Analysis of Shiloh - A Requiem

Skimming lightly, wheeling still,
The swallows fly low
Over the field in clouded days,
The forest-field of Shiloh --
Over the field where April rain
Solaced the parched one stretched in pain
Through the pause of night
That followed the Sunday fight
Around the church of Shiloh--
The church so lone, the log-built one,
That echoed to many a parting groan
And natural prayer
Of dying foemen mingled there --
Foemen at morn, but friends at eve --
Fame or country least their care:
(What like a bullet can undeceive!)
But now they lie low,
While over them the swallows skim,
And all is hushed at Shiloh.
