This is an ETO story, but when my future college roommate and I were in High School, we had a weird history teacher. She knew her art history backwards and forwards, but she had some unique opinions about military history. She asserted that the Japanese assisted the Germans in trying to prevent the evacuation of Dunkirk. When we called her on it, she claimed the IJN sailed around the north end of Russia to get there. My future roommate made such a stink that she let him go to the library and bring back numerous sources to refute her.
Fortunately, this was not the normal level of education I got. We still laugh about it when we see each other.
PS - She later asserted that the Battle of Trafalgar wasn't very decisive. You can't make this stuff up.
I had a science teacher like that in 8th grade. My sister was in grad school studying Geology at the time, so I had picked up a lot more science than a typical 8th grader from her. There were a few instances where I locked horns with the teacher, but most of the time I rolled my eyes and kept my head down.
I wonder if she had heard somewhere that Italy had declared war on France and the UK during the Battle of France and confused that with Japan? That's the only thing anywhere remotely close to what she was saying. And I don't believe Italy had anything at all to do with Dunkirk, though there were some Regia Aeronautica units that went to northern France during the Battle of Britain. Their contribution was fairly minor though.
If you really want to get your blood pressure up, you should check out this guy: http://douglasdietrich.com/. I've heard him on the radio a few times and I end up yelling at the radio. He claims to be such an expert, but many of his claims are physically impossible. He'd be more believable if he claimed Japan used enslaved fairey folk.
