Through a letter addressed to the mayor of San Antonio, he achieved the temporary imprisonment of Stephen Austin in 1834.
Miguel Falcón served in 1833 as head of state of the province of Coahuila and Texas.
During this time he wrote to the mayor of San Antonio Jose Miguel de Arciniega to imprison the American businessman and settler Stephen Austin, a resident of Texas who had proposed to the Council of San Antonio the separation of the province of Coahuila from Mexico (an emancipation in which he would collaborate).
Falcón's petition was approved and in 1834 Austin was imprisoned, entering the dungeon on February 22 of that year.
[1] Later, on July 18, 1835, Falcón was appointed governor of Texas and Coahuila, a position he held for less than a month, as on August 13 of the same year he was succeeded in the government of the province by Bartolomé de Cárcenas.
