2What 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.
3The Semaphore Flag
The flags are usually square, red and white,
divided diagonally with the red portion in the
upper hoist.
