At approximately 5 A.M. on March 6, 1836, four columns totaling about 1,100 Mexican troops move into postion to begin the assault on the Alamo. 

From the northwest: General Martín Perfecto de Cós with two hundred fusiliers and rifleman of the Aldama Battalion and one hundred fusilers of the San Luis Potosi militia carrying ten ladders, two crowbars, and two axes. 

From the north: Colonel Francisco Duqué with the Toluca Battalion (minus the grenadiers) and three fusilier companies of San Luis, about four hundred men in all, carrying ten ladders, two crowbars, and two axes.

From the northeast: Colonel José María Romero with fusilier companies of the Matamoros and Jimenez battalions, about thre hundred men, carrying six ladders.

Mauled by Alamo artillery and small-arms fire, the columns on the east, north, and west waver and fall back. The southeren column seeks shelter behind the jacales at the southwest corner.
