Jemma Connor, 25, had been drinking in Newport city centre with friends when a street brawl broke out around 2.30 am on Sunday.
Video of the horror incident shows Jemma standing in the middle of two men in a bid to separate them as they fight.
But to her surprise, she catches one of their stray punches directly in the face.
The force of the blow sends her flying backwards and off her feet.
Her head bounces off the ground, before she immediately places her hands over the impact area.
She remains sprawled out still on the ground as the fight continues.
One man approaches her momentarily, attempting to help her back to her feet but is soon distracted by the ongoing fight and walks away.
The group soon makes their escape from the situation as quickly as they could.
Jemma said she isn’t sure if the police arrived while she and her friends were still in the area.
The following day she said she felt sick and had bruises on her face.
She said the attack left her feeling frightened and delirious after suffering bruising to her face.
