I think that one of the biggest innovations during the victory at Vimy Ridge would be the tunnel. I think the Tunnels had the biggest impact because the troops could move around no mans land unnoticed and safely. The soldiers could bring supplies up in the middle of no mans land to help the soldiers when they needed ammo or food in order to claim victory at Vimy Ridge. The Canadian troops set up the endings of tunnels close to the Germans trenches so that they could do a surprise attack on the Germans. I believe that without the tunnels the outcome of Vimy Ridge would have been different. Without the tunnels their attacks would have been different and they would not have been able to do surprise attacks on the German troops in their trenches. I think that a lot more lives would have been lost if not for the tunnels because the Canadian troops would not have the protection and safety as they did in the tunnels under no mans land. They would also use the tunnels to dig close to the enemy trenches and then place mines nearby. The mines would go off and would kill and injure the German troops. And that is why I think that the tunnels were one of the biggest reasons for the Canadians success during the victory at Vimy Ridge.
