During September-October 1939 throughout ten Allied countries, and upon the suggestion of FIDAC (Inter-allied Federation of Ex-Servicemen), the 25th anniversary of Laurence Binyon's "For the Fallen", was observed.
This is one of the most famous and enduring war poems, and it was written at an historic moment … just after the retreat from Mons and the victory of the Marne.
As to how it came to be written, Laurence Binyon, who celebrated his 70th anniversary on 10 August 1939, says: "I can't recall the exact date beyond that it was shortly after the retreat. I was set down, out of doors, on a cliff in Polzeath, Cornwall. The stanza "They Shall Grow Not Old" was written first and dictated the rhythmical movement of the whole poem."
His words cut so precisely to the heart, such a profound embrace of humanity, it leaves one numb.
I love the fact that i'm overwhelmed by your amazing poems 
This superlatively expresses a feeling all too rare these days, the prevailing wind now being to write off the death of heroes as a pure waste (which most of the deaths in WW1 may well have been, since all that war did, thanks to U.S. intervention, was to set the stage for WW2, but still, that does not negate the value of heroism when it does matter, as I hope all sane, rational souls will agree). The meter is somewhat rough, yet that gives it a sort of conversational tone which allows it to be old-school without being too staid or formal sounding. Very effective!
Mournful snd incantationary metre never fails to move me (depends how you read it I suppose). Why do people repeat the last line of verse four on ceremonial readings? As is often the case pomp detracts from poetic impact.
Very nicely written. Tremendous impact on emotions. Wording is point on. Flow is beautiful. Great job.
