Question: The Long Expedition was an 1819 attempt to take control of Spanish Texas by filibusters, led by James Long who was accompanied by which 19th-century American pioneer, who played a prominent role in the Texas Revolution, culminating in his death at the Battle of the Alamo?
Context: The 2014 Texas Revolution season was the team's fifteenth season as a professional indoor football franchise, fifth in the Indoor Football League (IFL), and second as the "Texas Revolution".  One of nine teams in the IFL for the 2014 season, the Texas Revolution competed in the United Conference for the second consecutive year.  The team played their home games at the Allen Event Center in Allen, Texas.  Chris Williams returned to the IFL as the Texas Revolution's director of football operations and head coach for 2014.  The team started strong but faltered, compiling a 3–11 record and missing the playoffs.  In the post-season, Williams resigned and the team announced their departure from the IFL. The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event in the Texas Revolution.  Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna launched an assault on the Alamo Mission near San Antonio de Béxar (modern-day San Antonio, Texas, United States), killing all of the Texian defenders.  Santa Anna's cruelty during the battle inspired many Texians—both Texas settlers and adventurers from the United States—to join the Texian Army.  Buoyed by a desire for revenge, the Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the revolution. James "Jim" Bowie (pronounced ) (  1796 – March 6, 1836) was a 19th-century American pioneer, who played a prominent role in the Texas Revolution, culminating in his death at the Battle of the Alamo.  Stories of him as a fighter and frontiersman, both real and fictitious, have made him a legendary figure in Texas history and a folk hero of American culture. William Barret "Buck" Travis (August 1, 1809 – March 6, 1836) was a 19th-century American lawyer and soldier.  At the age of 26, he was a lieutenant colonel in the Texas Army.  He died at the Battle of the Alamo during the Texas Revolution.  Travis County and Travis Park were named after him for being the commander of the Republic of Texas at the Battle of the Alamo. James Clinton Neill (c. 17881848) was a 19th-century American soldier and politician, most noted for his role in the Texas Revolution and the early defense of the Alamo.  He was born in North Carolina. James Butler Bonham (February 20, 1807 – March 6, 1836) was a 19th-century American soldier who died at the Battle of the Alamo during the Texas Revolution.  He was a second cousin of William B. Travis and was a messenger of the Battle of the Alamo.  His younger brother, Milledge Luke Bonham, was a brigadier general in the Confederate States Army in the American Civil War, and served as Governor of South Carolina from 1862 to 1864. The Adams–Onís Treaty of 1819, also known as the Transcontinental Treaty, the Florida Purchase Treaty, or the Florida Treaty, was a treaty between the United States and Spain in 1819 that ceded Florida to the U.S. and defined the boundary between the U.S. and New Spain.  It settled a standing border dispute between the two countries and was considered a triumph of American diplomacy.  It came in the midst of increasing tensions related to Spain's territorial boundaries in North America against the United States and Great Britain in the aftermath of the American Revolution; and also during the Latin American Wars of Independence.  Florida had become a burden to Spain, which could not afford to send settlers or garrisons.  Madrid decided to cede the territory to the United States through the Adams–Onís Treaty in exchange for settling the boundary dispute along the Sabine River in Spanish Texas.  The treaty established the boundary of U.S. territory and claims through the Rocky Mountains and west to the Pacific Ocean, in exchange for the U.S. paying residents' claims against the Spanish government up to a total of $5,000,000 and relinquishing the US claims on parts of Spanish Texas west of the Sabine River and other Spanish areas, under the terms of the Louisiana Purchase. Ángel Navarro (1748–1808) was a leading early Spanish settler and patriarch of San Antonio, Texas.  The Navarro family played a prominent role in the Mexican and Texas revolutions.  He was born in Corsica in 1748 and settled in Spanish Texas in 1769.  Navarro was the seventy-second alcalde (mayor) of San Antonio under Spanish Texas. The Long Expedition was an 1819 attempt to take control of Spanish Texas by filibusters.  It was led by James Long who was accompanied by Jean LaFitte, James Bowie, and Ben Milam.  Long's army successfully established a small independent republic government, known as the "Republic of Texas" being the first use of the sovereign name and also called the Long Republic (distinct from the later Republic of Texas created by the Texas Revolution).  The expedition crumbled later in the year, as Spanish troops drove the invaders out.  Long returned to Texas in 1820 and attempted to reestablish his control. The Battle of Coleto, also known as the Battle of Coleto Creek, the Battle of the Prairie, and the Batalla del encinal del Perdido, was fought on March 19–20, 1836, during the Goliad campaign of the Texas Revolution.  In February, General José de Urrea led a branch of the Mexican army up the Gulf Coast of Mexican Texas toward Goliad, where a large contingent of soldiers from the Texian Army were garrisoned under Colonel James W. Fannin.  Simultaneously, Mexican president Antonio Lopez de Santa Anna led a larger force into the Texian interior, where on March 6 his troops won the Battle of the Alamo.  After learning of the Alamo's defeat, Texian general Sam Houston ordered Fannin to retreat from Goliad and join the rest of the army in Victoria.
