General Rubio understood how important it was for him to deal a heavy blow before his junction with the President, who, while following his advice, would not fail, in the event of defeat, to attribute the reverses to him, while, if the Mexicans remained masters of the field, he would keep all the honour of victory to himself.
The Texan insurgents had not up to this moment dared to measure themselves with the Mexican troops in the open field, but the events that had succeeded each other during the last few days with lightning speed, had, by accelerating the catastrophe, completely changed the aspect of affairs. The Chiefs of the revolutionary army, rendered confident by their constant advantages, and masters without a blow of one of the principal Texan seaports, felt the necessity of giving up their hedge warfare, and consolidating their success by some brilliant exploit.
To attain this end, a battle must be gained; but the Texan Chiefs did not let themselves be deceived by the successes they had hitherto met with, successes obtained by rash strokes, surprises, and unexampled audacity; they feared with reason the moment when they would have to face the veteran Mexican troops with their inexperienced guerillas. Hence they sought by every means to retard the hour for this supreme and decisive contest, in which a few hours might eternally overthrow their dearest hopes, and the work of regeneration they had been pursuing for the last ten years with unparalleled courage and resignation. They desired, before definitively fighting the regulars, that their volunteers should have acquired that discipline and practice without which the largest and bravest army is only an heterogeneous compound of opposing elements, an agglomeration of men, possessing no consistency or real vitality.
After the capture of the fort a grand council had been held by the principal Texan Chiefs, in order to consult on the measures to be taken, so as not to lose, by any imprudence, results so miraculously obtained. It was then resolved that the army should occupy Galveston, which its position rendered perfectly secure against a surprise; that the freebooters should alone remain out to skirmish with the Mexicans and harass them; while the troops shut up in the town were being drilled, and receiving a regular and permanent organization.
The first care of the Chiefs, therefore, was to avoid any encounter with the enemy, and try to enter Galveston without fighting the Mexicans. The following was the respective position of the two armies; the Texans were trying to avoid a battle, which General Rubio was lodging, on the contrary, to fight. The terrain on which the adversaries would have to manoeuvre was extremely limited, for scarce four leagues separated the videttes of the two armies. From his observatory the General could clearly distinguish the camp fires of the rebels.
In the meanwhile Colonel Melendez had continued to advance; on reaching the cross where he and John Davis had fought so furiously on the previous evening, the Colonel himself examined the ground with the utmost care, then, feeling convinced that none of the enemy's flankers had remained ambushed at this spot, which was so favourable for a surprise, he gave his men orders to dismount. The horses were thrown down, secured, and their heads wrapped in thick blankets to prevent their neighing, and after all these precautions had been taken, the soldiers lay down on their stomachs among the shrubs, with instructions not to stir.
General Rubio had himself effected a flank march, which enabled him to avoid the crossways; immediately after descending the hill, he marched rapidly upon the river bank. We have said that the Rio Trinidad, which is rather confined at certain spots, is bordered by magnificent forests, whose branches form on the bank grand arcades of foliage overhanging the mangroves; it was among the latter, and on the branches of the forest trees, about two gunshots from the spot where he had landed, that the General ambuscaded about one-third of his infantry. The remainder, divided into two corps, were echeloned along either side of the road the Insurgents must follow, but it was done in the American fashion, that is to say, the men were so hidden in the tall grass that they were invisible.
The four mountain howitzers crowned a small hill which, through its position, completely commanded the road, while the cavalry was massed in the rear of the infantry. The silence momentarily disturbed was re-established, and the desert resumed its calm and solitary aspect. General Rubio had taken his measures so well that his army had suddenly become invisible.
When it was resolved in the council of the Texan Chiefs that the Insurrectionary army should proceed to Galveston, a rather sharp discussion took place as to the means to be adopted in reaching it. The Jaguar proposed to embark the troops aboard the corvette, the brig, and a few smaller vessels collected for the purpose. Unfortunately this advice, excellent though it was, could not be followed, owing to General Rubio's precaution of carrying off all the boats; collecting others would have occasioned an extreme loss of time; but as the boats the Mexicans had employed were now lying high and dry on the beach, and the guard at first put over them withdrawn a few hours later, the Texans thought it far more simple to set them afloat, and use them in their turn to effect the passage.
By a species of fatality the council would not put faith in the assertions of John Davis, who in vain assured them that General Rubio, entrenched in a strong position, would not allow this movement to be carried out without an attempt to prevent it; so that the abandonment of the boats by the Mexicans was only fictitious, and a trap adroitly laid to draw the Revolutionists to a spot where it would be easy to conquer them.
