Isandhlwana. 22nd January, 1879.
1,300 Brits died, probably a lot more on The Boks side!
And all this on the day before Michael Caine walked his horse across a stream for another bundle at Rorkes Drift. Jack Hawkins was getting ready to shriek at everyone and the cook was starting to boil up the soup, before being told to put out the fires with it.
1969 - pretty much the same thing happened at Twickenham, but the Brits won then...
