On March 27, 1846, troops under the command of General Zachary Taylor advanced to a north bank of the Rio Grande and began construction of an earthen star fortress that they quickly nicknamed Fort Texas.
On May 3, Mexican artillery based in Matamoros began a week long bombardment of Fort Texas. While only two Americans were killed during the attack, the artillery barrage and the arrival of significant Mexican forces preventing reinforcement of the fortress placed the installation under great peril.
It was not until the Battle of Palo Alto that Mexican general Mariano Arista was forced to lift his siege of the fortress and retreat to the safety of Mexican territory.
