In 1866 Beatty-Kingston began working for "The Daily Telegraph" as its correspondent in Vienna, afterwards moving to Berlin, and then returning to London as the paper's foreign editor. His foreign assignments for the "Telegraph" included covering six conflicts: the Austro-Prussian War in 1866; the siege of Rome a year later; the Franco-Prussian War; the Herzegovina uprising in 1875–1877; the Serbian rebellion of 1876–1878; and the Russo-Turkish War of 1877–1878. As a correspondent with the Prussian forces in 1870–71 he got on well with Bismarck and was able to obtain the terms of the capitulation of Paris much earlier than his peers on other British papers or even the British government. A fluent linguist, Beatty-Kingston contributed not only to numerous British publications, including "Macmillan's Magazine", "The Fortnightly Review", "The Graphic" and "The English Illustrated Magazine", but also continental papers such as "Die Presse" in Vienna and "Perseveranze" in Milan. He disliked gossip columns and refused to write for the society press.
