The number of American troops engaged at Churubusco on August 19th and 20th was four thousand five hundred.  The entire force engaged at Churubusco was about seven thousand four hundred.  General Scott’s estimate of the Mexican force on August 20th, including Contreras, Churubusco, and the road between San Antonio and Churubusco, the Portales, and the road to the Capitol, was thirty-two thousand.

In these battles three thousand prisoners were captured, including eight general officers and two hundred and five other officers.  The killed and wounded amounted to over four thousand.  Thirty pieces of cannon were taken.  The loss to the American army was one hundred and thirty-nine officers, including sixteen killed, and one thousand and fifty-three enlisted men; sixty officers and eight hundred and seventy-six men wounded.

Commodore William B. Shubrick having captured Mazatlan and Guaymas, General Scott wrote him, December 2, 1847:  “I have been waiting here for two and a half months to learn the views of the Government at home, or at least for re-enforcements, before undertaking any new and distant operations.  The forces I have under my orders in the whole of this republic, except the troops immediately under Major-General Taylor, only give me means of holding Tampico, Vera Cruz, Puebla, Chapultepec, and this capital.”

General Scott had made a careful study of the statistics of Mexican finances, and previous to ordering the occupation of several important districts near the capital, to be followed by a like disposition in more remote departments, issued General Orders No. 376, December 15, 1847: 

“(1) This army is about to spread itself over and to occupy the Republic of Mexico until the latter shall sue for peace on terms acceptable to the Government of the United States. (2) On the occupation of the principal point or points in any State the payment to the Federal Government of this republic of all taxes or dues of whatever manner or kind heretofore, say in 1844, payable or collected by that Government, is absolutely prohibited, as all such taxes, dues, etc., will be demanded of the proper civil authorities for the support of the army of occupation. (3) The State and Federal districts being already so occupied, as well as the States of Vera Cruz, Puebla, and Tamaulipas, the usual taxes or dues heretofore contributed by the same to the Federal Government will be considered as due and payable to this army from the beginning of the present month, and will early be demanded of the civil authorities of said States and districts under rules and penalties which shall be duly announced and enforced. (4) Other States of this republic, as the Californias, New Mexico, Chihuahua, Coahuila, New Leon, etc., already occupied by the forces of the United States, though not under the immediate orders of the general in chief, will conform to the prescriptions of this order, except in such State or States where a different system has been adopted
