From General Scott’s report we learn that the loss in his army in the various engagements around and in the City of Mexico amounted to two thousand seven hundred and three.  The whole force engaged in the capture of the capital was less than six thousand.  The Mexicans admit that their force for the defense of the capital was about twenty thousand, with one hundred and four cannon.  The Mexican army encountered by General Scott on his move to the capital was not less than thirty thousand.  In nearly if not quite all of the engagements they were intrenched, and occupied their own chosen positions.  Of these, the American army killed or wounded not less than seven thousand officers and men, captured three thousand seven hundred and thirty prisoners, more than twenty colors and standards, seventy-five pieces of ordnance, besides fifty-seven wall pieces, twenty thousand stand of small arms, and a large quantity of ammunition.

Following are orders issued by General Scott after the occupation of the capital: 

“HEADQUARTERS OF THE ARMY, NATIONAL PALACE OF MEXICO,
“September 16, 1847.

“GENERAL ORDERS NO. 286.

“The general in chief calls upon his brethren in arms to return, both in private and public worship, thanks and gratitude to God for the signal triumph which they have recently achieved for their country.  Beginning with August 10th and ending the 14th inst., this army has gallantly fought its way through the fields and forts of Contreras, San Antonio, Churubusco, Molino del Rey, Chapultepec, and the gates of San Cosme and Tacubaya, into the capital of Mexico.  When the very limited number who have performed these brilliant deeds shall have become known, the world will be astonished and our own countrymen filled with joy and admiration.  But all is not yet done.  The enemy, though scattered and dismayed, has still many fragments of his late army hovering about us, and, aided by an exasperated population, he may again unite in treble our numbers and fall upon us to advantage if we rest inactive in the security of past victories.  Compactness, vigilance, and discipline are therefore our only securities.  Let every good officer and man look to these cautions and enjoin them on all others.

“By command of Major-General Scott.

“H.L.  SCOTT,

“Acting Assistant Adjutant General.”
