"This series of six volumes recounts the adventures of two brothers, Tom and Jack Somers, one in the army, the other in the navy, in the great Civil War. The romantic narratives of the fortunes and exploits of the brothers are thrilling in the extreme. Historical accuracy in the recital of the great events of that period is strictly followed, and the result is, not only a library of entertaining volumes, but also the best history of the Civil War for young people ever written." +Boat Builders Series.+ By OLIVER OPTIC.
