Ya I can see how it looks that way, but the guy is smart enough to have backed off at the first hint of her being uncomfortable or hesitant. He had soooo much to risk, I can't see him putting his neck out by forcing a girl against her will, even subtly. If he made a pass and she rejected it, he would have moved on. He is unlikely to have risked his career and marriage for anything other than a sure thing. I imagine he would also have gone to amazing lengths to try and cover his tracks and be discrete - although he obviously failed miserably at that!!!!
My guess remains that she was keen on banging the General, a willing participant. Either for fun and later bragging rights, or because she legitimately fell for him. Maybe she even had dreams of one day separating him from his wife. Who knows. Well, we all will, once the court martial transcripts are released!!
