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

been obliged to proceed without one had it not been that the regular
steamer from San Francisco to Portland was lying at the Vancouver
dock unloading military supplies, and the commander, Captain Dall,
supplied me with the steamer's small iron cannon, mounted on a wooden
platform, which he used in firing salutes at different ports on the
arrival and departure of the vessel. Finding at the arsenal a supply
of solid shot that would fit the gun, I had it put upon the steamboat
Belle, employed to carry my command to the scene of operations, and
started up the Columbia River at 2 A.M. on the morning of the 27th.

bring up any volunteer assistance that in the mean time might have
been collected at Vancouver.

The Columbia River was very high at the time, and the water had
backed up into the slough about the foot of the Lower Cascades to
