On June 16 , Alexander Posey and Milton Alexander were elected by the brigades they helped organize to command , respectively , the First and Second Illinois Militias . In the aftermath of the Second Battle of Kellogg ' s Grove , Alexander was ordered by Atkinson to search the banks below the Galena in order to prevent a possible retreat of Black Hawk ' s band across the Mississippi River . However , after a fruitless search , Alexander continued along the eastern side of Rock River with Colonel Jacob Fry until reaching a Winnebago village on Whitewater , a tributary of Rock River . Rejoining General Atkinson at Lake Koshkonong on June 3 , they were joined by General Posey and Colonel Henry Dodge the following day . That evening , Atkinson received a report from scouts that they had located the main trail three miles upriver and the main force set out to investigate early the next morning . With Alexander and Dodge searching the west bank of Rock River , they traveled 15 miles before turning back finding no trace of Black Hawk ' s band . Eventually running low on provisions , he was sent to get supplies from Fort Winnebago with General Henry and Colonel Dodge . While there , they received news that Black Hawk had been sighted in the area and it was decided that Dodge and Henry would pursue Black Hawk while Alexander would return to the main force with the supplies . At the Battle of Bad Axe , he and Posey led the right flank and was part of the final charge with Dodge , Henry and Posey which ended the battle . His brigade suffered no casualties with the exception of one soldier who was wounded . Later years .
