 On June 29 , 1832 , what was probably a small band of Sauk attacked three men working in a cornfield at the Jones mining settlement near Sinsinawa Mound . The Sauk took up a position directly between the settlers and their weapons . Two of the men — James Boxley and John Thompson — were killed by the raiding party ; their badly mutilated bodies were later recovered . The third , an unidentified man , made a run for Jones blockhouse and survived the attack . The raiders were most likely a group of stragglers from the main body of the British Band , which was moving toward the Rock River with Chief Black Hawk .
