Today was my first chance to see Daniel Maclise’s great Waterloo Cartoon, which has been restored over the course of the last year, was shown at the Royal Armouries during the summer, and now goes on display in the RA’s Large Weston Room for the autumn, as our way of marking the bicentenary of the Battle.   It’s quite an amazing work, on a vast scale, ostensibly celebratory as it shows the moment when Wellington greets Field Marshal von Blücher outside what had been Napoleon’s headquarters, but also full of the travails of war, the fallen soldiers.   In all, a celebration of grim heroism.
