then Maxey's division would take the halted train in the flank. As planned, Williams' Union force was blocked by Marmaduke and Cabell on April 18, and Maxey's division, composed of a brigade of Texans under Colonel Charles DeMorse and Walker's Native Americans, hit the flank of Williams' column. However, Maxey's initial assault was repulsed by the 1st Kansas (Colored). The next Confederate charge was more coordinated, with Marmaduke and Maxey attacking the Union force simultaneously. After a fight of about an hour, Maxey's men were again forced to retreat, but the Union soldiers began to run low on ammunition. A third Confederate charge broke the flank of the Union position, and the 1st Kansas (Colored) abandoned its position. The 18th Iowa attempted to form a second line but was quickly driven off by the Confederate assault. The African-American soldiers of the 1st Kansas (Colored) were "showed [..] no quarter". Many of the members of the Kansas regiment who fell into Confederate hands were killed and mutilated; some observers reported that Walker's Choctaws took scalps from dead Union soldiers. Walker would later write: Williams' Union column lost 301 men. The 1st Kansas (Colored) lost 182 men out of 438 men who had participated in the battle. 117 of the 182 losses in the Kansas regiment were killed, which was an unusually high killed-to-wounded ratio. In comparison, the Confederates lost 114 men. The Confederates also captured four cannons and 175 wagons. Within the wagons were 5,000 bushels of corn and non-military items such as furniture and civilian clothing. Aftermath and preservation A week later, on April 25, another Union wagon train was captured at the Battle of Marks' Mills. With his forces' lack of supplies, especially food, becoming increasingly problematic, Steele decided to give up on his campaign and withdraw from Camden. Some Confederate forces that had been shifted south to fight Banks were returned to Arkansas. The now-strengthened Confederate force pursued Steele and caught up with the Union soldiers while they were trying to cross the Saline River. On April 30, the Confederates attacked Steele's position near the river in the Battle of Jenkins' Ferry. Steele's forces repulsed the Confederate attacks, allowing the Union soldiers to cross the river. Steele's retreat ended on May 2 when the Union forces reached Little Rock. Steele's force is estimated to have traveled around 275 miles throughout the entire campaign. The site of the battlefield
