As I have around a total of 1 hour of travel time to and from work I realized a great time to spend it was to do some reading of the many books I bought a while back.
I started out reading the book titled (when translated into English) "The combat operations of the Volhynian cavalry brigade: First phase of the September campaign 1939" by Marcin Paluch.
This is an interesting book written very much like an essay, the author explains the background of the equipment, organization and preparation for war that the cavalry brigade went through, as well as allowing the reader to follow the combat operations of the opening days of the September campaign when the Volhynian cavalry brigade was made famous for their fighting at the battle of Mokra with the support of armoured train nr.53 "Smialy"/("Bold").
I figured it would be nice to share some historical information as I make my way through the book - since it is in Polish and I'm not sure if there is a English version out there.
Part 1 is discussing the equipment of the Polish cavalry brigades, part 2 will be about Polish cavalry tactics and part 3 will be about the Volhynian cavalry brigade and their battle against the German 1st and 4th Panzerdivision at Mokra.
