In Great Britain, it’s called Remembrance Day. There will be two minutes of silence at 11:00 and wreaths of poppies will surround the Cenotaph. Around the world, the ceremonies may differ, but they go back to one day: On November 11, 1918, Germany formally surrendered, and thousands of exhausted, hungry, battle-haunted veterans returned home – if home was still there. Photos from that era reflect a mix of relief, jubilation, and the blank stares of shell shock. They also show how very young were the great fighting forces of the Great War, on all sides of the conflict.

A century after “the war to end all wars,” and after all the wars since that it failed to end, shouldn’t we be doing more than remembering? It’s a question songwriter Eric Bogle asks in “No Man’s Land.” Ultimately, he’s not asking young Willie McBride, or rather, his headstone, to answer his question. He’s asking us:

And I can't help but wonder now, Willie McBride,
Do all those who lie here know why they died?
Did you really believe them when they told you the cause?
Did you really believe them that this war would end wars?
Well, the suffering, the sorrow, the glory, the shame -
The killing, and dying - it was all done in vain,
For, Willie McBride, it all happened again
And again, and again, and again, and again.

This Veterans Day, listen to Bogle’s song, as sung by Celtic-American punk rock band Dropkick Murphys.
