 The Sinsinawa Mound raid occurred on June 29 , 1832 , near the Sinsinawa mining settlement in Michigan Territory ( present @-@ day Grant County , Wisconsin in the United States ) . This incident , part of the Black Hawk War , resulted in the deaths of two men ; a third man survived by seeking cover in a nearby blockhouse . In the aftermath of the raid , Captain James W. Stephenson set out to pursue the attackers — a straggling band of Sauk Native Americans — but lost their trail at the Mississippi River . The attack occurred in the same week as other skirmishes and raids , and as a result helped contribute to the growing fear in the region . The raid caused the residents of nearby Platteville to consider fleeing their settlement .
