During the days the American Civil War the Union Generals kept President Lincoln abreast of progress via wire telegraph. In order to accomplish this a team had to move the wire every time the general moved.
Information sent to the general – troop movement, numbers, locations, supply line, equipment – didn’t arrive by wire. It came in Morse code from individuals stationed on hills or rooftops armed with a flag attached to a four-foot hickory stick. It was called a Wig Wag Flag.
Messages began with the flag held in an overhead vertical position. Dropping the flag to a horizontal position on the sender’s right side made a DIT (dot). Dropping it to a horizontal position left side was a DAH (dash). Held in vertical position signified the beginning or end of a letter. Straight down meant the end of a word or finished.
vertical up meant the beginning of a letter
