Schleicher became disillusioned with the experiment in Bettina (he is said to have remarked that "the bigger the men, the more they talked, the less they worked and the more they ate.") From 1854—1861 Schleicher was surveyor of the Bexar Land District, which included most of the area from San Antonio to
El Paso. During this time he acquired title to extensive land holdings on the
Edwards Plateau. In 1856, Schleicher married Elizabeth Tinsley Howard. Beginning in 1858, he and his brother-in-law, Heinrich Dresel, published the San Antonio German-language newspaper the
Texas Staats-Zeitung. Schleicher was a cofounder of the San Antonio Water Company in 1858 and of
Alamo College in 1860. He was elected to the
Texas Senate in 1859 representing the
31st District which comprised territory west of San Antonio: Gillespie, Medina, and Uvalde Counties. Like most German immigrants, Schleicher opposed Texas's secession from the Union. However, after his adopted state joined the
Confederacy, Schleicher became a captain in the Confederate Army, in charge of Gen.
John B. Magruder's Corps of Engineers. ==After the war and service in Congress==
