To be sure, the burning of the library happened during the early days of WW1, which had neither nazis, gestapo, nor Nuremberg trials.

It was burned down twice, in 1914 and 1940

I think the source of confusion is the use of “at the time” in your previous comment, which is talking about events in WW2, when the article discusses events in 1914 with no reference to 1940.

The cause in 1940 was apparently an artillery duel between German and British troops, which is on a different level from purposefully setting fire to a library within an occupied city, even if the result is equally terrible.
