Late on March 30 news that Vera Cruz had fallen reached the capital. At once the government expelled Black, the American consul residing at Mexico, and issued a circular calling upon all citizens to forget rancor and dissension, offer their lives and fortunes, and stand unitedly behind the President. "Mexicans," exclaimed Santa Anna, "do not hesitate between death and slavery.... Awake! A sepulchre opens at your feet; let it at least be covered with laurels!" and he adjured Canalizo in the name of the country to fortify Corral Falso and Cerro Gordo, and above all to defend the national bridge "in all possible ways and at all costs" in order to give time for troops to concentrate above it. With Senobio's forces and the militia--amounting, said this letter, to more than 2000 men--and aided by the topography of the ground, itself "equal in value to an army," the enemy could be detained, the President assured him; and he was authorized to shoot every deserter and every coward. At the same time Governor Soto was directed to proclaim martial law, call out all the fit men between the ages of fifteen and fifty years, and aid Canalizo in every possible way. Then, after transferring the executive power to General Anaya, the substitute President, Santa Anna left the capital on April 2. As he went down the steps of the palace to his waiting carriage, he and the onlookers felt sad presentiments they could not hide. Even his enemies had tears in their eyes, and it seemed to every one like a final good-by.[23.9] [SANTA ANNA AT THE FRONT] On the way gloomy reports met him. Soto wrote that while all in his power had been done, the fate of Vera Cruz had smitten the people with terror, and the resources of the state were far from adequate. Canalizo wrote no more hopefully. Efforts had been made to rouse the spirit of the public.[23.8] Under penalty of death all intercourse with the Americans had been prohibited, and under the same threat all citizens had been ordered to place beyond the invader's reach whatever could be of service to him. But the outlook was dark. Although a good engineer had been at the national bridge for a week, work on the fortifications had scarcely begun; eight hundred out of a thousand men had fled panic-stricken on learning of Scott's triumph at Vera Cruz, there was little ammunition or money, and the bridge could not be held. In view of Santa Anna's adjuration Canalizo promised to make another effort, but he soon ordered La Vega to abandon the position. The light fortifications recently built were demolished, and as wagons to carry the guns away could not be obtained, they were spiked and pitched into a ravine.[23.9]
