It was on one of the history type channels. I too had never heard of it but they did say it. It doesn’t sound like one they would make up tho.
I have lost a lot of confidence in those shows recently. They had one on Midway a few days ago with glaring errors. They said that we had 4 carriers at Midway and also said we sank all 4 Japanese Carriers on the same day.
I saw that and said “What the what?”
Perhaps the documentary channels current reliance on inferior programming and infomercials has caused good filmmakers to seek other pastures. Not unlike when MTV injured music when it went (c)rap. Just another part of the dumbing down of America.
