When the Indians attacked the people at the Cascades on the 26th, word was sent to Colonel Wright, who had already got out from the Dalles a few miles on his expedition to the Spokane country. He immediately turned his column back, and soon after I had landed and communicated with the beleaguered block-house the advance of his command arrived under Lieutenant-Colonel Edward J. Steptoe. I reported to Steptoe, and related what had occurred during the past thirty-six hours, gave him a description of the festivities that were going on at the lower Cascades, and also communicated the intelligence that the Yakimas had been joined by the Cascade Indians when the place was first attacked. I also told him it was my belief that when he pushed down the main shore the latter tribe without doubt would cross over to the island we had just left, while the former would take to the mountains. Steptoe coincided with me in this opinion, and informing me that Lieutenant Alexander Piper would join my detachment with a mountain’ howitzer, directed me to convey the command to the island and gobble up all who came over to it.
Lieutenant Piper and I landed on the island with the first boatload, and after disembarking the howitzer we fired two or three shots to let the Indians know we had artillery with us, then advanced down the island with the whole of my command, which had arrived in the mean time; all of the men were deployed as skirmishers except a small detachment to operate the howitzer. Near the lower end of the island we met, as I had anticipated, the entire body of Cascade Indianmen, women, and children—whose homes were in the vicinity of the Cascades. They were very much frightened and demoralized at the turn events had taken, for the Yakimas at the approach of Steptoe had abandoned them, as predicted, and fled to the mountians. The chief and head-men said they had had nothing to do with the capture of the Cascades,
