While still encamped at the lower landing, some three or four days after the events last recounted, Mr. Joseph Meek, an old frontiersman and guide for emigrant trains through the mountains, came down from the Dalles, on his way to Vancouver, and stopped at my camp to inquire if an Indian named Spencer and his family had passed down to Vancouver since my arrival at the Cascades. Spencer, the head of the family, was a very influential, peaceable Chinook chief, whom Colonel Wright had taken with him from Fort Vancouver as an interpreter and mediator with the Spokanes and other hostile tribes, against which his campaign was directed. He was a good, reliable Indian, and on leaving Vancouver to join Colonel Wright, took his family along, to remain with relatives and friends at Fort Dalles until the return of the expedition. When Wright was compelled to retrace his steps on account of the capture of the Cascades, this family for some reason known only to Spencer, was started by him down the river to their home at Vancouver.
Meek, on seeing the family leave the Dalles, had some misgivings as to their safe arrival at their destination, because of the excited condition of the people about the Cascades; but Spencer seemed to think that his own peaceable and friendly reputation, which was widespread, would protect them; so he parted from his wife and children with little apprehension as to their safety. In reply to Meek's question, I stated that I had not seen Spencer's family, when he remarked, "Well, I fear that they are gone up," a phrase used in that country in early days to mean that they had been killed. I questioned him closely, to elicit further information, but no more could be obtained; for Meek, either through ignorance or the usual taciturnity of his class, did not explain more fully, and when the steamer that had brought the reinforcement started down the river, he took passage for Vancouver, to learn definitely if the Indian family had reached that point. I at once sent to the upper landing, distant about six miles, to make inquiry in regard to the matter, and in a little time my messenger returned with the information that the family had reached that place the day before, and finding that we had driven the hostiles off, continued their journey on foot toward my camp, from which point they expected to go by steamer down the river to Vancouver.
Their non-arrival aroused in me suspicions of foul play, so with all the men I could spare, and accompanied by Lieutenant William T. Welcker, of the Ordnance Corps—a warm and intimate friend—I went in search of the family, deploying the men as skirmishers across the valley, and marching them through the heavy forest where the ground was covered with fallen timber and dense underbrush, in order that no point might escape our attention. The search was continued between the base of the mountain and the river without finding any sign of Spencer's family, until about 3 o'clock in the afternoon, when we discovered them between the upper and lower landing, in a small open space about a mile from the road, all dead—strangled to death with bits of rope. The party consisted of the mother, two youths, three girls, and a baby. They had all been killed by white men, who had probably met the innocent creatures somewhere near the blockhouse, driven them from the road into the timber, where the cruel murders were committed without provocation, and for no other purpose than the gratification of the inordinate hatred of the Indian that has often existed on the frontier, and which on more than one occasion has failed to distinguish friend from foe. The bodies lay in a semicircle, and the bits of rope with which the poor wretches had been strangled to death were still around their necks. Each piece of rope—the unwound strand of a heavier piece—was about two feet long, and encircled the neck of its victim with a single knot, that must have been drawn tight by the murderers pulling at the ends. As there had not been quite enough rope to answer for all, the babe was strangled by means of a red silk handkerchief, taken, doubtless, from the neck of its mother. It was a distressing sight. A most cruel outrage had been committed upon unarmed people—our friends and allies—in a spirit of aimless revenge. The perpetrators were citizens living near the middle block-house, whose wives and children had been killed a few days before by the hostiles, but who well knew that these unoffending creatures had had nothing to do with those murders.
In my experience I have been obliged to look upon many cruel scenes in connection with Indian warfare on the Plains since that day, but the effect of this dastardly and revolting crime has never been effaced from my memory. Greater and more atrocious massacres have been committed often by Indians; their savage nature modifies one's ideas, however, as to the inhumanity of their acts, but when such wholesale murder as this is done by whites, and the victims not only innocent, but helpless, no defense can be made for those who perpetrated the crime, if they claim to be civilized beings. It is true the people at the Cascades had suffered much, and that their wives and children had been murdered before their eyes, but to wreak vengeance on Spencer's unoffending family, who had walked into their settlement under the protection of a friendly alliance, was an unparalleled outrage which nothing can justify or extenuate. With as little delay as possible after the horrible discovery, I returned to camp, had boxes made, and next day buried the bodies of these hapless victims of misdirected vengeance.
The summary punishment inflicted on the nine Indians, in their trial and execution, had a most salutary effect on the confederation, and was the entering wedge to its disintegration; and though Colonel Wright's campaign continued during the summer and into the early winter, the subjugation of the allied bands became a comparatively easy matter after the lesson taught the renegades who were captured at the Cascades. My detachment did not accompany Colonel Wright, but remained for some time at the Cascades, and while still there General Wool came up from San Francisco to take a look into the condition of things. From his conversation with me in reference to the affair at the Cascades, I gathered that he was greatly pleased at the service I had performed, and I afterward found that his report of my conduct had so favorably impressed General Scott that that distinguished officer complimented me from the headquarters of the army in general orders.
