The Agony of Belgium The Invasion of Belgium in WWI August-December 1914. A contemporary account of the German Invasion of Belgium when Fox was the War Correspondent for the Morning Post, which alerted the world to atrocities visited on the civilian population, and to historic buildings.This is a rare chance to re-discover a contemporary account of a military conflict which took place a Century ago. The Agony of Belgium, written in 1914 by Frank Fox, a war correspondent veteran of the Balkan Wars, precedes the trench warfare of the Great War. It recounts events that the modern European mind would probably wish to forget. The bravery and resilience of the relatively new and untested Belgian Army, following the rejection of the German Ultimatum by the King, deserves a wider audience.
