Collision of Empires is highly detailed, as one might suspect considering its sharp focus on the first few months of the war. The author begins with respective chapters on Germany, Austria-Hungary, and Russia's political and military cultures before covering the opening campaigns. Illustrations are generous, but the maps leave one wanting; there are precious few of them, they only show attack routes, and they're so zoomed in that an atlas is in order to get a reader's bearings. There's no faulting the overall narrative, though, which combines a seasoned east-European historian's commentaries with a fast retelling of the war. According to an interview with Buttar, this is the first part of a trilogy. I look forward to the rest.
