Needing another option besides frontal assaults, Curtis decided to search for a weak point elsewhere in the Rebel lines. His scouts found a local farmer named George Thoman, who was eager to help the Federals as the Confederates had absconded with his horse the previous night. Thoman showed Curtis a gulch, cut by Swan Creek, running up to a rise along Shelby's left flank. Curtis personally directed his headquarters escort and the 9th Wisconsin Battery through this gully. Meanwhile, Blunt continued to push Jennison and Ford up the rise across Brush Creek, making slow progress until the 9th Wisconsin opened fire upon the Confederate flank and rear. Encouraged, Blunt's men now poured over the ridge, but Shelby's men fought back stubbornly and a see-saw battle ensued in the open prairie. The Union army gradually gained the upper hand, slowly pushing Shelby's brigades back to the Wornall House.
