General Taylor’s Campaign

January 13, 1846, General Taylor is directed by the President to advance and occupy the left or Texas bank of the Rio Grande River; he has been reinforced by recruits, and is authorized to apply to the Southern States for volunteer troops.

March 8 the first detachment is started forward to cross the disputed strip between the Nueces River and the Rio Grande. Other detachments follow. Part way General Taylor is officially warned by a Mexican officer that a farther advance will be deemed a hostile act. He proceeds, with his 4000 Regulars (half the army of the United States), and establishes a base of supplies at Point Isabel, on the Gulf shore, about thirty miles this side of the Rio Grande River.

March 28 the American army of now 3500 men, called the Army of Occupation, encamps a short distance above the mouth of the Rio Grande River, opposite the Mexican town of Matamoros and 119 miles from the mouth of the Nueces.

The Mexican forces at Matamoros immediately commence the erection of new batteries and the American force begins a fort.

April 10 Colonel Truman Cross, assistant quartermaster general in the American army, is murdered by Mexican bandits.

April 12 General Ampudia, of the Mexican forces at Matamoros, serves notice upon General Taylor either to withdraw within twenty-four hours and return to the Nueces out of the disputed territory, or else accept war. General Taylor replies that his orders are for him to remain here until the boundary dispute is settled. He announced a blockade of the Rio Grande River.

April 19 Second Lieutenant Theodoric Henry Porter, Fourth Infantry, is killed in action with Mexican guerillas.

April 25, this 1846, occurs the first battle of the war, when at La Rosia a squadron of sixty-three Second Dragoons under Captain Seth B. Thornton, reconnoitering up the Rio Grande River, is surrounded by 500 Mexican regular cavalry. Second Lieutenant George T. Mason and eight enlisted men are killed, two men wounded, Captain Thornton, two other officers and forty-six men are captured.

By this victory the Mexicans are much elated; the flame of war is lighted in the United States.

May 11 President Polk announces a state of war, and a bloody invasion of American soil by the Mexican forces that had crossed the Rio Grande.

May 13 Congress passes a bill authorizing men and money with which to carry on the war, and declaring that the war has been begun by Mexico. There were objections to the bill on the ground that the President had ordered troops into the disputed territory without having consulted Congress, and that war might have been avoided. But all parties agree that now they must support the Flag.

General Taylor calls on the governors of Louisiana and Texas for 5000 volunteers.

April 28 Captain Samuel Walker and some seventy Texas Rangers and Volunteers are attacked and beaten by 1500 Mexican soldiers near Point Isabel, the American base of supplies. Captain Walker and six men make their way to General Taylor with report that his line of communication has been cut.

May 1, having almost completed the fort opposite Matamoros above the mouth of the Rio Grande, General Taylor leaves a garrison of 1000 men and marches in haste to rescue his supplies at Point Isabel. The Mexican troops are appearing in great numbers, and matters look serious for the little American army.

May 3 the Mexican forces at Matamoros open fire upon the fort, thinking that General Taylor has retreated.

May 8 General Taylor, hurrying back to the relief of the fort, with his 2300 men defeats 6500 Mexicans under General Arista in the artillery battle of Palo Alto or Tall Timber, fought amidst the thickets and prairie grasses about sixteen miles from Point Isabel. American loss, four killed, forty wounded; Mexican loss, more than 100 in killed alone.

The next day, May 9, “Old Rough and Ready” again defeats General Arista in the battle of Resaca de la Palma, or Palm Draw (Ravine), a short distance from Palo Alto. Having withstood a fierce bombardment of seven days the fort, soon named Fort Brown, of present Brownsville, Texas, is safe. The Mexican forces all flee wildly across the Rio Grande River.

May 18 General Taylor throws his army across the river by help of one barge, and occupies Matamoros. Here he awaits supplies and troops.

August 20 he begins his advance into Mexico for the capture of the city of Monterey, 150 miles from the Rio Grande River and 800 miles from the City of Mexico.

Meanwhile General Paredes, president of Mexico, has been deposed by another revolution, and General Santa Anna has been called back.

September 21–22–23 General Taylor with his 6600 men assaults the fortified city Monterey, in the Sierra Madre Mountains of northeastern Mexico, and defended by 10,000 Mexican soldiers under General Ampudia.

September 24 the city is surrendered. American loss, 120 officers and men killed, 368 wounded; Mexican loss, more than 1000.

General Taylor proceeds to occupy northeastern Mexico. In November he receives orders to detach 4000 men, half of whom shall be Regulars, for the reinforcement of General Scott’s expedition against Vera Cruz.

February 22, 1847, with 4300 Volunteers and 450 Regulars he encounters the full army of General Santa Anna, 20,000 men, at the narrow mountain pass of Buena Vista, near Saltillo seventy-five miles southwest of Monterey.

The American army, holding the pass, awaits the attack. In the terrible battle begun in the afternoon of February 22 and waged all day February 23, the Mexican troops are repulsed; and by the morning of February 24 they have retreated from the field. American loss, 267 killed, 456 wounded, 23 missing; Mexican loss, 2000.

The battle of Buena Vista leaves the American forces in possession of northeastern Mexico. General Santa Anna now hastens to confront General Scott and save the City of Mexico. General Taylor returns to Louisiana, and there is no further need for his services in the field.
