The besieged within the fortress were calm and confident, though they were kept day and night at rifle and cannon. But they were fighting at fearful odds. Travis sent out an impassioned appeal to the council for aid. He also dispatched Colonel Bonham to Goliad, asking for Fannin’s assistance. At the same time he proudly wrote: “I shall never surrender or retreat.” On the eighth day of the siege thirty-two volunteers from Gonzales succeeded in passing the Mexican lines and entered the fort. Two days later Colonel Bonham slipped in alone, but bringing news that Fannin would march at once with men and artillery. On the 1st of March Travis wrote to the council; it was his last letter. “I shall continue to hold this place,” he said, “until I get relief from my countrymen, or I shall perish in the attempt.” But steady as was his spirit, he could not shut his eyes to the fact that the desperate game was well-nigh played out. On the 4th of March he called his men together and made them a short but ringing speech. There was, he told them, no longer any hope of reinforcements; death was staring them all in the face, and nothing remained but to sell their lives as dearly as possible. “Now,” he concluded, drawing a line on the ground with his sword, “whoever is willing to die like a hero, let him cross this line.” There was not a moment of hesitation. Gravely and silently, one by one, the men, with one exception,[22] stepped across the line and ranged themselves beside their leader. Bowie, who was sick, had himself lifted over in his cot. Sunday morning, March 6, between midnight and dawn, the final assault was made by the besiegers. The Mexican bugles sounded the notes of _Duquelo_ (no quarter); the thunder of cannon followed. The devoted little band of Texans, weary and worn with constant watching and incessant fighting, sprang to arms as cheerfully and quickly as to a holiday parade. The Mexicans, two thousand five hundred strong, closed about the walls. They were provided with scaling ladders, axes, and crowbars. A cordon of cavalry was placed around the fort to prevent escape. The enemy advanced in the gray dawnlight, under a deadly fire from the fort. Twice they placed their ladders against the walls, and twice they recoiled before the terrible hail of shot and shell poured upon them from the fort. The third time, driven by their officers at the point of the sword, the soldiers climbed the walls and swarmed over into the enclosure. Then began a stubborn and bloody combat, which strewed the plaza with corpses. The Texans fought grimly, silently, furiously, with pistols, with knives, with the butts of their rifles, dropping one by one, but sending as they fell scores of Mexicans to a bloody death.
