It is widely regarded as the battle of the First World War; an enormous clash of attrition which epitomised the bloody stalemate of the war. The ten-month Battle of Verdun began 100 years ago, with German Chief of Staff General von Falkenhayn seeking to ‘bleed France white’ by launching an all-out attack on the narrow stretch of land at Verdun. Over a thousand German artillery guns fired upon the vastly inferior number of French troops – they had just 30,000 men, against 140,000 Germans – along a six-mile stretch of the French front. The battle which followed was to last for over 300 days. By looking at personal sources from Nineteenth Century Collections Online, the sheer scale of this part of the conflict is clear to see.
