of mountains, in order to disabuse them of the idea that they were
sufficiently strong to cope with the power of the Government. He
therefore at once set about the work of organizing and equipping his
troops for a start in the early spring against the hostile Indians,
intending to make the objective point of his expedition the heart of
the Spokane country on the Upper Columbia River, as the head and
front of the confederation was represented in the person of old
Cammiackan, chief of the Spokanes.

The regiment moved from Fort Vancouver by boat, March 25, 1856, and
landed at the small town called the Dalles, below the mouth of the
Des Chutes River at the eastern base of the Cascade Range, and just
above where the Columbia River enters those mountains. This
rendezvous was to be the immediate point of departure, and all the
troops composing the expedition were concentrated there.

On the morning of March 26 the movement began, but the column had
only reached Five Mile Creek when the Yakimas, joined by many young
warriors-free lances from other tribes, made a sudden and unexpected
attack at the Cascades of the Columbia, midway between Vancouver and
the Dalles, killed several citizens, women and children, and took
possession of the Portage by besieging the settlers in their cabins
at the Upper Cascades, and those who sought shelter at the Middle
Cascades in the old military block-house, which had been built some
years before as a place of refuge under just such circumstances.
These points held out, and were not captured, but the landing at the
Lower Cascades fell completely into the hands of the savages.
Straggling settlers from the Lower Cascades made their way down to
Fort Vancouver, distant about thirty-six miles, which they reached
that night; and communicated the condition of affairs. As the
necessity for early relief to the settlers and the re-establishment
of communication with the Dalles were apparent, all the force that
could be spared was ordered out, and in consequence I immediately
received directions to go with my detachment of dragoons, numbering
about forty effective men, to the relief of the middle blockhouse,
which really meant to retake the Cascades. I got ready at once, and
believing that a piece of artillery would be of service to me, asked
for one, but as there proved to be no guns at the post, I should have
been obliged to proceed without one had it no
