From the Annals of the Tejanos – In 1842, Juan Seguín resigned as Mayor of San Antonio due to threats on his life. He was falsely accused of aiding the Mexican army and discrimination against Texans of Mexican origin – even those who served in the revolution – became too oppressive. He fled to Mexico to “seek refuge amongst my enemies,” where he was captured, arrested and coerced to enlist in the Mexican army as a staff officer. He returned to San Antonio with the opposition army of Adrian Woll in September 1842 and in a cruel twist of fate later served under Santa Anna in the Mexican-American War of 1846–1848.
In February 1848, Seguín requested permission to return to Texas and eventually established a home adjacent to his father’s house and began ranching in Floresville. He also returned to political life and was elected to two terms as Justice of the Peace of Bexar County and later County Judge of Wilson County. In 1883 he settled in Nuevo Laredo, Tamaulipas to be near his son Santiago, who was mayor. He died there on August 27, 1890. His remains were returned to Texas in 1974 and as part of the nation’s Bicentennial celebration were reinterred in Seguin during ceremonies on July 4, 1976.
