Below are selections from Operations on the Vistula in August 1920, from the Polish standpoint.
A collection of articles translated from the Polish into Russian by the Soviet Military Publications Division 1931. Then translated into English at the Army War College, Washington D.C. in 1934. Previously put on-line by the US Army Military History Institute but since moved.
Unfortunately the version given is a very poor carbon copy with the place names in the German forms. I have typed it up, sorted out the place names, and split it into separate sections.
A detailed look at the fighting on the Warsaw Bridgehead in mid-August, especially that around Radzymin and Minsk-Mazowiecki. A nice series of engagements for historical scenarios, because the sides were so evenly balanced. And, of course, the Poles used armour.
A detailed look at the initial stages of the counter-attack south of Warsaw from 16 to 18 August.
A rather tedious discussion of the theoretical basis for the the Polish campaign in August 1920. I have only kept this one for completeness.
An article about the decision made by Pilsudski to fall back to the Vistula and counter-attack from behind the Wieprz. Although covered in general terms in other available books, this article gives much more military detail about the failure of the Poles to hold their previous defensive lines in late July and early August 1920.
The original article came with four maps, only three of which are attached in the on-line version. These basically relate to Parts 1 and 2 above.
If trying to follow the text in greater detail, or if interested in gaming the battles, the site below is extremely useful. It has topographic maps from the 1920s and 1930s for all of Poland. Radzymin is in P39 S32.
Many of the places in the text are extremely difficult to locate, some being very small indeed. I have prepared a document that locates them (with a couple of exceptions that no amount of searching could find).
