (abbreviation for Royal Engineers).
'the'+'re'='THERE'
(Other definitions for there that I've seen before include "in that case" , "In that respect" , "Yonder" , "It's said to comfort" , "Word of comfort" .)
