On 14 November 1908, Dietrich Graf von Hülsen-Haeseler died of a heart attack while on a hunting trip in honor of the Kaiser. The hunting party was staying at Donaueschingen Castle in Donaueschingen, Baden; the Black Forest country estate of Prince Max von Fürstenberg. During a formal evening function, von Hülsen-Haeseler appeared dressed in the pink tutu and rose wreath of a ballerina, dancing for the Kaiser and his assembled guests.[1] The performance included pirouettes, jumps, capers and flirtatious kisses to the audience.[2] Apparently exhausted by his exertions, the general bowed, collapsed and was pronounced dead after hasty medical attention.[3][4] The circumstances were covered up by the officer corps so as not to further inflame public pressure over the homosexually themed Harden–Eulenburg affair. Ironically, it was von Hülsen-Haeseler who had organized the cover-up of that scandal.
