Striking view of the Sea of Marmara, during the Russo-Turkish War.
The maps shows the area from the Dardanelles to the Bosporus and the Black Sea, including Adrianople, Bursa, Silivri, and Constantinople. This view captures a decisive moment in the 1877-1878 Russo-Turkish War. Following its success at Plevna, the Russian army had advanced to Adrianople and reached the outskirts of Constantinople. Britain responded by dispatching British war ships to the Sea of Marmara, putting pressure on Russia to ultimately abide by a treaty drawn up at a Congress of the Great Powers held in Berlin under the leadership of Otto von Bismarck.
