This book is just over 100 pages. It gives a pretty good account of Tannenberg, yet has few maps. The Brusilov offensive is very breif, 13 or 14 pages as is true in most books unfortunately. Most of the information in the book is accurate, barring just about all of page 97, which is uninformed at best. This page discusses the western front so it can be excused. The correct version of page 97 should read , the American expeditionary force destroyed the Germans at St. Mehiel and so Ludendorf asked for an armistice, the Balkans were a side show. Read "The Myth of the Great War," John Mosier, for a better explanation. The book is a good primer for the eastern front, and sadly in the english language there's not much after that. Any good book on WWI Suggests Norman Stones book The eastern front 1914-1917 as it's main source, however unfortunately, it's the only source. One final comment, Mr. Clark writes that Evert's offensive was originally scheduled for June 9, 1916, I believe it was scheduled for June 14 originally.
