First, the prisoners held by the Germans wanted to be free, so they began to plot to dig tunnels to escape.
Film background: During the Great Escape of World War II, the Germans were actually more humane soldiers. They treat prisoners of war very well, not only providing delicious food, but also providing good accommodation. To put it bluntly, as long as you stay in prison honestly, not only can you live well, but not everyone wants to enjoy this life, so the prisoners of war began to find ways to escape from here. Surrounded by officers and men, they decided to dig a tunnel to escape.
Second, as long as the digging tools can be used, we should take out the excavated soil and throw it away with a cloth bag.
Now that it has been decided, let's begin. The prisoners secretly left everything they could dig up, such as spoons, plates, jars, etc. And remove the bedplates supporting them to prevent them from collapsing when digging tunnels. As the tunnel gets longer and longer, the problem of soil becomes a bit tricky. At this time, it is suggested to make underwear and towels into cloth bags, and take out the excavated soil bit by bit, so that 100 tons of soil is quietly moved away.
Third, the calculation error caused the escape failure by digging three meters less.
In this way, they dug secretly for several months. As long as the tunnel is dug successfully, they can go back to their country and their families. Unexpectedly, they didn't calculate the length of the tunnel, so when they dug it out, they found that the tunnel was three meters shorter than expected. In this way, the people who just went out were discovered by officers and men, which led to the apocalypse. In the end, only three people managed to escape, and the rest were either executed or imprisoned.
