9 across. The only answer that I can find, that might fit the sense of the clue is 'redoubt', but that doesn't fit your G nor your number of letters. What do you think of my suggestion?
Thank you Danny and Bookbinder. 9 across is only 6 letters so as you say redoubt which sounds good would not fit. My G comes from Bad after seal is terminated (4.3) and I have put Gone off.
