Question: Question: What state did the battle that Stanley lead an infantry division for the Army of the Mississippi take place? Passage:He fought at several battles in Missouri, including the Battle of Wilson's Creek, where he guarded the supply trains. President Abraham Lincoln appointed Stanley as brigadier general September 28, 1861, although the U.S. Senate did not confirm the appointment until March 7, 1862. Fighting in the Western Theater, he participated in the operations against New Madrid, Missouri and the Battle of Island Number Ten. He was involved in numerous major battles, including the Second Battle of Corinth, where he commanded a division of infantry of the Army of the Mississippi, and the Battle of Stones River, in which he led the cavalry of the Army of the Cumberland. On March 11, 1863, Stanley was appointed major general to rank from November 29, 1862. Stanley also led the Union cavalry in the Tullahoma Campaign. He fell ill late in 1863 and missed the Battle of Chickamauga. In 1864, he fought under William Tecumseh Sherman as a division commander in the IV Corps of the Army of the Cumberland during the Atlanta Campaign, and he was promoted to command of the corps when Maj. Gen. Oliver O. Howard was named commander of the Army of the Tennessee. After the capture of the city, instead of employing him marching to the sea, Sherman dispatched Stanley and his IV Corps to Tennessee to help protect the state from invasion by John Bell Hood's Army of Tennessee.

Question: Question: How long was the reign of the pharaoh who used 11,000 mercenaries during his battles? Passage:An early recorded use of foreign auxiliaries dates back to Ancient Egypt, the thirteenth century BC, when Pharaoh Ramesses II used 11,000 mercenaries during his battles. A long established foreign corps in the Egyptian forces were the Medjaya generic term given to tribal scouts and light infantry recruited from Nubia serving from the late period of the Old Kingdom through that of the New Kingdom. Other warriors recruited from outside the borders of Egypt included Libyan, Syrian and Canaanite contingents under the New Kingdom and Sherdens from Sardinia who appear in their distinctive horned helmets on wall paintings as body guards for Ramesses II. Celtic mercenaries were greatly employed in the Greek world (leading to the sack of Delphi and the Celtic settlement of Galatia). The Greek rulers of Ptolemaic Egypt, too, used Celtic mercenaries. Carthage was unique for relying primarily on mercenaries to fight its wars, particularly Gaul and Spanish mercenaries.
