This exhibit showcases how the Revolutionary Army leveraged cryptology during the war. America's independence was achieved with the help of codes, ciphers, invisible ink, visual communications, and hidden messages. These techniques, practiced by the colonists and the British, protected communications vital to the commanders. They disguised information needed to plan strategy, report the enemy's capabilities, and provide warnings. Solving and reading the enemy's secret messages also proved critical. Not only did it reveal the enemy's intentions, but a few even revealed American traitors.
