Mexican forces under General Antonio Lopez de Santa Anna continued to sweep across Texas toward Fort Defiance, the presidio in Goliad that had been seized by the rebels in October 1835 at the onset of the war for independence. Houston ordered Colonel James W.

It was adopted by other States primarily to help the children who were left by their fathers and orphans, and dependent mothers.
