Edwin L. Sabin,
Into Mexico with General Scott
(1920)
“ But this day they all were to cross the range and would see the City of Mexico below, where General Santa Anna waited with his thirty thousand men, his artillery and his forts.To drum beat and fife note, playing the regimental marches, the First Division stepped out briskly in the crisp air. The way was up, and up, and up. At every half mile the column had to stop and rest. The men sweat under their muskets, knapsacks, haversacks, cartridge boxes and blanket rolls. When they reached the top they were almost eleven thousand feet aloft. ”
