Well, it may be cited that way but is 100% incorrect. Battery C was graveyard hill. That is where Price and his bunch attacked. Fagan and his brigade, including Hawthorne's regiment attacked Battery D farther to the south, so if it is stated that way then it was an incorrect statement made. Graveyard Hill, aka Battery C was taken by Price's force for a short while, as Fagan's brigade was attacking Battery D.
