While in the 1860s (see below) you might - if you are interested in reenactment of this period - find this film of a reenactment of a battle fought between the Austrians and Prussians in 1866. Very interesting film - I am impressed by the numbers - who are these groups? Photos here - 1866 portal - with more footage
Mladějov - Blosdorf 1915 Some of them are Czech and the guy who posted this footage also put some very good quality clips, three in total, of a World War One reenactment near Blosdorf village that involves all manner of interesting bits of equipment - trains and vehicles .... recommended for history fans. Photos here - organiser's site with more photos.
