however, against the heavier metal. The convent seemed a very volcano, enfolded in a dense cloud, and rumbling with the roar of artillery and rattle of musketry, the warning tones of messengers speeding forth on bloody trails, midst flashes of fire that lighted the scene as lightning-rays the storm. Beyond, along the distant hills rolled the echo of the thunder, reverberating in ever-feebler accents until it died in whispered moans; fading like the broken canopy of smoke that drifted in lazy indifference toward the icy summits of Iztaccihuatl.
Although the convent figured as centre point, the main effort of Scott was directed against the forces behind Rio Churubusco, in front and rear. The latter important movement was intrusted to the brigades of Shields and Pierce, which passed from Coyoacan north toward Portales, to turn the right flank of the reserve; but it was not undertaken with sufficient force,[1] for here stood the flower of the Mexican army, with the advantage of position. Santa Anna responded, moreover, by a prompt counter-advance, directing the cavalry to outflank the Americans, and compelling them to change the manœuvre to a more direct attack. This broke against the firm lines of the Mexicans, who sent the columns back staggering and in disorder. They quickly formed anew, however, to charge again and again. But in vain; their opponents repulsed every effort, and inflicted a terrible havoc with their steady fire, the Palmetto regiment alone leaving half its number on the field. And now the Mexicans, elated with success, pressed closer. The situation was becoming critical, and Shields sent a hurried appeal for aid. Just then a cry of alarm rose to the rear of Santa Anna's position, the prelude to a new phase of battle.
