General Scott appointed as commissioners Major General John A. Quitman, Brigadier-General Franklin Pierce, and Brevet Brigadier-General Persifor F. Smith.  The convention concluded its work on the 24th of August.  It was agreed that hostilities should cease at once within thirty leagues of the Mexican capital.  No work of a military character was to be done, and any re-enforcements or munitions of war except that now on its way to either army was to be stopped at a distance of twenty-eight leagues from the capital.  The American army was not to obstruct the passage from the surrounding country into the capital of the ordinary supplies of food necessary for the subsistence of the Mexican army and the inhabitants within the city, nor were the Mexican authorities to obstruct the passage of supplies of subsistence from the city or country necessary for the supply of the American army.  The armistice was to continue pending negotiations or until the commander of either army should give notice to the other of its cessation; and forty-eight hours after such notice General Worth, on the night of the 21st, moved his division to Tacubaya, where he was preceded by General Scott, and established his headquarters in the Bishop’s Palace.  General Quitman remained at San Augustin, to which point General Shields returned with his command.  General Twiggs was at San Angel, and General Pillow at Mexcoac.

Previous to the occurrences just narrated, Major Folliot Thornton Lally had on August 6th marched with a force of about one thousand men from Vera Cruz.  He was joined en route by a company of mounted Georgia volunteers, one of Louisiana mounted men, and two six-pounders, under command of Lieutenant Henry B. Sears, of the Second Artillery.  General Don Juan Soto, Governor of the State of Vera Cruz, organized a force between one thousand and two thousand strong, a part of which were paroled prisoners, with the purpose of attacking Major Lally and capturing his wagon train, which was supposed to carry a large amount of silver coin.  An attack was made by this force on Major Lally at the pass of Ovejas, the engagement lasting an hour and a half.  Captains James Nelson Caldwell, of the Voltigeurs, and Arthur C. Cummings, Eleventh Infantry, were severely wounded.  Nine enlisted men were wounded, one mortally.  The Mexican loss is not known.  On August 12th the command reached Puente Nacional and found the Mexicans in considerable force, strongly barricaded.  An artillery fire was opened on them and they were driven back.  The American loss in this affair was sixty killed and wounded.  On approaching the battlefield of Cerro Gordo they were again attacked, and sustained a loss of one killed and eight wounded.  Several other attacks of a similar character were made, but without success.  Major Lally, with his troops and wagon train, arrived at Jalapa thirteen days out from Vera Cruz, when without interruption five days would have been sufficient for the march.  Mr.
