註釋The world's great economic powers aligned into two opposing forces in World War I. Although still in its infancy by modern standards at the onset of the conflict, intelligence gathering and espionage would ultimately tip the balance. Readers learn how new technology exploded and resulted in developments in cryptography and surveillance as both sides raced to crack the codes and win the war.
