This was almost as barren of adventure as the outward passage, though a savage attack by a handful of Blackfeet,--henceforward to be the bitter foes of Rocky Mountain traders and pioneers,--and the accidental wounding of Lewis by one of his party, were unpleasant interruptions in the monotony of the steady marching, paddling, and hunting. It is remarkable that, throughout the western expansion of the United States after the Revolution, our northern pioneers from Pennsylvania to Oregon should have felt--in many cases bitterly--the tricky, insulting hatred of British traders and their Indian allies. As Washington in 1790 laid at the door of British instigators the cause of the long war ended by Wayne at Fallen Timber, so, all the way across the continent our pioneers had to contend with the same despicable influence, and were driven by it to deeds which made them, in turn, equally despised by their northern rivals. "I was in hopes," wrote an early pioneer, "that the British Indian traders had some bounds to their rapacity ... that they were completely saturated with our blood. But it appears not to have been the case. Like a greedy wolf, not satisfied with the flesh, they quarrelled over the bones.... Alarmed at the individual enterprise of our people ... they furnished [the Indians] with ... the instruments of death and a passport [horses] to our bosom." Even at the very beginning these first Americans on the Columbia and the Bitter Root range had a taste of Indian hatred from both the Blackfeet and the Crows. On the way back to the Mandan villages the explorers had an experience which was by no means insignificant. As they were dropping down the upper Missouri, one day two men came into view; they proved to be American hunters, Dickson and Hancock by name, from Illinois. They had been plundered by the fierce Sioux, and one of them had been wounded; it can be imagined how glad they were to fall in with a party large enough to ward off the insults of the Sioux. The hunters did remain with Lewis and Clark until the Mandan villages were reached, but no longer. Obtaining a fresh start, the two turned back toward the Rockies, and one of Lewis and Clark's own soldiers, Colter (later the Yellowstone pioneer), went back with them. These three led the van of all the pioneer host under whose feet the western half of the continent was soon to tremble. Holding the Sioux safely at bay during the passage down the Missouri, Lewis and Clark in September were once again on the straggling streets of the little village of St. Louis, then numbering perhaps a thousand inhabitants.
