D. R. Atchison, former Senator from Missouri, President of the United States Senate, and of much notoriety during the Kansas and Nebraska troubles, took command of this force and attacked Col. Scott, compelling rapid retreat. Atchison reported to Price the usual story about the small number under his command and the large force of the Yankees routed, but this does not harmonize with his praises to Cols. Sanders, Patten, Childs, Cundliff, Wilfley, and Maj. Gause, each of whom he says handled his "regiment" with great gallantry. Col. Smith met Col. Scott in his retreat, learned from him the overwhelming force in front, and retreated with him, so that portion of the relief came to naught. Gen. Sturgis moved forward from Mexico with about 4,000 men and reached the Missouri River, but finding no means for crossing, and surveying the host that was gathered around the city, retired with such haste as to leave his tents and camp equipage. Gen. Price proceeded with astonishing deliberation, when we consider that he must have known that Fremont had something over 20,000 men within striking distance. Retreat was still open for Col. Mulligan, as he had two steamboats at his command, but he felt that his orders obliged him to remain in Lexington for the protection of much public property which had been gathered there, and that as his situation was known to Gen. Fremont, relief would be speedily sent to him. 210 In the meantime, every hour had swelled Gen. Price's forces. Some of the Secession writers have claimed that there were actually as many as 38,000 men gathered in his camps. Of course, a large proportion of his force was useless unless to help beat off a relieving column, because, owing to the small extent of the position occupied by Col. Mulligan, only a limited number of men could be employed against it, and 10,000 were as effective as 100,000. A very large portion of Gen. Price's forces were men who flocked to his camp as to a picnic or a barbecue, because something was going on, and they fell away from him again when he began a backward movement, as rapidly as they came.
