Wake not for the world-heard thunder,  
Nor the chimes that earthquakes toll;  
Stars may plot in heaven with planet,  
Lightning rive the rock of granite,  
Tempest tread the oakwood under,  
Fear not you for flesh or soul;  
Marching, fighting, victory past,  
Stretch your limbs in peace at last.  
 
Stir not for the soldier's drilling,  
Nor the fever nothing cures;  
Throb of drum and timbal's rattle  
Call but men alive to battle,  
And the fife with death-notes filling  
Screams for blood--but not for yours.  
Times enough you bled your best;  
Sleep on now, and take your rest.  
 
Sleep, my lad; the French have landed,  
London's burning, Windsor's down.  
Clasp your cloak of earth about you;  
We must man the ditch without you,  
March unled and fight short-handed,  
Charge to fall and swim to drown.  
Duty, friendship, bravery o'er,  
Sleep away, lad; wake no more.
Alfred Edward Housman
