Progressing to draw no return (6)
I believe the answer is:
onward
'progressing' is the definition.
(thesaurus)
'draw no return' is the wordplay.
'return' says the letters should be written in reverse.
'draw'+'no'='drawno'
'drawno' backwards is 'ONWARD'.
'to' is the link.
(Other definitions for onward that I've seen before include "Advance like Christian soldiers" , "Direction to be taken by Christian soldiers?" , "Forward in time" , "Forward, like Christian soldiers" , "Going on, advancing" .)
