A COMPREHENSIVE OVERVIEW OF THE TROOPS INVOLVED IN THE FIRST WORLD WAR CAMPAIGNS IN SOUTHEASTERN EUROPE. It was events in the Balkans which sparked off the Great War, with the assassination of the Austrian heir Prince Franz Ferdinand in Sarajevo, and the consequent invasion of Serbia by Austro-Hungarian armies on 2 August 1914. Nevertheless, the subsequent four-year war in that theatre is always overshadowed by the simultaneous campaigns on the Western Front. For the first time this book offers a concise account of these complex campaigns, the organisation, orders of battle, and the uniforms and insignia of the armies involved: Austro-Hungarian, German, Ottoman, Serbian, Montenegrin, Albanian, British, French, Italian, Russian, Bulgarian, Greek and Rumanian.
