A black man, his overseer byt the name of Artayou Carrier, did that to him.
Peter had gone crazy, stole a gun and threatened to shoot his own wife. He has no memory of his rampge or whipping that followed. Many of the cruelest overseers were black men , sometimes even free black men, given power over others. That was the case here.
When the plantation owner saw peters injuries he fired the overseer and let peter rest for a few months. Even among southern plantation owners this whipping was excessive and horrified them.
When peter eventually eacaped north he injuries were photographed for propoganda purposes. Writers half embelished his story, leaving out the part where he was a rampaging criminal, and rewrote historynsaying "all slaves were treated as bad as peter here".
