Most renowned was the Battle of St. Croix Falls in the late 1770s when Waub-O-Jeeg was about 30 years old. The Fox and Sioux were encroaching on Chippewa hunting territory in the St. Croix valley. It was early summer when Waub-O-Jeeg mustered his warriors by sending wampum and tobacco to villages along the south shore of Lake Superior as far as L'Ance and Sault Ste. Marie and south to the Wisconsin River. Three hundred men gathered at La Pointe on Cheqamegon Bay to make the trip of two hundred fifty miles to the falls of the St. Croix. Sixty more Chippewas from Big Sand Lake west of Lake Superior were to meet them at the Snake River outlet on the St. Croix. Waub-O-Jeeg's party proceeded in birch bark canoes from Chequanemegon Bay up the Bad River to connecting portages to the Namekagon River that flowed west into the St. Croix. They proceeded cautiously in their canoes down the St. Croix with scouts going ahead to watch for the enemy. The Sandy Lake contingent did not appear at the Snake River outlet but Waub-O-Jeeg continued on. It took seven days to reach the upper end of the St. Croix Falls portage. According to Schoolcraft who canoed up this river in 1832, admiring its beauty along the way, the portage around the falls and rapids was about four hundred yards.
