TIL I learned that Innsbruck is named for the River Inn. I actually came to it the other way: The Inn Valley is mentioned in the book I'm reading about a WWII battle in Austria that took place near Worgle, from which I figured there was probably a river at the bottom of the valley, and I wondered if it ran by Innsbruck. Sure enough. According to Wikipedia "Innsbruck" means "bridge over the Inn." The name Inn doesn't appear to relate to the English word inn. Wikipedia says the river's name is derived from a Celtic word, en or enios, which meant water. They note that the river was once called the Wasser, which means water in German. A river named 'water' seems a little on-the-nose, if you ask me, but alright. Also, searching Google for the River Inn turns up a whole bunch of inns on rivers. I searched for "Inn Valley" instead and then the first result is the river.
TIL that in April 1945, Heinrich Himmler ordered that all males aged 14+ residing in a home displaying a white flag should be summarily executed. Civilians were trying to announce themselves to the advancing Allied armies. In some cases, such as in Austria, civilians would show a non-[National Socialist] flag, such as the pre-1938 Austrian flag. Of course many soldiers and police were ignoring the order, but some diehards - SS and Gestapo, for some - were actually carrying it out, enough that some Wehrmacht looking forward to the end of the war had to worry about the civilians around them, and not (just) because of the advancing Allied armies. In the book I'm reading, a Wehrmacht Major - German, not even Austrian - was so worried that the SS he was embedded with would start executing civilians that he became the military commander of the local resistance cell and helped them stockpile weapons and ammunition to defend themselves against the crazies, German-on-German, until the Americans could arrive. I knew a little bit about this particular battle at Schloss Itter before I started reading the book, and I knew that part of the story was that the risk to civilians from the SS prompted a Wehrmacht unit to side with the Americans, but I didn't realize it was a broad order from Himmler and not just a few "last stand" nutjobs going fully 'round the bend. So I'm wondering now whether this sort of thing happened in other places across Germany.
