I have read an article about a German general a year ago, which I found very interesting, but I forgot his name, and since then I changed my computer, so I don't have the browsing history either. If you could help me to find out who he was, I would be most obliged.

The things I remember (maybe correctly, maybe not):

• His family came from Hannover, and his great-grandfather (or grandfather?) was an officer (maybe even general?) in KGL under Wellington in the Peninsular War.

• He had an armoured division on the Eastern Front in the time of Stalingrad, and he obliterated a whole Soviet corps piece by piece in the course of a few weeks. Generally the Soviets broke through the overstretched German defenses somewhere every day, then the general encircled them with his division overnight, and routed the attackers with a surprise attack in the dawn.

• His motto was not to give out written orders, he always spoke with his underlings face to face, to minimise the chances of misunderstandings.

I think that's it, I am sorry that I remember so little, and thanks for the help in advance.
