When Russia declared war on the Ottoman Empire in April 1877, it was the fifth time during the nineteenth century that hostilities had broken out between the two empires.The war was to be fought in two distinct theatres. In Europe, as on previous occasions, the Russian objective was to cross first the Danube and then the formidable Balkan Mountains before striking for Constantinople. In Asia, over territory also contested many times before, the Russians aimed to seize Kars and then Erzerum.At first all went well for the invaders, the Turks making no serious attempt to hold the line of the Danube, while a thrust south by General Gourko succeeded in crossing the Balkans. In Asia, a er initial success the Russian advance was halted by defeat at Zevin. In Asia, the Turks suffered a major defeat in the battle of Gods Mountain, and were driven back to Erzerum, while Kars fell to a brilliant assault by the Russian forces. These defeats marked the beginning of the end for the Turks. By January 1878 the Russians were over the Balkans in force, and the last viable Turkish army was surrounded and captured at Shenovo.The authors detailed text is accompanied by an extensive number of black and white illustrations, an impressive colour plate section, plus black and white and colour battle maps.
