[.ca] Copse 125: A Chronicle from the Trench Warfare of 1918 (ISBN 0865274452)

only for the serious:
a reprint with poorly reproduced text. Its a good memoir from a German officer, with some ripping good bits. However, at least half or so is a lot of self reflection. So if you are really into the German side of WW1 in a scholarly way iots a great source. If you just want cool tales of fighting pass it up.

Philosophy vs. Memoir:
Storm of Steel, Junger's more famous WWI memoir, is an excellent book, capturing a young patriotic German's response to trench warfare. It's full of details of daily life in the trenches and has a particularly good passage of his involvement in the Kaiserschlacht offensive. By comparison, Copse 125, only contains a few pages of war memoir. The balance of the book is philosophical tract based on zealous nationalism. If you want to read several hundred pages of why Imperial Germany deserved to win the First World War and rule Europe, well, be my guest.
