As the night wore away, a heavy mist swept up the river, and even when dawn came but little could be seen. Yet, anxious to avenge the loss at Gonzales, the Mexicans opened fire at once, which, however, did no harm. As the mists cleared away, the Mexican cavalry surrounded the whole front of the Texans' position. "Give it to 'em!" shouted the Texan officers. "Give it to 'em hot!" The cry was drowned out by a solid fire from the Mexicans, who continued to pour in volley after volley just as fast as they could reload. The Texans did not fire by volleys. The orders were: "Fire at will, and make every shot bring down a greaser!" And there was a constant crack! crack! and the Mexicans were seen to fall in all directions. Lieutenant Radbury now found himself under actual fire, and instantly his mind took him back to his service in the war of 1812. He carried a rifle as well as a pistol, and did as good work as any man on the field. "They are preparing for a charge! They are bringing up a cannon!" was the cry that soon rang along the line, and then the Mexican bugler sounded out the command, and the cavalry came on with a rush calculated to sweep everything before it. But the Texans stood firm. "Drop 'em!" roared Colonel Bowie. "The first line, boys!" And a score of shots rang out, and the first row of saddles was emptied almost completely. Some of the horses were killed or wounded, and these, falling, caused some confusion. In the meantime, other Mexicans continued to drop, and soon the cavalry retreated to reform. "Now they are going to use the cannon!" was the cry which went up directly afterward, and then a four-pounder, stationed on a bluff, was discharged. The cannon was aimed much too high, and it is said that every shot from the piece went over the Texans' heads. The cavalry now came on again, and it was seen that the Mexicans intended to shift the position of the cannon so that they might enfilade the line,--that is, shoot from one end to the other. "Not much ye don't!" sang out Poke Stover, and, leaping to a slight knoll, he took careful aim at one of the mules attached to the piece and fired. Then he discharged his pistol at a second mule. Both beasts were badly wounded, and, breaking away, they tore first through the cavalry and then through the infantry, throwing the latter into much confusion. "We have 'em on the run!" Like magic the cry arose from nearly every Texan's throat. The cavalry had charged again, and again the leading line had gone down. Now they were retreating, with the infantry beside them. Seeing it was of no use to remain longer, the cannoneer attempted to spike the four-pounder, but a Texan sharpshooter cut him down in the act.
