I don&#x27;t know much about Mongols in Central Europe, so probably true: they were far away from the steppes, probably lacked siege machines, etc.<p>Also, in the lands of Rus&#x27; stone fortifications were a very rare thing - there&#x27;s almost no suitable stone for contstruction, so most castles and fortresses were wooden, so they did burn.<p>None of the stone fortresses in the north, where there are suitable materials, were plundered, AFAIK, so you must be right.
