Grant here gives a consistently interesting account of his role in many of the major campaigns of the Civil War. His prose is clear and his accounts of battles and strategies quite readable, even to those without particular expertise in military history. He sticks to the story, making few attempts to even scores with his numerous critics in the Army or the press.
One thing that should be noted is that these 'personal memoirs' are in many ways remarkably impersonal. There is only a quite brief account of Grant's youth, and his wife, to whom he was apparently quite devoted, is barely mentioned. Grant tells the story of his career as an officer with increasing levels of responsibility, but says little about himself. Also, the memoirs end with the assassination of Lincoln, and do not at all discuss his presidency.
The edition I read was lacking in maps, which was a serious drawback, however it was a different edition than the one discussed here. Because so much of the book focuses on the tactics of specific campaigns, a good set of maps is a very valuable addition, and would be advisable to check for in any edition you consider reading or buying.
