Answer:
After leaving office, Houston returned to his home in Galveston. He later settled in Huntsville, Texas, where he lived in a structure known as the Steamboat House. In the midst of the Civil War, Houston was shunned by many Texas leaders, though he continued to correspond with Confederate officer Ashbel Smith and Texas governor Francis Lubbock. His son, Sam Houston, Jr., served in the Confederate army during the Civil War, but returned home after being wounded at the Battle of Shiloh. Houston's health suffered a precipitous decline in April 1863, and he died on July 26, 1863, at 70 years of age. He died due to health issues.
