Wikipedia claims the following. Ignaty Karpezo was a general during WWII. After a heavy bombing he was found without signs of life. A medic determined death. He was buried consequently.
But after a while the unit was visited by the superior ranks. They heard that a general was killed. They said that Soviet generals do not die and ordered to open the grave. Surprisingly Kaprezo was found alive and lived till 1987.
I wonder how and whether it is true.
