My grandfather served in the war as a commander of the artillery battery. He told me this story:

Once, after a hard night, he slept to rest next to the weapon, and slept unnoticed for himself. And when after some time I woke up, I saw the guns rolling from the shells next to the weapon.

When asked where this dirt came from, the soldiers replied that the order had come by several raids to drive away the German tanks that appeared to be in the distance, and for such a nonsense they did not wake the commander.
