Special Message

To the Senate of the United States:

In answer to a resolution of the Senate of the 13th January, 1848, calling for information on the subject of the negotiation between the commissioner of the United States and the commissioners of Mexico during the suspension of hostilities after the battles of Contreras and Churubusco, I transmit a report from the Secretary of State and the documents which accompany it.

I deem it proper to add that the invitation from the commissioner of the United States to submit the proposition of boundary referred to in his dispatch (No. 15) of the 4th of September, 1847, herewith communicated, was unauthorized by me, and was promptly disapproved; and this disapproval was communicated to the commissioner of the United States with the least possible delay.

JAMES K. POLK.
