Prit Buttar has been responsible for some truly epic pieces of work for us so far. Battleground Prussia and Between Giants were fantastic books, not least because they tackled a somewhat overlooked facet of World War II - the Eastern Front and the Baltic states. 

Now Prit has returned with another epic - this time exploring the Eastern Front in World War I. Collision of Empires lifts the lid on the fighting between Imperial Germany, Austria-Hungary and Russia at such monumental battles as the Masurian Lakes and Tannenberg. If you thought that catastrophic losses for little territorial gain were exclusive to the Western Front at battles like the Somme, this book will prove otherwise.

It's a volume that in many ways completes the picture of World War I, so if you are interested check out this free PDF download
