 The attack at Sinsinawa Mound , compounded by other incidents around the region , helped contribute to the fear gripping the settlers . The people of Platteville , in present @-@ day Wisconsin , contemplated fleeing to Galena , about 25 miles ( 40 km ) south , as a direct result of the Sinsinawa Mound raid . Colonel Dodge dispatched one of his men , Frederick Hollman , to Platteville to reassure its nervous residents . However , by the time Hollman arrived the settlers had already been informed that the local Native American Ho @-@ Chunk tribesmen were friendly . This and the subsequent delivery of promised supplies from Galena further placated Platteville 's residents , and the threatened exodus was called off .
