One of the first policy documents to discuss controlling refugee movement was issued by Headquarters, 1st Cavalry Division (Infantry), on July 23,1950 .
Movement of civilians and refugees in the 1st Cavalry Division area was permitted from 10:00 AM to 12:00 noon only;
no ox carts, trucks, or civilian cars were allowed to operate on highways;
no fields could be worked;
no schools, shops, or industries could be operated unless they were essential to the war effort;
and municipal authorities, local police, and National Police were to enforce this directive.
The National Police would collect all refugees from the countryside and highway and carry them by rail or trucks to screening points. Division Counter-Intelligence Corps (CIC) personnel, including an attached Korean CIC Team, would screen the refugees at established roadblocks and checkpoints. Units within the Division had instructions to turn over refugees to CIC or G-2 (Intelligence) Interrogation for screening. 22
