On April 19, learning that Santa Anna and his army had crossed Vince’s Bridge to the west bank of the San Jacinto River, Houston and his men crossed Buffalo Bayou. On April 20, the Texans encamped. That afternoon, Sidney Sherman with a small detachment of cavalry fought a brief skirmish with the Mexican infantry in an attempt to capture the Mexican cannon. Santa Anna was joined in his camp, three-quarters of a mile from the Texan army, by a 540-man unit commanded by Martin Perfecto de Cos on the evening of April 20. On Thursday morning, Houston ordered Erastus (Deaf) Smith to destroy Vince’s Bridge secretly so that no further reinforcement could cross nor could either army retreat. The Texans formed their battle line about 3:30 in the afternoon. Surging over the battlefield shouting “Remember the Alamo!” and “Remember Goliad!”, the Texans caught the Mexican army unawares. The battle ended with a decisive victory eighteen minutes after it began. Sam Houston was seriously wounded in the battle. General Santa Anna was captured the next day.
