Robert Laurence Binyon - The Test

Naked reality, and menace near
As fire to scorching flesh, shall not affright
The spirit that sees, with danger--sharpened sight,
What it must save or die for; not the mere
Name, but the thing, now doubly, trebly dear,
Freedom; the breath those hands would choke; the light
They would put out; the clean air they would blight,
Making earth rank with hate, and greed, and fear.

Now no man's loss is private: all share all.
Oh, each of us a soldier stands to--day,
Put to the proof and summoned to the call;
One will, one faith, one peril. Hearts, be high,
Most in the hour that's darkest! Come what may,
The soul in us is found, and shall not die.

Robert Laurence Binyon
