Historical Context

The Great War had turned into a long and sad standoff by 1917. Millions of soldiers sat in deep dirt ditches called trenches. Neither side could move forward for very long. The Germans held a high ridge near the town of Messines in Belgium. This high ground gave them a great view of the British troops below. The British generals wanted to take this ridge to stop the German attacks. They spent many months planning a secret way to win. They knew they needed a special trick to break the heavy German defenses.

What Happened?

The British army brought in skilled miners from coal mines across England. These men dug long tunnels deep under the wet ground. They worked for over a year to reach the German lines. They walked silently in the dark tunnels to stay hidden from the enemy. Once they were deep under the ridge, they moved in huge amounts of explosives. They placed these bombs in nineteen secret chambers under the ground. On the morning of June 7, 1917, the soldiers finally got the order. They pushed the buttons to set off the giant bombs all at once. The entire ground shook like a massive earthquake across the region. People miles away heard the loud blast as the earth blew upward. Huge fires lit the sky and the German ridge collapsed into ruins. Thousands of British soldiers then marched quickly across the broken field. They moved so fast that the German army could not stop them. The British captured the ridge in just a few short hours that morning. This was one of the most successful attacks of the entire war.

Why Did It Matter?

It was a major tactical win that proved tunnels could be used to break enemy lines. It also boosted the morale of the Allied troops.

Frequently Asked Questions

1How loud was the explosion caused by the mines at the Battle of Messines?
The blast was one of the loudest man-made sounds in history. People in London reported hearing the massive roar travel across the sea to England.
2Why did the soldiers spend so much time digging tunnels under the enemy?
Digging tunnels allowed soldiers to move deep under the enemy lines without being seen. This let them plant bombs to destroy tough defense positions.
3Who was chosen to perform the dangerous work of digging these deep mines?
The army recruited skilled coal miners from civilian life. These men were experts at digging through hard earth and knew how to stay safe underground.
4Did the German soldiers realize the British were digging under them?
The Germans were suspicious and tried to listen for digging noises. However, they failed to find many of the secret tunnels before they were finished.
5How deep were the tunnels that the soldiers dug into the ground?
The tunnels were very deep to stay hidden. Some were over 100 feet below the surface. This protected the miners from bombs going off above the ground.
6Exactly how many mines were planted beneath the ridge to be exploded?
There were 19 huge mines planted under the ridge. They were all set to blow up at the same time to break through the German defenses in one go.
7Did every single mine explode exactly when the soldiers planned?
Most of the mines went off right on time, but a few failed to detonate. These unexploded bombs stayed hidden under the ground for many years.
8What exactly was the Western Front during the First World War?
The Western Front was a long line of fighting that stretched across France and Belgium. It was where the British and German armies faced each other.
9Was it dangerous for the soldiers to dig these tunnels for the army?
Digging was very risky because the dirt could collapse on them. Sometimes the enemy would dig their own tunnels to intercept and attack the miners.
10Did the secret mines help the British army win the battle quickly?
Yes, the mines destroyed the enemy's defenses instantly. This allowed the British soldiers to capture the important ridge in a very short time.
