Marmaduke's division was attacked by three of Pleasonton's brigades starting at 8:00 on the morning of the 23rd; the Confederates initially managed to hold their own. One of the Union brigade commanders, Brig. Gen. Egbert B. Brown stalled his attack and was placed under arrest by Pleasonton for disobeying orders. Another of Pleasonton's brigade commanders, Col. Edward F. Winslow, was wounded and succeeded by Lt. Col. Frederick Benteen, who would later ride to fame at Little Bighorn. Despite these setbacks, Federal troopers gained the west bank by 11:00 and Marmaduke retired. As Brown's brigade (now led by Col. John F. Philips) forded the river, they came under heavy fire from Marmaduke's artillery. Once they had crossed, they charged Marmaduke across an open field; during this charge, Union troops from Missouri and Arkansas battled Confederates from these same two states. Marmaduke was forced back, rejoining Shelby and Fagan, and Blunt pounded the now-consolidated Confederate remnants with his own cannon.
