I am making a poor start on this one. Can someone give me a bit of a push please. 1 across would be a good start. Two gunners face artillery having lost unfortunate vital supply vessel (12, 2 words). It has to have a letter or word removed from the clue before solving. Sounds odd, but that is the way this puzzle will work.
All I have is the 8th or the 5th letter is an R, as some of the clues have to be entered in reverse.
