Previously a largely rural area, East Texas became more urban as workers were recruited for the oil, shipbuilding, and aircraft industries. East Texans made many contributions to the war effort, both at home and in the armed forces. High schools had patriotic programs as well, but so many teachers and older students left for the military or for defense jobs that budgets were cut, programs dropped, and the curriculum had to be scaled down. Hospitals reported a shortage of supplies and medical personnel, as many doctors and most of the younger nurses joined the services.
