What is Semaphore? • Semaphore is a method of visual signaling. It is most commonly done by the use of flags but can also be done with lights. Before the invention of the telegraph, signaling from high towers was used to transmit messages between distant points. In the Navy it is used to signal between ships by sailors manipulating flags to indicate the different letters of the alphabet.
The Semaphore Flag The flags are usually square, red and white, divided diagonally with the red portion in the upper hoist.
