On April 5, 1832, the British Band entered Illinois once again. Numbering about 500 warriors and 600 non-combatants, they crossed near the mouth of the Iowa River over to Yellow Banks (present-day Oquawka, Illinois), and then headed north. Black Hawk's intentions upon reentering Illinois are not entirely clear, since reports from both white and Indian sources are conflicting. Some said that the British Band intended to reoccupy Saukenuk, while others said that the destination was Prophetstown. According to historian Kerry Trask, "even Black Hawk may not have been sure where they were going and what they intended to do".
