The Siege of Fort Texas marked the beginning of active campaigning by the armies of the United States and Mexico during the Mexican-American War. The battle is sometimes called The Siege of Fort Brown, but this is not entirely accurate — the name Fort Brown was taken from Major Jacob Brown, who was one of the two Americans killed during the engagement. Major Jacob Brown should not to be confused with the War of 1812 hero Jacob Brown.
On 28 March 1846, the Army of Occupation under the command of General Zachary Taylor reached the north bank of the Rio Grande and he ordered Captain Joseph K. Mansfield to construct of an earthen star fortress for 800 men named "Fort Texas".:40 The fort was garrisoned by 500 men under Major Jacob Brown, including the 7th Infantry, Capt. Allen Lowd's four 18 pounders, and Lt. Braxton Bragg's field battery.:49.
General Francisco Mejia's 2000 men erected fortifications for his twenty pieces of artillery, an earthwork for 800 men upstream at the Las Anacuitas ferry crossing called Fort Paredes, and two redoubts about 800 yards from Taylor's camp placing it in a crossfire.:40 The largest cannon was a 12 pounder.:40
Following the Thornton Affair, Mexican forces under General Mariano Arista crossed the Rio Grande and then lay siege to the fort,:49 after realizing Taylor had taken most of his forces to Fort Polk on Point Isabel to protect his supply depot on 1 May.:50
At daylight on 3 May 1846, Mexican forces started the bombardment of Fort Texas, but were silenced by the American response, although the Mexican artillery down the river was more successful.:50 Lowd attempted to set fire to Matamoros with "hot shot".:50 Mexican fire stopped at 7:30 PM, the American's at 11 PM.:50 On 4 May, Mexican guns and a mortar were placed on the northern bank of the Rio Grande and on 5 May General Pedro de Ampudia arrived with 1,230 men and four guns.:50 Since Ampudia's artillery was too light to breach the earthworks and the infantry disinclined to make an assault, the siege continued until 9 May with General Antonio Canales Rosillo's irregular cavalry astride the Point Isabel road preventing supplies from reaching the fort.:50
Captain Edgar S. Hawkins took command of Fort Texas when Major Brown was mortally wounded on 6 May at ten o'clock.:50 When Arista demanded the fort's surrender at 4:30 that afternoon, Hawkins responded withm "My interpreter is not skilled in your language but if I understand you correctly...I must respectfully decline to surrender.":52
As soon as it became clear Taylor was leaving Fort Polk, Arista moved his army from his camp at Tanques del Ramiereno to block Taylor's path leading to the battles of Palo Alto and Resaca de la Palma.:52
Though the confrontation at Fort Texas lasted six days, with periods of heavy cannon fire, casualties were remarkably low. Only two U.S. soldiers died in the bombardment. Major Brown was struck in the leg by a cannonball on May 6 and survived for several days only to die on May 9, just hours before the siege ended. Despite his wound, Brown had helped maintain troop morale throughout the siege, thus contributing to the success of the defense of the Fort. Mexican leaders reported two killed and two wounded from American artillery fire during the siege. The effect of artillery fire on the civilian population of Matamoros is unknown. Laundress and cook Sarah Borginnes, who refused to take shelter during the siege but instead provided food and coffee to the American troops, was named "Heroine of Fort Brown" by the American newspapers.
