Using that technique shouldn’t be limited to scenes on a battlefield. In my novel, ‘The Long Road to Sunrise’, a girl from an Amazonian tribe is caught and raped by fierce warriors from another village. I didn’t sink to describing the rape in detail. That would have been gratuitous. Instead, I chose to describe just enough for the reader to appreciate the horror of the situation and left the rest to the imagination. Once again, it was a matter of balance. The way I chose to set about it was to describe in detail the run-up to the rape, highlighting the girl's fears and her sense of extreme horror. Then, at the moment of attack, I stopped and let the reader imagine what came next. I think it worked.
