From Landau's diary:
"At 6 a.m., I am suddenly wakened from a deep sleep. Fall in line for an execution. Alright, I'll play the role of the executioner and after that the gravedigger. Why not? It is strange. A man who loves to fight has to shoot up defenseless people. 23 are supposed to be shot. Among them are the two women I already mentioned. They even refuse to drink a glass of water. I'm told to be one of the sharpshooters. I'm supposed to shoot any prisoners who attempt to escape. We drive along the road for a few kilometers. We then go to the right, into the forest. We are only 6 men at the moment, and we are looking for a suitable place to shoot and bury them. After a few minutes, we found a spot. The condemned line up with shovels to dig their own graves. Two of them are crying. The others are amazingly courageous... The condemned are divided into three shifts, since we don't have enough shovels here. It's strange, but I don't feel anything inside me. No sympathy - nothing - that's how it is - so everything's okay for me... The hole slowly gets bigger. Two have collapsed from crying. I always let them dig longer, so they don't think too much. While they're working they are actually calmer. All their valuables, like watches and money, are place in a pile. The two women are taken to the one end of the ditch after everyone has been taken to a clearing nearby. Six men have been chosen to do the shooting.
3 men are to aim at the heart and 3 at the skull. I take the heart. The shots ring out, and brain matter is sprayed everywhere. That's too much: two shots at the skull. The skull is literally ripped away. Almost all of them drop to the ground without a sound. But with two of them it doesn't work. They cry and whine for a long time. The next to the last group has to throw those who have already been shot into the mass grave. Then they have to line up themselves, and they fall in all alone. The last two have to stand right on the edge, so they fall in correctly. Some of the dead bodies are resituated with the rake, and then we begin to do our work as gravediggers. I'm dead tired by the time I get back, and we have to start our work. We have to clean up everything in the building."
