Final answer:
The Battle of Verdun was intended to annihilate as many French troops as possible, resulting in over a million casualties without significant territorial gain.
Step-by-step explanation:
The battle designed to annihilate as many French troops as possible was the Battle of Verdun. During the World War I in February 1916, the Germans, under the command of General Erich von Falkenhayn, intended this battle to 'bleed France white' by forcing the French to defend a historically significant fortress city. The battle resulted in an enormous number of casualties on both sides, with over a million men killed or injured, and it raged for several months without significant territorial gains for the Germans or the French.
