This is the cover of Sketches from the North American War, 1861-1865: Letters and Notes During a Four-Year Stay in the United States of America in this War by a Participating Swedish Officer by Johan Anton Adolf Carlsson Warberg
Lieutenant Colonel Johan Anton Adolf Carlsson Warberg published his two-part memoir in Stockholm in 1867. The Swedish title Skizzer från nord-amerikanska kriget, 1861-1865: Bref och anteckningar under en fyraårig vistelse i Förenta Staterna / af en i detta krig deltagande svensk officer translates to English as Sketches from the North American War, 1861-1865: Letters and Notes During a Four-Year Stay in the United States of America in this War by a Participating Swedish Officer.
Digital copies of Warberg’s memoir are online at HathiTrust and Internet Archive courtesy of hosting institutions such as the Library of Congress, New York Public Library, and the University of Minnesota. Some — not all — include the highly illustrated cover displayed in this post. Warberg’s memoir includes maps and illustrations of people and events. I’ve not come across a translated volume of his memoir but several free Swedish-to-English translator options are available online.
