Early the next morning, however, the reports of spies and the roar of Scott's heavy guns enlightened him. Troops were hurried to the real point of danger. With all speed he went there himself, ordered his best engineers to work on the fortifications near the main gateway of the Chapultepec enclosure, and posted troops close by. But there was little he could do. More and more accurately the American batteries fired and kept on firing. Two of the best cannon in the fort were disabled. The buildings of the college suffered, the garrison suffered more, and their morale suffered most of all, for except the engineers and gunners the men felt utterly helpless. When Santa Anna entered the rectangle unattended to reconnoitre, a shell burst near him and covered his red pony with dirt. Toward evening General Bravo, the commander of the position, came down, reported to him that the garrison were cowed, and demanded fresh troops; but Santa Anna could see no use of sending them forward to be destroyed on the way or else demoralized after arriving. They should be provided, he said, at the critical moment.[28.15] Scott saw, however, as the day waned, that Huger's expectations would not be realized--that an assault would be necessary. For this last resort preparations had in fact been made. The troops and the ladders were now ready. Fearing the Mexicans would repair the damages under cover of night he thought at first of delivering the blow at once; but he concluded that it was now too late in the day, that his guns could soon dispose of repairs and reinforcements, and that a morning attack would give many hours for pursuing the advantages gained. Engineers proceeded to mend and improve our own batteries, and the generals met for a conference. Here the plans were finally decided upon. Quitman's division and a forlorn hope of about 265 selected officers and men from Twiggs's division, under Captain Casey of the Second Infantry, were to advance by the Tacubaya road; and Pillow's, preceded by a similar party from Worth's division, led by Captain McKenzie of the Second Artillery, was to attack by way of El Molino and the grove. Then every one betook himself to his post. But Pillow felt discontented. "We shall be defeated," said Worth privately; and even Scott admitted to Hitchcock, "I have my misgivings."[28.16] [BATTLE OF CHAPULTEPEC] At daybreak--about half-past five--the next morning a signal gun broke the stillness, and then our batteries opened. For two hours or so they hurled shot and shells at the fort, and then for some thirty minutes grape, canister and shells were poured into the grove. At about eight o'clock, as if by common consent, they stopped--but only to burst forth again with new fury.[28.17]
