Sigel formed his line of battle within a half mile of the enemy's position, distributed his artillery along it, then ordered an advance, and opened the battle with a fire from his guns, which was promptly responded to by the enemy's pieces. The distance was so close that the Union guns could fire canister and shell very effectively; but the enemy, perceiving that Sigel had no cavalry, sent out their numerous mounted force on a flank movement, which soon compelled the retirement of the line across the creek, where the battle was renewed and maintained for two hours, during which time the enemy suffered some loss from the artillery fire. 140 Again the enemy made a flank movement with their cavalry, reaching this time back toward the baggage-train, to which Sigel retreated. The Union men broke up the cavalry formation, and Sigel followed this with a charge which scattered his enemies and enabled him to continue his retreat unmolested across the prairie in full sight of his foes. Sigel could also see the rallied cavalry making a wide circuit over the prairie to gain the hights of Spring River and cut off his retreat Gen. Rains, who led this movement, succeeded in reaching the road at Spring River, but in coming up Sigel at once attacked with his artillery, and after a brisk little engagement of half an hour drove the enemy out of the woods, and marched on to Carthage, which he reached about 5 o'clock, and there prepared to give a short rest to his men, who were worn out by 18 miles of marching under a hot sun and almost continual fighting and manuvering. The Secessionists renewed their attack, but were again driven off by the infantry and artillery, and the march was resumed. Again Gens. Slack, Parsons, and Clark pushed their men forward on the Union flank, while Rains renewed his attack, and again they were all repulsed, largely by the skillful handling of the artillery. As darkness came on the Secessionists disappeared, but Sigel moved on to Sarcoxie, 12 miles distant, and went into camp. 141 Gov. Jackson's forces camped in and around Carthage, and the next day marched to Neosho, where they met Gen. Ben McCulloch coming up from Arkansas with a force of Arkansans and Texans and also 1,700 of the State Guards, which Gen. Price had brought forward. In the fighting the Union side had lost 13 killed and 21 wounded. The Confederates report 74 killed and wounded in the four divisions under the command of Gov. Jackson.
