I'm writing a bit of a history of Cockscomb, this is highest peak in the Groot Winterhoek, the mountain peak that is visible from Port Elizabeth & Jeffries Bay.

There is a bit of a legend about a heliograph record being set during the Anglo-Boer War, where messages were flashed by heliograph from the Cockscomb mountain to Compasberg (202km) or Nardouwsberg (148km). Apparently, the stone wall on the top of the peak is the remains of a British heliograph station.

Has anybody have any other information about this record or any ideas where to start looking for details?

Welcome to the forum Derek.

I have searched this site and found no matches for Cockcomb and only a few for Winterhoek, none of which is relevant, so I cannot add anything to your search I am sorry to say.

Hi Derek

According to the history of the Eastern Province Command Signals Unit, the record of 130 miles was claimed by Captain Sadler of the Natal Carbineers in 1911, using a 5 inch mirror from Compassberg to the Cockscomb Mountains , to Major Home.

This article gives a summary of typical distances of various methods of communication used during the Boer War.

a. Using the 10-inch reflector in ideal conditions, marching distance of over miles (160km) were recorded in both India and China.
b. Pigeons were also used, as were searchlights in conjunction with shutters, as Admiral Sir Percy Scott records in his autobiography.
c. Highly skilled operators were capable of six words per minute.

I found a chapter of interesting heliograph info in a book on Gideon Scheepers.
