Thetruth about the events surrounding the death of the highest ranking officer to be killed in the Afghanistan conflict has been revealed in a new book.

Lieutenant Colonel Rupert Thorneloe was killed in action in July 2009 while commanding the 1st Battalion Welsh Guards in Helmand Province.

Now, a new book brings to light the concerns Lt Col Thorneloe had about the safety of his battalion before his death.

The book, by Toby Harnden of the Daily Telegraph, reveals Lt Col Thorneloe was getting increasingly frustrated by the lack of men and equipment he had for the battalions tasks.

He told one of his officers that he believed Operation Panthers Claw was flawed.
