Explain the “Black Bean Incident.” Who was involved and why? What was the outcome?

During the Mexico-Texas conflict, President Houston sent out troops to make certain that all Mexican forces were out of San Antonio. A Texan army led by Colonel William S. Fisher ignored orders to return to Gonzales and attacked the Mexican town of Mier. Although they put up a good fight, the Texan army was outnumbered and captured as prisoners. The prisoners were taken back to Mexico City. They escaped, but many were recaptured only a week later. Santa Anna ordered the execution of every 10th prisoner whose fate was to be chosen by lottery. Every prisoner had to take a bean out of a jar; if he chose a black bean, he would be executed. Santa Anna executed 17 men who drew black beans. The remaining prisoners were taken to Perote prison and later released.
