Back in the First World War, there were times when soldiers needed to move things like food, ammunition, and other supplies across difficult terrain like mountains or rivers. To help with this, they would use something called a military cableway.
Think of it like a really long clothesline up in the sky, with baskets that could carry stuff back and forth on a cable. These cableways could span across great distances and heights, like over a canyon or a valley.
The baskets were controlled by soldiers who would pull ropes to send them back and forth. It was a lot like playing tug-of-war on a really big scale. The soldiers had to work together to make sure everything was moved safely and efficiently.
Military cableways were really important in the war because they allowed soldiers to quickly transport supplies to where they were needed without having to climb up and down steep hills or swim across dangerous rivers. Plus, they were pretty fun to use!
