The army commanded by the Duke of Wellington at Quatre-Bras and Waterloo included two infantry divisions and three cavalry brigades of the newly-unified Netherlands (or 'Dutch-Belgian') army.The part played by these troops in the two battles, under experienced officers many of whom had seen long service in Napoleon's campaigns, has often been unjustly dismissed by British commentators.The organisation, uniforms, and battle record of the Belgian units are explained here in detail by an experienced researcher in Continental archives, and illustrated by a specialist in the period, who actually lives at Waterloo.
