World War 1 Spies- Espionage
Transcript of World War 1 Spies- Espionage
Espionage Spies could get information about
their enemies secretly and could
pass information secretly Why were spies so
important in WW1? 1. A famous spy Mata Hari Most famous: What were some gadgets
used by spies? Homing Pigeons- Used to carry messages Sabotage by Enemy agents Horses were infected with anthrax
Blew up military installations, Invisible Ink + Mix lemon juice with potassium and write on paper with the solution. To read what the invisible note says, hold the paper to a light source and the message will appear Even human bodies were used for recording secret messages To get the messages off, rub in citrus Ways messages
were hidden *in tins
*in packets of chocolate
*in bars of soap
*sewn into clothes Mata Hari- most famous spy (AND female) of WW1 At start of war, spied for Germany
By 1916, was double agent for Germany and France
Had relationships with many high-ranking men in influential positions
Her relationships and connections took her across international borders- helping with her spying
Arrested by Germans on February 13th, 1917 in Paris
Tried by military court and sentenced to death for spying
Shot on October 15th, 1917 when she was 41
3. MI5- What is/was it? How did it contribute to WW1? The MI5 was the spy organization of Britain. It's purpose: protect Britain's national security VERY successful
•The spies were well-trained
•Not about how many other spies they caught, but how many secrets they uncovered Its founder:
Vernon Kell Kell Several female recruits held high positions in the MI5- start of more women's rights and jobs 4. Making Codes 5. Breaking Codes Helped keep messages secret
so enemies would not
discover secret plans Codes were used to write the Zimmermann Telegram
Germans sent it to Mexico and was intercepted by the British who broke its code The SMS Magdeburg German ship
Hit sand bank and Russian torpedo boat took over
Discovered naval codebook
Russians so inexperienced could not break code
Another codebook was captured on the Hobart which had keys for a superencipherment system
Helped Russians read the German naval messages ***Superencipherment- to encode a message that is already a cryptogram (a text written in code) To make a code, letters, numbers, or symbols replace different words/letters of a signal or message For example:
Morse Code . -.. - - . . - - - - - -. -
Can you guess what this says? Breaking codes can be really hard
One man took 16 years figuring out a code to decipher a message Cryptanalysts are people who break codes
"E" is used most often in English- so whichever symbol appears the most is probably the letter "E"
Look for two letter words ending in "E"- there are only four in English
Look for symbols on their own- only two in English- "I" and "A" Machines used to decipher codes Bombe Types of ciphers Simple Cipher Cipher Disk The two inside rings are rotated to align with numbers and letters in two outside rings.
This makes a simple substitution cipher in which one letter stands for another (This type of cipher is easy to break)
ex.) "W" stands for "E" Hey, I'm James Bond
