Sam Houston was basically a legend, regarding his careers in being the seventh administrator of Tennessee and Texas, president of a public, a senator, a commander-in-chief, attorney, congressman, farmer, soldier, and teacher. Houston sadly took his last breath due to complexity generated by pneumonia on the date of July 26, 1863 at 6:15 pm (the described time). Pneumonia is a condition that agitates the air sacs of a lung or either the pair that creates them to fill up with liquid.
