Success is counted sweetest
By those who ne'er succeed.
To comprehend a nectar
Requires sorest need.

Not one of all the purple Host
Who took the Flag today
Can tell the definition
So clear of Victory

As he defeated--dying--
On whose forbidden ear
The distant strains of triumph
Burst agonized and clear!

Emily Dickinson
