"April 29, the date chosen for Prince William's wedding to Kate Middleton, was chosen because it is the anniversary of the death of St Catherine of Siena. However the day has also seen some far less auspicious events through history."
Hitlers wedding (fair enough Telegraph)
German forces in Italy surrendered (errr ... actually sounds good)
Dachau was liberated (also sounds good)
Cardinal Richelieu of France became worlds first prime minister. Telegraph points out this led to widespread reforms and united France (okay so on one side a good thing but on the other it helped France so we can call this a tie).
The Easter Rising ends (good for the Irish in that it leads to our Republic, good for the Brits as they kicked our ass and had yet to mess up and unite the country against them).
So the only really less auspicious moment could be the Hitler thing. And since that did end in suicide in 24 hours, it is hardly that tremendously bad. Did someone notice the Hitler connection, write the headline and tried to justify the article with random historical events?
