Some accounts say the engagement occurred September 18, but Caldwell's own report of the battle contradicts this. Knowing he was outnumbered, he ordered some of his militia to lure the Mexicans out of the fortified city and into the prairie around Salado Creek. The remaining Texians were positioned in the creek bed where they had good cover. Caldwell never anticipated victory but knew that from their protected position his men could cause considerable damage to the Mexicans without being too exposed to enemy fire. The Texians could find only thirty-eight horses fit for duty so only thirty-eight men could be sent to decoy the Mexicans. Captain
John C. Hays, his fourteen Texas rangers,
Henry E. McCulloch,
William A. A. Wallace,
Robert Addison Gillespie and sixteen others were assigned to the mission. The thirty-eight men were sent from the Salado to San Antonio on the morning of September 17, arriving outside the city sometime at dawn. Hays ordered his men to dismount and prepare an ambush while he and eight others proceeded to within a half-mile of Woll's base at the
Alamo. Hays hoped to lure out around fifty of the Mexicans but, when the Texians were spotted, 200 Mexican cavalrymen and forty Cherokees were sent after them followed by about 300 more men led by Woll himself. Hays ordered an immediate retreat back to the creek where a running battle ensued. The Mexican cavalry attempted to cut Hays' command off from the right but the Texians managed to get back to the Salado, closely pursued. Over 200 shots were fired during this first skirmish though the Texians sustained no casualties. When Hays reached camp the men were preparing for breakfast, which was quickly stopped so as to take up positions for defense. After seeing the Texian camp, the cavalry chose to break off the pursuit and form a line of battle on the opposite side of the creek, in the prairie southeast of Caldwell's men. When over 1,000 Mexicans and Cherokees were assembled, they began firing across the creek with volleys of musket and cannon fire. Though accurate, the artillery barrage was ineffective throughout the five-hour battle because of the distance at which they were being fired from. According to one Texian named N. B. Burkett, the Texians "
did not pay a great deal of attention to them." Caldwell then sent for reinforcements from several nearby towns. His distress call said that he was surrounded, but was confident that he was in no threat of being defeated and could hold his position. Another few sentences of Caldwell's message read: "''The enemy are around me on every side, but I fear them not. I will hold my position until I hear from reinforcements. Come and help me—it is the most favorable opportunity I have ever seen. There are eleven hundred of the enemy. I can whip them on any ground, without any help, but can not take any prisoners. Why don't you come? Huzza! huzza for Texas!''" The battle took the form of skirmishing for several hours as Caldwell directed his sharpshooters to constantly harass the Mexican line, then retreat back to the creek before being discovered. These tactics severely annoyed the Mexicans, who were dying left and right while inflicting only few casualties upon the Texians. Eventually General Woll ordered a full attack with his left and right wings, and so the Mexicans advanced; but they were repulsed within fifteen minutes. Some of the Mexicans made it to twenty steps from the Texian line before being killed. After this failed attack, Woll attempted to rally his men for another, but could not. Later that night, he retreated south toward the border. Woll managed to complete a successful withdrawal by igniting several camp fires to deceive the Texians as to their withdrawal. But when some of Caldwell's men attempted to skirmish with the Mexicans that night, they discovered that Woll had retreated. The battle was over. ==Aftermath==
