Technology is an amazing thing. Perhaps more amazing is the way we take it for granted. We gripe all too quickly when it doesn’t work, but how often do we think about how fascinating it is to be able to click a mouse and have something happen on the screen, all communicated by…well, I don’t even know!
During the Civil War, communication depended on couriers (who could be shot) or the telegraph (whose wires could be cut). There was no WiFi. There were no radio signals. If the courier was killed, the orders never got there, and fighting units ended up stranded.
Before the war, Albert Myer and E.P. Alexander developed a communication system that could be used by an army when the distances were too great for a courier on horseback. It was a 19th Century cell phone: fully mobile, it could travel with the army and did not require setting up a landline (telegraph wires). Encryption was necessary though–at the war’s start, Alexander when South and Myers went North, which meant both sides had the technology and could read the messages!
What was this new-fangled tech, you ask? The Signal Corps or “wig-wag” system. A typical station involved three men: one to use a flag to send coded messages, one to read incoming messages, and one to write it all down. The system used a series of numbers. A dip of the flag to the left was a 1, a dip to the right was a 2, and a dip straight in front was a 3. “3” was used to signal the end of a word (3), sentence (33), or message (333). “1” and “2” were used in combinations to represent letters or words.
- “1 3 12 33 11222 3 111 333” = “Advance artillery. Resume attack.” (using set phrases)
- “Jump.” = 2211 [J] 221 [U] 2112 [M] 2121 [P] 333 [end of message]. (spelling it out)
Stations could be set up miles from each other, thanks to telescopes, and they could work at night, using torches instead of flags. The system worked quite well. Except for the weakest part: the humans.
Sending messages only worked if the crew on the receiving end noticed the continuous wig-wagging meant to get their attention. On July 3, 1863, a signal station on a mountain miles away from Gettysburg noticed the Confederates moving an awful lot of cannons into position along Seminary Ridge. Frantically, the station signaled to its relay with the Union army. They were never noticed, so their warning was never delivered!
Fortunately for the Union army, the ensuing smoke caused the Confederate artillery to overshoot, inflicting less damage than intended and allowing for a Union repulse of Pickett’s Charge. As it turned out, the breakdown in communication technology did not end in the Union army’s destruction. But I imagine there was a soldier cussing out his limited technology!
Some things never change.


It’s been said that a good book (or any work of art) leaves you with questions, wanting to know more. Today, I was working on assembling cats in small domes to sell in our gift shop. They’re all cute, and sometimes it’s hard to part with them because they turned out so well, but this time there was a husband and wife set that Ruth made that struck me the first time I saw them, and has continued to make me pause every time I look at them.
Today is the 153rd anniversary of the first time the men of the 54th Massachusetts Volunteer Infantry saw combat. In two days, we will reach the 153rd anniversary of their second fight: the assault on Battery Wagner. It was there that the men of the 54th proved that they could fight . . . by losing nearly half of the men who went into battle.
The regimental color-bearer, John Wall, fell, but Sgt. William H. Carney picked up the flag. He knelt on the wall with the colors until the regiment fell back. By the time he reached the hospital, Sgt. Carney had been wounded in the head, breast, arm, and both legs. He simply told the men in the hospital, “I but did my duty. The dear old flag never touched the ground.” For his courage, Sgt. Carney received the Congressional Medal of Honor in 1900. His was the earliest action for which the Medal of Honor was awarded to a black soldier.
