After Atkinson's arrival at Rock Island on April 12, 1832, he, Keokuk, and Meskwaki chief Wapello sent emissaries to the British Band, which was now ascending the Rock River. Black Hawk rejected the messages advising him to turn back. Colonel Zachary Taylor, a regular army officer who served under Atkinson, later stated that Atkinson should have made an attempt to stop the British Band by force. Some historians have agreed, arguing that Atkinson could have prevented the outbreak of war with more decisive action or astute diplomacy. Cecil Eby charged that "Atkinson was a paper general, unwilling to proceed until all risk had been eliminated". Kerry Trask, however, argued that Atkinson was correct in believing that he did not yet have enough troops to stop the British Band. According to Patrick Jung, leaders on both sides had little chance of avoiding bloodshed at this point, because the militiamen and some of Black Hawk's warriors were spoiling for a fight.
