Mike and Juno I fully agree with your views concerning the Victorian painting. My view are, to paraphrase the Duke Of Wellington, the history of a battle can be as futile as that of a history of a ball: the memoirs only relate to the personal experiences of the individual and they would have no idea what was going to a few feet away. I think that the notion of brave Scots infantry grabbing stirrups of the horses of their countrymen to be carried to fight the French is unlikely given the numbers of highlanders who were reported dead in square: had they done this charge they would have been slaughtered by the lancers. Moreover it's likely that anyone foolish enough to try it would lose their grip or fallen over pretty quickly. The recent dig around the location of the British field dressing station showed that heavy fighting took place in the vicinity, intense fighting not before reported despite hundreds of tomes on the subject.
As to the dress I always love the Rousselot comment which basically says that if we today saw the Napoleonic army we'd certainly have a few surprises. Paul Dawson is producing some fine research which does contradict some commonly held "facts" about dress and some great discussions go on with other contemporary uniformologists such as Yves Martin . I think I ought to make it clear that correspond with them both and at the moment am nagging Paul to publish all his research about French heavy cavalry dress and equipment but I have no vested interest other than wanting to read the results of his research. Of course without being there we don't fully know.
Enough of my waffle.
Cheers,
