Hi radarman
Bets to give the clues - more people will be able to help.
4d last 4 letters mean "cut"; I didn't think first 3 were that close for "walk steadily"; def. "field"
6d 3 letter gear, church abbr., (French) boy upwards - def. "general" (who might need you)
11a I didn't like either. Def "edit", in the sense of "remove"
12a def "he values", then anagram
Not a good RT, I thought.
