=== Crimean War (1853–1856) ===
In the [[Crimean War]] various forms of [[telegraphy]] played a major role; this was a first. At the start of the campaign there was a telegraph link at Bucharest connected to London. In the winter of 1854 the French extended the telegraph link to the [[Black Sea]] coast. In April 1855 the British laid an underwater cable from Varna to the [[Crimean peninsula]] so that news of the Crimean War could reach London in a handful of hours.<ref>{{cite book | author1=Christopher Andrew |title=The Secret World: A History of Intelligence |publisher=Penguin Books Limited |year=2018 |page=ccxiii |isbn=9780241305225 }}</ref>
