In thus assembling, we commune in the sacrament of a common memory with our comrades across the seas, who on all their homestead hills are celebrating the same glorious event. With them we exult in the proud consciousness that by doing our duty as American soldiers in the days of our youth, we not only gave renewed lustre to the martial annals of our country, but through the triumph of our arms we added greatly to the sum of human happiness, by widening the area of the world’s civilization. The occasion permits me to glance but briefly at the events of that war which to some are still vivid memories, while others must either glean them from the historic page or hear them recited by the men who then acted history. That war had its origin in the invasion of the soil of the United States by the Army of Mexico. On January 10th, 1845, the Congress of the United States passed an Act providing for the annexation of Texas. The Act was ratified by the Congress of that Republic on July 4th, 1845, and Texas with its two hundred and sixty five thousand square miles of territory, an area greater than that of the German Empire or of Austria, thus became an integral part of the American Union. Texas had already maintained her independence for ten years against Mexico, the parent country. Those who have questioned the political morality of the act of annexation may be fully answered by reference to the fact that England, France and Spain had all formally recognized the independence of the Republic of Texas three years before her admission into our Union. Mexico resolved to nullify that act by force of arms. In view of her aggressive attitude, Major General Zachary Taylor, U. S. Army, was ordered to the Rio Grande, the Western boundary of Texas, with a force of about four thousand men, chiefly regulars, where he arrived July 20th, 1845, establishing his headquarters at Corpus Christi, within four miles of the Mexican Army, then encamped ten thousand strong, under the command of General Ampudia, on the South side of that river. In January, 1846, General Taylor moved his command to a point opposite Matamoras, Mexico, and erected an earthwork which he termed Fort Brown.
