which world war 1 military tactic resulted in a prolonged stalemate
Trench warfare Throughout World War I, the major combatants slowly developed different ways of breaking the stalemate of trench warfare; the Germans focused more on new tactics while the British and French focused on tanks.
First Battle of the Marne The battle of the Marne was a major turning point of World War I. By the end of August 1914, the whole Allied army on the Western Front had been forced into a general retreat back towards Paris. Meanwhile, the two main German armies continued through France. It seemed that Paris would be taken as both the French and the British fell back towards the Marne River. The war became a stalemate when the Allied Powers won the Battle of the Marne. It was the first major clash on the Western Front and one of the most important single events in the entire war. The German retreat left the Schlieffen Plan in ruins and Germany had no hope of a quick victory in France. Its army was left to fight a long war on two fronts.
