First was an ebook, Osprey Campaign #29: Omdurman 1898: Kitchener's Victory in the Sudan. During that era, more photography was already taking place, and so there's a lot of visual material in this book, as well as plates and maps. Fairly interesting.
Second was Helmet for My Pillow: From Parris Island to the Pacific which is a recollection of the US Marine experience of the author. The book was a significant portion of the material used in the HBO series Pacific, about the Marines in WWII. Although there's some good material in here, I wasn't as moved by this book as I'd hoped to be, nor did I find it all that useful in understanding the campaigns. It deals almost exclusively with the soldier-eye-view of each battle Leckie was sent to. Not bad, but not a keeper.
