A speculative forecast of a large-scale European war describes a chain of diplomatic crises, mobilisations and coordinated campaigns that spread from the Balkans across Central Europe and into colonial and naval theatres. Episodes include an attempted assassination, declarations of war, manoeuvres and pitched battles between Russia, Germany, France, Austria, Italy and Britain, combined naval engagements, landings, sieges and distant operations in Asia and Africa. The work interleaves battlefield reportage, strategic councils and political reactions at home, and concludes with reflections on imperial defence and the war's general effects, accompanied by illustrative sketches and appendix interviews on defence policy.
