Fort Sam Houston served as the headquarters of the Fifth and Sixth United States Armies, the Army Medical Command, and a Criminal Investigation Command when the Second Great Depression began. They had the best military police, the best doctors, and commanded units deployed all over the Homeland and throughout the rest of the Americas. When Fort Sam stopped following the new President’s orders, it had a profound effect on military units throughout the Western Hemisphere. And though it suffered from the same desertions as other military bases did, it managed to maintain an operational core for all of its missions. The military police were especially effective, with most of their personnel refusing to go home, and the hulking major in charge of their special investigations group led an investigation that eventually uncovered the federal influence behind the gang, race, and drug cartel violence that washed over San Antonio. That news would have a profound effect on the future of Fort Sam and all of Texas.
