Lot's more of this back at the page where I found it (written sometime before 1890):

MAGGIE PEER.
A TRUE TALE OF THE WAR.

The Bird of Peace has spread her wings
Again in our glorious sky;
But plaintive and sad is the song she sings,
So sad that many a sigh it brings,
And tears to many an eye.
She has gained the prize, but at fearful cost,
For she misses the true and the brave;
She mourns for the loved forever lost—
For the war-worn feet that forever crossed
The portal of the grave.
