In his letter of the 11th July 1815, John Marshall provided a highly detailed description of the Battle of Waterloo  and the part played by the Light Cavalry Brigade under by Sir Hussey Vivian: 'It was now near eight in the evening and still the battle raged with redoubled fury, and still was much to be done and but little time to do it in for night was fast approaching. Therefore no time was to be lost. Our brigade was then formed into three lines, each regiment composing its own line, which was; the 10th; 18th; and a regiment of German Legion Hussars, my own regiment forming the first line. The General, he said "You know what you are going to do, and you also know what is expected of you. And I am well assured it will be done. I therefore shall say no more, only wish you success." And with that he gave us the order to advance.' The file  contains details of  John Marshall’s military service, and it should be noted that the entire contents are available within the on-line archive.
