many congratulations on your book, I look forward to getting a copy in the summer. Incidentally you may have noticed that within the Civil War background of the novel, while it is the northern columbiad technology of the Baltimore Gun Club that sends three astronauts in to space in
From to the Earth to the Moon it is the southern technology in
Around the Moon that
brings the astronaut back to earth safely again in the splashdown. The 50:50 Unionist / Confederate split is important to Verne (who was fiercely pro northern) as it shows what a reunified America can achieve.
The main links re the Confederates in the splashdown (Chapter XX The Susquehanna takes Soundings) are the named references to John Mercer Brooke, (the designer of the ironclad monitor CSS Virginia as being pitched at a 38 degree angle to make it immune from northern columbiad cannon) the inferred reference to Matthew Fontaine Maury (first identified the telegraphic plateau 'a level seabed' for Atlantic cables, and his first ship being the USS Brandywine / Susquehanna) and Admiral Raphael Semmes of the CSS Alabama (like Maury served on the USS Brandywine / Susquehanna hence the reference in the novel to both 'Susquehanna' and 'Brandygrog', and who has all the behavioural traits of Captain Blomsberry in the novel.
Maury's business partner (before the Civil War) Cyrus Field is also mentioned in the same chapter, although Field as a northerner advised Abraham Lincoln on the importance of telegraphy in winning the Civil War.
I hope to complete a short paper on the 50:50 Civil War political background of the splashdown in Verne's Around the Moon in the near future.
Best John
