On 27 July 1900, Kaiser Wilhelm II (centre, on the dais) delivered a speech to German troops sailing to suppress the Boxer Uprising. The speech has become notorious for a passage which the German foreign ministry tried to suppress in official versions subsequently circulated:
Should you encounter the enemy, he will be defeated! No quarter will be given! Prisoners will not be taken! Whoever falls into your hands is forfeited. Just as a thousand years ago the Huns under their King Attila made a name for themselves, one that even today makes them seem mighty in history and legend, may the name German be affirmed by you in such a way in China that no Chinese will ever again dare to look cross-eyed at a German.
