The corps d'armée placed under the command of General Rubio, and shut up with him in Galveston, only amounted to nine hundred and fifty officers and men, to whom might be found at a given signal some three hundred lanceros scattered in little posts of observation along the coast. Though incapable of effectually defending the town, this force, well directed, might hold in check for a long time the worse armed, and certainly worse disciplined insurgents.
The General had rapidly seen the value of the Colonel's advice. The plan the latter proposed was, in truth, the only practicable one, and hence he accepted it at once. Still, it was necessary to act with vigour; the sun was rising, and the coming day was Sunday; hence it was important that the army should have evacuated the town before the end of mass, that is to say, eleven in the morning, for the following reason:
In all the slave states, and especially in Texas, a strange custom exists, reminding us distantly of the Lupercalia of ancient Rome. On a Sunday masters grant their slaves entire liberty; one day in seven is certainly not much; but it is a great deal for the Southern States, where slavery is so sternly and strictly established. These poor slaves, who seek compensation for six days of hard servitude, enjoy with childish delight their few holiday hours: not caring a whit for the torrid heat that transforms the streets into perfect ovens, they spread over the town singing, dancing, or galloping at full speed in carts belonging to their masters which they have appropriated. On this day the town belongs to them, they behave almost as they please, no one interfering or trying to check their frolic.
General Rubio rightly feared lest the merchants of Galveston, whom he had so cleverly compelled to disgorge, might try to take their revenge by exciting the slaves to mutiny against the Mexicans, and they would probably be ready enough to do so, delighted at finding a pretext for disorder, without troubling themselves further as to the more or less grave results of their mutiny. Hence, while his aide-de-camp performed the commission he had entrusted to him, General Rubio ordered Colonel Melendez to take with him all the soldiers on duty at the Cabildo, place himself at their head, and seize the requisite number of boats for the transport of the troops to the main land.
This order was not difficult to execute. The Colonel, without losing a moment, went to the port, and not experiencing the slightest opposition from the captains and masters of the vessels, who were well aware, besides, that a refusal would not be listened to, assembled a flotilla of fifteen light vessels, amply sufficient for the transport of the garrison. In the meanwhile, the aide-de-camp had performed his duties with intelligence and celerity, so that within twenty minutes all the Mexican officers were collected at the General's house.
The latter, without losing a moment, explained to them in a voice that admitted of no reply, the position in which the capture of the fort placed the garrison, the necessity of not letting the communication with the mainland be cut off, and his intention of evacuating the town with the least possible delay. The officers, as the General expected, were unanimous in applauding his resolution, for in their hearts they were not at all anxious to sustain a siege in which only hard blows could be received. Taking the field pleased them, on the contrary, for many reasons: in the first place, the pillage of the estancias and the haciendas offered them great profits, and then they had a hope of taking a brilliant revenge on the insurgents for the numerous defeats the latter had inflicted on them since they had been immured in the town.
Orders were therefore immediately given by the General to march the troops down to the quay with arms and baggage; still, in order to avoid any cause for disorder, the movement was executed very slowly, and the Colonel, who presided over the embarkation, was careful to establish numerous posts at the entrance of each street leading to the port, so that the populace were kept away from the soldiers, and no disputes were possible between them. So soon as one boat had its complement of troops on board it pushed off, though it did not start, as the General wished the entire flotilla to leave the town together.
It was a magnificent day, the sun dazzled, and the bay sparkled like a burning-glass. The people, kept at a distance by the bayonets of the soldiers, watched in gloomy silence the embarkation of the troops. Alarmed by this movement, which they did not at all understand, and were so far from suspecting the departure of the Mexican garrison, that they supposed, on the contrary, that the General was proceeding with a portion of his troops to make an expedition against the insurgents.
When all the soldiers, with the exception of those intended to protect the retreat of their comrades, had embarked, the General sent for the alcade mayor, the Juez de letras, and the corregidor. These magistrates came to the General, concealing, but poorly, under a feigned eagerness, the secret alarm caused them by the order they had just received. In spite of the rapidity with which the troops effected their embarkation, it was by this time nearly nine o'clock. At the moment when the General was preparing to address the magistrates whom he had so unexpectedly convened, Colonel Melendez entered the cabildo, and after bowing respectfully to the Governor, said—
"General, the person to whom I had the honour of referring last night is awaiting your good pleasure."
