Soon, Allen's health began to fail, and he decided to leave Houston, signing over to his wife, whom he had never divorced, most of what remained of his many enterprises. Augustus Allen relocated to
Mexico to tend to his health and a new start in life. In 1852, Augustus was appointed United States consul for the port of
Tehuantepec on the Pacific Ocean, and in 1858, he was given the same position for the port of Minotitlán. These offices gave him control of the consular affairs of the United States for the entire
Isthmus of Tehuantepec, a commercially important position. In partnership with an Englishman named Welsh, Allen developed an extensive private shipping business. He was never able to recover his health, however, and realized, in 1864, that he was critically ill. Augustus then closed his business and went to Washington, D.C., to resign his consulships. Soon after arriving there, he contracted
pneumonia, and died on Monday, January 11, 1864, aged 58 in Washington, D.C., and was buried in the
Green-Wood Cemetery in
Brooklyn, New York. Several Houston landmarks, including
Allen Parkway and Allen Center, as well as
Allen's Landing Park, commemorate Augustus and his brother, the city's two founders.
