How did the tanks finally have success and what benefits did it provide World War 1?

Tanks finally had success in World War I during the Battle of Cambrai in 1917, where they were used in large numbers to break through entrenched German defenses. Their mobility and ability to traverse difficult terrain allowed them to disrupt enemy lines and create breakthroughs that infantry and artillery could exploit. The introduction of tanks also provided a psychological advantage, as they challenged the traditional warfare tactics and instilled fear in enemy troops. Ultimately, their effectiveness marked a significant shift in warfare strategy, leading to more mobile and mechanized forms of combat in subsequent conflicts.
