the southern theater to include the Battle of New Orleans with General Andrew Jackson. This gives the regiment campaign credit for the War of 1812. First Indian War period The 2nd Infantry was consolidated May–October 1815 with the 3rd and 7th Infantry (both constituted 12 April 1808), and 44th Infantry (constituted 29 January 1813) to form the 1st Infantry Regiment. In the ensuing years the regiment was primarily concerned with Indian conflicts and the 1st was involved in the Black Hawk War of 1832 and the Second Seminole War from 1839 to 1842. During this time the regiment was commanded by many, now famous commanders including, Colonel Zachary Taylor, who would later become the 12th President of the United States and Second Lieutenant Jefferson Davis, who would become the President of the Confederate States in the American Civil War. War with Mexico When War broke out with Mexico in 1846, the 1st Infantry Regiment was sent across the border with General Zachary Taylor's Army and participated in the storming of Monterrey where the regiment fought house to house in savage hand-to-hand combat. From Monterrey, the regiment was transferred to General Winfield Scott's command and participated in the first modern amphibious landing in American history at Vera Cruz in 1847. Second Indian War period Following the Mexican–American War, the regiment campaigned in the Texas area against the Comanches until the outbreak of the Civil War in 1861. Civil War After escaping from rebel forces in Texas the regiment returned to the Mid-west and fought in the Mississippi area of operations. The regiment fought in one of the first battles of the Civil War at Wilson's Creek, Missouri, in August 1861. The 1st Infantry then campaigned with General Grant against Vicksburg in 1863. The end of the war found the regiment occupying New Orleans, Louisiana. Third Indian War period After the Civil War the regiment was sent West to fight the Indians once again. The 1st Infantry was consolidated in April 1869 with the 43d Infantry Regiment, Veteran Reserve Corps (constituted 21 September 1865) and consolidated unit designated as the 1st Infantry Regiment. 1st Infantry Regiment campaigned against the Sioux in the 1870s and 1890s and against the Apache, led by Geronimo, from 1882 to 1886. One member of the regiment was awarded the Medal of Honor for service during this period: 1st Lt. Marion P. Maus, 11 January 1886, Sierra Madre
