Yes,
Southern Storm is wonderful because it is literally a day-by-day account of the march, taken mostly from the diaries of the soldiers who actually participated. We discover that an awful lot of what we
think we know about that event is false or exaggerated propaganda that has been mindlessly perpetuated lo these many decades.
Southern Storm is a much-needed and very welcome sort of antidote for the
Gone With the Wind mythology.
If it makes any difference to you,
@randoke, both
Southern Storm and
Sherman's Civil War, while being very good reads, and important books if you really want to understand Sherman, are both quite long -- 548 and 909 pages, respectively, exclusive of appendices, indexes and endnotes. If you would like a good, relatively quick read as an introduction to the man,
Fierce Patriot, on the other hand, is 352 pages, exclusive of end materials. And it will give you an overview of Sherman's
whole life, not just the Civil War part.
On the other hand, some people find the 3-part construction of
Fierce Patriot distracting. If you want a more straight-line chronological biography (if less cracklingly written), I have heard good things about those by
John Marszalek and
B.H. Liddell Hart.
