On December 7, 1941, the Imperial Japanese Navy Air Service attacked Pearl Harbor on a Sunday morning, initiating the United States’ formal entry into World War II the next day.
According to the 1942 Cheltenham High School “El Delator” yearbook, Cheltenham High went on the defensive:
“Two months after the opening of school, the country was suddenly hurled into world conflict. War had finally come, and Cheltenham immediately began preparing for the worst. Air raid drills were worked out by the Defense Committee and proved successful. Big emergency water cans, red sandboxes and lanterns appeared in the halls. Windows were taped, while pickaxes, crowbars, and other implements were placed in handy spots. The first trial blackout came and turned out successfully. War had come…Cheltenham was ready.”
