There is a word / Emily Dickinson

There is a word
Which bears a sword
Can pierce an armed man --
It hurls its barbed syllables
And is mute again --
But where it fellThe saved will tell
On patriotic day,
Some epauletted Brother
Gave his breath away.

Wherever runs the breathless sun --
Wherever roams the day --
There is its noiseless onset --
There is its victory!
Behold the keenest marksman!
The most accomplished shot!
Time's sublimest target
Is a soul "forgot!"
