Here we go again, I hope it won't cascade into Brisbane.
Of course it was 1815, my bad. Between 20 and 50 percent (estimates vary) of all German (not only Prussian) students volunteered in this war, so it quite heavily shaped academia afterwards.1. I think you will find Napoleon was finally defeated by a coalition of Prussians, Dutch and British forces outside of a village in Belgium called waterloo in 1815. There were I think some other odd and sods there too.
