Which of the following events inspired Gutierrez de Lara's mission, first in the United States and then in Texas?

GUTIÉRREZ DE LARA, JOSÉ BERNARDO MAXIMILIANO (1774–1841).José Bernardo Maximiliano Gutiérrez de Lara, Mexican revolutionary and diplomat, son of Santiago Gutiérrez de Lara and Maria Uribe, was born at Revilla (present Guerrero), Tamaulipas, Mexico, on August 20, 1774. He married his cousin María Josefa Uribe and became a merchant, blacksmith, and property owner at Revilla. During the Mexican War of Independence, led by Miguel Hidalgo y Costilla, Gutiérrez and his brother were successful in fomenting revolution in Nuevo Santander, and Gutiérrez was sent by Hidalgo to recruit along the Rio Grande. After the Casas Revolt, Gutiérrez was commissioned by the rebels to solicit aid in the United States. He left Saltillo for the United States on March 17, 1811, going by way of Revilla to collect supplies. After the capture of Hidalgo, he resolved to continue his mission and in August 1811 went to Natchitoches, Louisiana. In October he left for Washington, D.C., with letters of introduction from John Sibley and arrived on December 11, 1811. He was received by Secretary of State James Monroe, who listened to the plans for establishment of a republican government in Texas and use of Texas as a base for effecting the liberation of Mexico. During his stay in Washington the Mexican leader met the ministers of Britain, Denmark, and Russia, and visited the representative from revolutionary Venezuela. Also in Washington, Gutiérrez met José Álvarez de Toledo, and with Álvarez in Philadelphia in January 1812 made plans for the liberation of Texas and Mexico. Back in Louisiana in March 1812, Gutiérrez was introduced to William Shaler, special agent from the United States, who helped Gutiérrez to return to Texas. In April 1812 the two men were in Natchitoches, where the Gutiérrez-Magee expedition assembled and set out for Texas.
