A second lot could come up from the rear, while those with whom the palefaces and Beaver Tail himself were associated advanced along the shore of the lake, and expected to reach the vicinity of the camp in that way.
The boys had never gazed upon a body of water anything like the size of that lake, though accustomed to the big Missouri River in flood-time, when it was miles from shore to shore. Once they had cruised down to the Mississippi in company with Roger’s father, Sandy Armstrong, who had built a big canoe and wanted to revisit the place where, as a lad, he had had a temporary home.
Seen in the sheen of the starlight, the lake looked as though it might be an ocean in itself, for no further shore was visible. Roger wondered if this was what the sea resembled, and if he and Dick would really be permitted to continue on with the explorers, cross the rocky range of mountains, and finally bring up on the golden strand of the Pacific Ocean.
But there was a glimmering light close by, which he surmised was a smoldering fire in the French traders’ camp. Carefully they continued to creep forward. It gave Roger a thrill to realize that he was in the company of savages such as his father and grandfather had fought in the years gone by; but who were now their best of friends. What wonderful stories he and Dick would have to tell should they live through all these manifold perils to return safely home, and resume their old places at the domestic fireside.
Both boys were secretly hoping that Lascelles and his compatriots would not be so foolhardy as to attempt to resist. Bad as these men were, the boys did not wish to see them butchered, as they undoubtedly would be should they fire on the Sioux, or even wound one of Beaver Tail’s warriors.
As for any stray Blackfeet who may have remained in camp while the main body was off somewhere, if they got in the way of the Sioux arrows or tomahawks that was their lookout; the boys could not be expected to include them in the scheme of general amnesty.
The attack was not to be started until certain signals announced that all the detachments had reached the positions assigned to them by the chief. When he heard the howl of a wolf given with a certain little twist at the finish, and then also caught the cry of the screech-owl, he would feel assured that nothing remained to be done but order a concerted assault.
Indians have always had a certain set plan for their surprises. No matter how slyly they crept up on blockhouse or camp or border fort, when a certain time arrived they felt it was absolutely necessary to break out in ferocious yells. No doubt this was done partly to give freedom to their pent-up feelings, and, at the same time, add to the alarm of those whom they were attacking.
Dick and Roger knew this fact. They had had some little experience themselves in connection with Indians. Besides this, they had heard innumerable stories from Grandfather David concerning those days along the Ohio, when the tribes from the Great Lakes to the southern border of Kentucky were all on the warpath, and seeking day and night to destroy the hardy pioneers.
This being the case, neither of the lads felt any surprise when there arose a series of the most dreadful yells. The warriors whom they accompanied added to the din with all their might, at the same time springing forward and running in the direction of the near by camp.
