the outbreak of the Mexican War of Independence, New Spain sought a different relationship with the Spanish crown. Some Anglo Americans fought on the side of Mexico against Spain in filibustering expeditions. One of these, the Gutiérrez–Magee Expedition (also known as the Republican Army of the North) consisted of a group of about 130 Anglo Americans under the leadership of Bernardo Gutiérrez de Lara. Gutiérrez de Lara initiated Mexico's secession from Spain with efforts contributed by Augustus Magee. Bolstered by new recruits, and led by Samuel Kemper (who succeeded Magee after his death in battle in 1813), the expedition gained a series of victories against soldiers led by the Spanish governor, Manuel María de Salcedo. Their victory at the Battle of Rosillo Creek convinced Salcedo to surrender on April 1, 1813; he was executed two days later. On April 6, 1813, the victorious Republican Army of the North drafted a constitution and declared the independent Republic of Texas, with Gutiérrez as its president. Soon disillusioned with the Mexican leadership, the Anglo Americans under Kemper returned to the United States. The ephemeral Republic of Texas came to an end on August 18, 1813, with the Battle of Medina, where the Spanish Army crushed the Republican Army of the North. The harsh reprisals against the Texas rebels created a deep distrust of the Royal Spanish authorities, and veterans of the Battle of Medina later became leaders of the Texas Revolution and signatories of the Texas Declaration of Independence from Mexico 20 years later. After the failure of the expedition, there would be no serious push for a "Republic of Texas" for another six years, until 1819, when Virginian filibuster James Long invaded Spanish Texas in an attempt to liberate the region. Eli Harris led 120 men across the Sabine River to Nacogdoches. Long followed two weeks later with an additional 75 men. On June 22, the combined force declared a new government, with Long as president and a 21-member Supreme Council. The following day, they issued a declaration of independence, modeled on the United States Declaration of Independence. The document cited several grievances, including "Spanish rapacity" and "odious tyranny" and promised religious freedom, freedom of the press, and free trade. The council also allocated 10 square miles of land to each member of the expedition, and authorized the sale of additional land to raise cash for the fledgling government. Within a month,
