KG 54's attack on Rotterdam in May 1940 has occasioned accusations of war crimes but no criminal charges were ever filed against the wing's officers or any senior officer commander at corps or air fleet level. The bombing was discussed at the Nuremberg trials in relation to the conduct of senior Luftwaffe commanders, particularly Hermann Göring, commander in chief of the Luftwaffe and Albert Kesselring, commander of Luftflotte 2, to which KG 54 was attached.[3] The decision to bomb the city remains controversial.
