  • Compare: Lee, Bartholomew. "Radio Spies – Episodes in the Ether Wars" (PDF). Archived from the original (PDF) on 27 February 2008. Retrieved 8 October 2007. As early as 1900 in the Boer War, the Royal Navy in South Africa appears to have used wireless sets inherited from the Royal Engineers to signal from the neutral port of Lourenco Marques 'information relative to the enemy' albeit in violation of international law. [...] This first use of radio for intelligence purposes depended, of course, on the inability of others to intercept the signals, but in 1900, only the British in that part of the world had any wireless capability.
