How did the Germans try to break the Stalemate?

During World War I, the Germans attempted to break the stalemate on the Western Front through several strategies, including the introduction of unrestricted submarine warfare, which aimed to cut off supplies to Britain. They also launched the Spring Offensive in 1918, a series of attacks intended to exploit weak points in Allied lines using tactics like infiltration and stormtrooper units. Additionally, the use of new technologies, such as tanks and chemical weapons, was employed to gain an advantage over entrenched positions. However, these efforts ultimately failed to secure a decisive victory.
