The choice of routes by which you will enter California will be left to
your better knowledge and ampler means of getting accurate information.
We are assured that a southern route (called the Caravan route, by which
the wild horses are brought from that country into New Mexico) is
practicable, and it is suggested as not improbable that it can be passed
over in the winter months, or at least late in autumn. It is hoped that
this information may prove to be correct.

In regard to routes; the practicability of procuring needful supplies
for men and animals, and transporting baggage is a point to be well
considered. Should the president be disappointed in his cherished hope
that you will be able to reach the interior of Upper California before
winter, you are then desired to make the best arrangement you can for
sustaining your forces during the winter, and for an early movement in
the spring. Though it is very desirable that the expedition should reach
California this season (and the president does not doubt you will make
every possible effort to accomplish this object), yet if, in your
judgment, it cannot be undertaken with a reasonable assurance of
success, you will defer it, as above suggested, until spring. You are
left unembarrassed by any specific directions in the matter.

It is expected that the naval forces of the United States which are now,
or will soon be in the Pacific, will be in possession of all the towns
on the seacoast, and will co-operate with you in the conquest of
California. Arms, ordnance, munitions of war, and provisions to be used
in that country, will be sent by sea to our squadron in the Pacific for
the use of the land forces.

Should you conquer and take possession of New Mexico and Upper
California, or considerable places in either, you will establish
