Edgar Lee Masters
Knowlt Hoheimer (1916)

I was the first fruits of the battle of Missionary Ridge.
When I felt the bullet enter my heart
I wished I had staid at home and gone to jail
For stealing the hogs of Curl Trenary,
Instead of running away and joining the army.
Rather a thousand times the country jail
Than to lie under this marble figure with wings,
And this granite pedestal
Bearing the words, ”Pro Patria.”
What do they mean, anyway?
