The Texan army moved quickly and silently across the high-grass plain, and then, when they were only a few dozen yards away, charged Santa Anna's camp shouting "Remember the Alamo!" and "Remember Goliad!," only stopping a few yards from the Mexicans to open fire. The Texans achieved complete surprise. It was a bold attack in broad daylight but its success can be attributed in good part to Santa Anna's failure to post guards during the army's siesta. Santa Anna's army primarily consisted of professional soldiers, but they were trained to fight in ranks, exchanging volleys with their opponents. The Mexicans were ill-prepared and unarmed at the time of the sudden attack. Most were asleep with their soldaderas (i.e., wives and female soldiers), some were out gathering wood, and the cavalrymen were riding bareback fetching water. General Manuel Fernández Castrillón desperately tried to mount an organized resistance, but was soon shot down and killed. His panicked troops fled, and Santa Anna's defensive line quickly collapsed.
Hundreds of the demoralized and confused Mexican soldiers were routed, with many being driven into the marshes along the river to drown. The Texans chased after the fleeing enemy, shouting "take prisoners like the Meskins do!", in reference to the burning of bodies after the Alamo and the mass murder of Texans at Goliad. Some of the Mexican cavalry plunged into the flooded stream by Vince's bridge but they were shot as they struggled in the water. Houston tried to restrain his men but was ignored. Gen. Juan Almonte, commanding what was left of the organized Mexican resistance, soon formally surrendered his 400 remaining men to Rusk. The rest of Santa Anna's once-proud army had disintegrated into chaos. From the moment of the first charge the battle was a slaughter, "frightful to behold", with most of the Texan casualties coming in the first minutes of battle from the first Mexican volley.[8]
During the short but furious fighting, Houston was shot in the left ankle, two of his horses were shot from under him, and Santa Anna escaped. The combat itself lasted 18 minutes but the slaughter of the Mexicans continued for "another hour or so".[3][9] The Texan army had won a stunning victory, killing about 700 Mexican soldiers, wounding 208, and taking 730 prisoners while suffering 9 killed and 30 wounded.[10]
