My triumph lasted till the drums

My Triumph lasted till the Drums
Had left the Dead alone
And then I dropped my Victory
And chastened stole along
To where the finished Faces
Conclusion turned on me
And then I hated Glory
And wished myself were They.

What is to be is best descried
When it has also been -
Could Prospect taste of Retrospect
The Tyrannies of Men
Were Tenderer, diviner
The Transitive toward -
A Bayonet's contrition
Is nothing to the Dead -
