last month, excepting only that the force intended to be sent by the 
Colonel, is something less than that reported to have accompanied 
him. He states that his party will be about 200 strong in rank and 
file, and adds " if necessary, it is expected that we can raise a con- 
siderable force among the Sioux." 
As Col. Leavenworth will probably report by express the result ot 
his movement, I have reason to expect it in the course of the next 
two weeks.

Dear Sir: I have just received a letter from General Ashley, 
giving information of an attack upon his party by tiie Auricara In- 
dians, by which it appears that not only the survivors of his party, 
but many other American citizens are in the most imminent danger, 
A copy of the General's letter I herewitli enclose, and, also, a copy 
of an order which I have issued on the subject. I can only add, that 
we shall leave here for our destination as soon as possible, which I 
hope will be to-morrow or next day. We shall take two six pounders 
and small swivels, and, perhaps, a howitzer. My party will be 
about 200 strong in rank and file. K necesssary, it is expected that 
we can raise a considerable auxiliary force amongst the Sioux. We 
shall do all we can to support the honor of your regiment, and hope, 
with the blessings of Heaven, to meet the approbation of our superi- 
ors and of our country. We go to cecure llie lives and property of 
our citizens, and to chastise and correct those who have committed 
outrages upoii them. It will be our endeavor to do this as peaceably 
as the nature of the circumstances which may occur will admit. 
I have the honor to be, with perfect respect. 
Your obedient servant, 
H. LEAVENWORTH, e^AiZf,^.
