I read somewhere in one of the subject that someone played a dutch-belgian army which was mainly "poor" and "conscript" .While some units where undoubtly "green", many soldier's had fought for France in 1813-1814 and were far from being "newbies" . 2 corps commander ( Chassé and Collaert) and all 3 cavalry commanders had fought on the french side for years and , contrary to the legend, did not negociate with the french ennemy . Dutch-Belgian units fought with courage . You should remember that at Quatre-Bras, it was the Dutch-Belgians that did stop Ney untill enough reinforcements could help . Nassau was under Dutch-Belgian command . The 5th dutch militia regiment lost 50% of it's strengh and did fight again at Waterloo . The 7th line unit stood it's ground and was publicly complimented by Wellington . The 8th belgian Husssars lost up to 65% of it's original strengh and still continued to fight . General Trip, commended by Wellignton, was in charge of the dutch-belgian heavy brigade that counter charged the french cavalry . 4th Dutch light Dragoons 38 % loss and fought all day long, 5th Belgian light dragoons 36 % loss at Waterloo . heavily engaged at Quatre Bras and , after having lost 171 men there, where engaged at Waterloo and lost another 157 men . it is that unit that the french tried to entice coming to join them .
I do not say that the Dutch-Belgian should all be superior veteran , but that they should not be underestimated . There will be conscripts, poor units but also some drileld average .
By the way, one forgotten historical fact is that if the british guard brigade did face the french middle guard ( not the old guard that did never charge the british contrary to the legend) it is Detmer's brigade ( mostly militia ) that did charge the 1/3 Grenadier à Pied with shako on the bayonnets and they did repulse them
