The Duke of Wellington’s international army included — among others — British, Dutch, Belgian and German troops. Waterloo was thus, as the D-Day veteran and former Chief of the General Staff Lord Bramall put it, “the first Nato operation”. It was primarily, however, an Anglo-German effort, and no formation epitomised that achievement more than the King’s German Legion, made up largely of Germans fighting in British uniforms as part of the regular British army. The defence of the key farmhouse of La Haye Sainte at the centre of the allied line by the Second Light Battalion of the Legion under Major Baring held up Napoleon for long enough to allow the Prussians to arrive.
