Cross-Channel Attack, by Gordon A Harrison, is one of many that US Army historians published to document World War II. Although the main combat covered is from D-Day to the capture of Cherbourg the first half of the book (about 250 pages) the history of planning for Operation Overlord, the politics of making it all happen (the British were mostly against an invasion through France), and the logistics of assembling men, supplies and ships.

Once we get to the invasion the combat details are fairly good though it does have to jump around a lot as there were many units involved — luckily British activities are outside the scope of this book other than broad overviews of how the affected American activities. Combats have a lot of small anecdotes and a lot of names and places. There are also many backs at the back of the book so you can follow the general action.

Overall still mostly relevant seven decades later. Lots more stuff has come out since then (for example Allied decryption efforts are maybe mentioned once or twice but much of that stuff was still secret when this book was written) but I think for the most part it’s a mostly accurate telling. It’s readable enough that it makes me interested in reading the other volumes (well, not all of them but at least some).
