e 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, with the murder of men at the upper landing, nor with the
massacre of men, women, and children near the block-house, and put
all the blame on the Yakimas and their allies. I did not believe
this, however, and to test the truth of their statement formed them
all in line with their muskets in hand. Going up to the first man on
the right I accused him of having engaged in the massacre, but was
met by a vigorous denial. Putting my forefinger into the muzzle of
his gun, I found unmistakable signs of its having been recently
discharged. My finger was black with the stains of burnt powder, and
holding it up to the Indian, he had nothing more to say in the face
of such positive evidence of his guilt. A further examination proved
that all the guns were in the same condition. Their arms were at
once taken possession of, and leaving a small, force to look after
the women and children and the very old men, so that there could be
no possibility of escape, I arrested thirteen of the principal
miscreants, crossed the river to the lower landing, and placed them
in charge of a strong guard.

Late in the evening the ste
