Granville o haller

Granville Owen Haller (January 31, 1819 – May 2, 1897) was a noted Indian fighter and United States Army military officer, as well as a wealthy postbellum businessman in the Seattle, Washington, area. During the American Civil War, he was charged with the defense of south-central Pennsylvania during the early days of Gettysburg Campaign prior to the arrival of the Army of the Potomac. Haller was born and raised in York, Pennsylvania. After Haller graduated in 1838 from the York County Academy, the board of trustees recommended him for an appointment to the United States Military Academy. Not receiving Senator James Buchanan's appointment to West Point (it going instead to future Civil War general William B. Franklin), Haller responded to a summons to go to Washington, D.C., where he was commissioned as a lieutenant in the U.S. 4th Infantry Regiment. He fought Seminole Indians in Florida in 1840–1841 and later served with distinction at Monterrey, Veracruz, and other battles during the Mexican-American War, officering in the same regiment as Ulysses S. Grant. He distinguished himself in the Battle of Churubusco, where he took a key part in the assault on Molino del Rey.

Wikipedia article

The Mexican–American War, also known as the Mexican War, the U.S.–Mexican War or the Invasion of Mexico, was an armed conflict between the United States and the Centralist Republic of Mexico from 1846 to 1848. It followed in the wake of the 1845 U.S. annexation of Texas, which Mexico considered part of its territory, despite the 1836 Texas Revolution. Combat operations lasted a year and a half, from the spring of 1846 to the fall of 1847. American forces quickly occupied New Mexico and California, then invaded parts of Northeastern Mexico and Northwest Mexico; meanwhile, the Pacific Squadron conducted a blockade, and took control of several garrisons on the Pacific coast further south in Baja California. Another American army captured Mexico City, and the war ended in a victory for the United States. The Treaty of Guadalupe Hidalgo specified the major consequence of the war: the forced Mexican Cession of the territories of Alta California and New Mexico to the United States in exchange for $15 million. In addition, the United States assumed $3.25 million of debt owed by the Mexican government to U.S. citizens.
