General History/World War I and communications

Field telephones worked by cables and so were vulnerable to disruption by shell fire. The Germans listened in the British communications. The Fullerphone (1915) was a small Morse Code transmitter/receiver but also needed cables. Lamps and flags were used for Morse and Semaphore, sometimes just flag waving. Flares were used, different colours representing pre-arranged commands. Runners were best for detailed requests and/or orders.

I have a long and intense interest in European and World History. This also includes Military History - especially as I have been a military physician-surgeon for 15 years. I`m also interested in the history of Science, Technology-Engineering, Medicine and Mathematics.


A life long intense interest. But I'm not a professional historian - though the next best thing, an educated VERY interested amateur!

I'm a Doctor of Medicine, specialist in Medical Oncology, Radiation Therapy and Radiation Protection. But that has no connection to this.
However I do answer such questions too here on and have done so for a long time. For such questions click on the appropriate link: Oncology (General Cancer), Military History, Brain Tumors, Breast Cancer, Colon Cancer
