Hi Andrew,

afaik there has been no depiction of the actual fighting. This is not surprising, as the fight was lost by the Allies (and so no Dutch or British painter would like to record such a subject), but it was also the end of Napoleon, and not a resounding victory that sent shockwaves of hope through France at the time, so not many French painters would feel a need to furnish a painting of the subject.
The Archives at Bergen, the Markiezenhof, also report to have no knowledge of a painting or sketch on the subject in existence.

Hope you can find subsitute material,
cheers,
Bas
