In a world where information reigns supreme, the legacy of the Signal Corps, as documented in this brief report about its activities in 1865, speaks directly to our innate human desire for connection, clarity, and understanding.The ability to transmit and receive information quickly, accurately, and securely remains paramount, with today's cryptographic security agencies facing challenges similar in principle to those faced by Signal Corps during the tumultuous years of the Civil War. This report reminds us that the quest for seamless connectivity remains a timeless pursuit, as relevant today as it was in the midst of a nation divided.

The book is part of In the Year ... series, in this case 1865, for which Nimble Books reprints books that help the curious reader make a "transect" through the year in question.

Most other volumes in the series are much longer.
