it was the cause of the battle of the somme which was the bloodiest first day in British history, the battle of verdun was going badly for the allies so Haig decided to divert the Gemans and releive the pressure on verdun, which it did but created lot of casulaties on the first day, the worst in history
The battle of Verdun was simply a German derived strategy to bleed the French army dry. Attrition, attrition, attrition. The German leadership knew that the French would never break at Verdun so more and more troops were fed into the meat grinder. Of course German losses were horrendous too.
