Would seem to make sense, contempory accounts would reflect it purely from military POV, and generally dont include moods or feeling of the participants, later one publicly is going to being able to a relate a fuller account with the benefit of reflection and describe it fuller then one would in a report.
To discount it, where are the accounts of widespread ill feeling, insults, or descriptions of hatred.........if it was widespread its hard to imagine its not mentioned, and mentioned frequently
Again the only way one can know what was in someone's mind is by what they tell you, as they are the only one privy to their thoughts, one can accept it, or discount it........but discounting it doesn't give anyone any insight into what was in his mind or thoughts at all for giving the order to change stance, he himself gave his reasoning it was a salute. Does anyone have an earlier account of Chamberlain where he states he felt his men were so full of hate and spite he felt it necessary as to try help prevent insults, as was previously claimed?
