I have had several of these e-mails over the past couple of years. Some people seem to find them funny, but I have serious misgivings about them. Someone is trying to propogate the idea that "Englishness" (whatever that might mean) is under threat and needs protection from all the usual suspects. I received this particular piece of doggerel some weeks back and just to clear up a few misgivings, I actually annotated it and sent it back.

I wonder how many readers even recognised the title and have read the short story (by DH Lawrence) to which it alludes. That was anything but a piece of breast beating psuedo patriotism. Shaw, of course was Irish. Agincourt, whilst indeed a famous victory, was actually fought so that a beaten army could run away and hop on the Calais Dover Ferry after an unsuccessful hooligan season. (England's excuse for being there was so piffling that even Shakespeare took the piss out of it at the start of Henry V).
No one wishes to decry the heroism of English soldiers at Arnhem, but we should also mention the very brave Scots, Welsh, Irish, Canadians and Poles.

"Europe is miles away over the sea." It is also close enough for a person of exceptional fitness to swim.

"We are proud of our heritage the red, white and blue." Can anyone tell me where I might find the blue in the flag of St.George?

In short, I reckon this piece of doggerel has little value as either history or poetry.
