In a recent blog comment, Neil Burton asked if I could provide some sources for warfare in 17th Century Eastern Europe. I’m afraid most of my detailed sources are in Polish but there are some useful Ospreys and a growing collection of material in English on the Intranet.
Polish Armies 1569-1696, by Richard Brzezinski, is published in two volumes by Osprey (numbers 184 and 188 in the Men-at-Arms series). Volume one concerns the ‘national’ Polish formations and volume two is about the ‘foreign’ section. The illustrations by Angus McBride are particularly good. These books only suffer from the limitations of the format: while a great introduction, they barely scratch the surface of the wars of this period. Richard Brzezinski wrote another useful book for Osprey in the Warrior series, published in 2006, called Polish Winged Hussar 1576-1775.
Another really helpful source of information are the rules With Fire and Sword, by the Polish company The Wargamer. They provide lots of information about the different troop types as well as campaign backgrounds and tailored orders of battle. I am not attracted to the rules themselves but they are still worth getting for the background material and illustrations.
On the Internet, there is a lot of English language material on Wikipedia. The following links are good starting points and each will take you to several other useful pages, especially about battles.
The following site is dedicated to Polish renaissance warfare.
The last site to recommend is the home page of a re-enactment society, which contains a varied mix of useful articles, from dress and equipment to discussions about tactics. I have spent a lot of time on this site and really enjoy searching it.
In case you speak Polish, these are books I have picked up for myself in recent years. New titles appear regularly and it is worth entering the name of a battle on Amazon to see what comes up. I found the two books about Cudnów (1660) that way.
i wish this period and theatre was easier to access, since I find it so fascinating. But by looking here and there across the Internet, you will find a great deal of interest.
