There is a bitter river
Flowing through the South.
Too long has the taste of its water
Been in my mouth.
There is a bitter river
Dark with filth and mud.
Too long has its evil poison
Poisoned my blood.
I've drunk of the bitter river
And its gall coats the red of my tongue,
Mixed with the blood of the lynched boys
From its iron bridge hung,
Mixed with the hopes that are drowned there
In the snake-like hiss of its stream
Where I drank of the bitter river
Hughes goes into deeper detail of the young boys' wrongful deaths–Charlie Lang and Ernest Green died beneath the Shubuta Bridge in Mississippi. This bridge became famously known as the “Hanging Bridge”.
