The war slowed down because defensive strategies were more successful, leading to trench warfare. In many conflicts, particularly in World War I, the implementation of effective defensive tactics, along with the development of fortified positions, led to a stalemate. This resulted in prolonged periods of trench warfare, where neither side could gain a significant advantage, slowing down the overall pace and progression of the conflict.
