The American president wasprepared to purchase Mexican territory, buthe was also prepared, if necessary, to take itby force. To add to the tension there was a disputeover the location of the southern boundaryof Texas. The Texans claimed it was theRio Grande River; the Mexicans said it wasthe Nueces River, in some places 140 milesfurther north. In the spring of 1846, Polk sent troops tothe area. An American army under GeneralZachary Taylor crossed the Nueces andheaded south to the Rio Grande. At the sametime a Mexican army crossed the Rio Grandeand headed north to the Nueces, In lateApril the armies clashed in the first battle ofthe war. An overconfident Mexican governmentdeclared war on the United States on 23 April1846, believing that their experiencedmilitary forces could crush the impudentAmericans and their minuscule regular army,lhis was to be a fatal mistake. On 13 May 1846, the Congress of theUnited States declared war on Mexico afteran address by President Polk in which hepronounced: American blood has been shedon American soil.

(Gerry Embleton) the government, quickly asserted their right to smuggle. Soon their schooners sailed past Mexican customhouses, sometimes exchanging gunfire, and the increasing friction led to hloody skirmishes between Texan militia and Mexican regulars. In an effort to redress grievances, Texas settlers called a convention and chose Stephen F. Austin to travel to Mexico City with proposals that they hoped would end the conflicts. After long wrangling with the Mexican government, Austin was imprisoned for treason. After two years in confinement he was released, on Christmas Day 1834, and returned to Texas. Santa Anna, now dictator of Mexico, abrogated the liberal Mexican constitution of 1824 and ordered that all Texans be disarmed. The Texans refused to give up their weapons and clashes again broke out between the Anglo settlers and the Mexican soldiers. In 1836, Santa Anna determined to establish control over the rebellious colony. At the head of an army he crossed the Rio Grande and invaded Texas. He overran the defenses of the old Alamo mission in San Antonio and slaughtered the few wounded survivors. On his orders a band of more than 300 rebels who had surrendered at the town of Goliad were summarily shot. On 2 March 1836, the Texans, having assembled in convention, issued a declaration of independence, severing their ties with Mexico and declaring themselves an independent republic. On 20 April 1836, a furious and shrieking Texan army destroyed Santa Annas forces at the battle of San Jacinto. When captured, in order to save his neck from a hangmans noose, Santa Anna signed the Treaty of Velasco, granting Texas independence. The Mexican government refused to recognize the treaty, however, drove Santa Anna into exile, and maintained that Texas was still a province of Mexico.

In November 1845, Polk sent John M.Slidell to Mexico City with an offer to buy allMexican lands from the Texas border to thePacific Ocean. He offered $25,000,000. Aspart of the deal, the American governmentwould also pay to American citizens theclaims they held against Mexico. The Americans considered this offer tobe more than fair. After all, Texas hadmaintained its independence for a decadeand the other western lands were mostlyvacant except for scattered Indian tribes andAmerican squatters, furthermore, theAmericans claimed that these lands wereonly nominally held by Mexico, whosegovernment was unable to exercise anyauthority over them.

If American campaigns were won bygenerals, during the war with Mexico, battleswere won through the excellence of juniorofficers, and if there was one determinantfactor in American successes, it was the UnitedStates Military Academy at West Point, in NewYork State. The discipline and trainingdelivered there, particularly in engineering andin the use of light artillery, turned the tide ofmany of the fiercest battles of the war. Amongits graduates was Robert E. Lee, arguably themost gifted commander in all of Americaswars. It was his personal reconnaissance workthat made great contributions to Americanvictories at Buena Vista, Vera Cruz, and Scottssuccessful campaign on the road to MexicoCity.

  22. 22. 24 Essential Histories * The Mexican War selected by lot for a six-year tour of duty. Bachelors and married men without children from 18 to 40 years of age were required to serve. Middle-class men with piolitical connections could usually gain an exemption if they did not wish to be officers. Unlike the robust Americans, most of whom were farmers raised on a diet of fresh meat, wheat bread, and vegetables, the Mexican soldier was often less than five feet two inches tall and was poorly fed on a diet of Indian corn, rice, and beans. Compounding the confusion of inadequate training, most of the peasant soldiers were illiterate; many spoke and understood only the Indian dialects of their tribe. If the Americans could be combative over military discipline, the Mexican soldier simply deserted.

On the hot, muggy morning of 8 May, Taylors sweat-soaked men stomped along the sandy road until they came to a halt one mile from the enemy. Taylor, wearing his customary baggy blue jeans, a stained white duster, and a battered straw hat, looked more like a down-on-his-luck farmer than a commanding general. Sitting sidewise on his horse and occasionally spitting an amber stream of tobacco juice, Taylor calmly deployed his men. With the exception of the mounted Texas Rangers, they were all regulars. Taylors immediate concern was his supply train - 300 cumbersome wagons being hauled by a motley assortment of mules and oxen. To protect them from a lightning attack by Mexican cavalry, he reluctantly diverted a battery of artillery and a squadron of dragoons. Taylor placed his large 18-pounder guns in the center of the road and moved his troops to form a line of skirmishers. He placed the 8th Infantry Regiment on his far left flank, supported by Captain James Duncans light artillery battery. In the center, straddling the 18-pounders, he deployed the 3rd and 4lh Infantry Regiments. To their right he placed Major Samuel Ringgold and his battery, supporting the 5th Infantry Regiment on the extreme right flank. Ringgold, like many young West Point graduate artillerists, was eager to test his new Flying Artillery, lightweight, horse drawn-guns designed to be deployed and fired rapidly.

Arista then ordered his remaining cavalry to flank the American left and destroy the American wagon park. They met with equally devastating artillery fire from Duncans battery and quickly withdrew to their lines. The constant firing set the prairie grass afire and soon oily black smoke enveloped the battlefield. Under this cover, Arista ordered a withdrawal. As the Mexicans retreated, they could hear the screams of their wounded, burning to death in the flaming grass.

Polk agreed, and in August 1846, Santa Anna arrived in Mexico. True to his character, Santa Anna double-crossed Polk, denounced the Americans, seized power in Mexico City, and began raising new armies to drive the gringos out of Mexico. Alexander W.
