The Boer War.
Biggest invasion since Boer War: 20,000 England fans arrive in Bloemfontein
Sigh. [Dammit: they've changed it since I commented. I should always, always, always do screenshots on these things.]
It occurred to me among all this martial breast-beating that there is another association that comes to mind when adding the words Germany + England + Football + War: the 'Christmas Truce' from 1914, when, for a brief period soldiers on both sides of the lines put down their arms and shared some kind words, alcohol and, legend has it, an impromptu football match or two.
The football bit isn't in this excerpt from Oh! What a Lovely War (1969), but it's still wonderful.
I know it's too early for Christmas.
And certainly -- in football terms -- for a truce.
(PS: I know that some of the soldiers in that excerpt are Scottish rather than English. But not all of them.)
