I've just got the audiobook version of "HMS Ulysses". I've read the paper version a few times already - roughly once every five years. Far-fetched in some aspects but a real page-turner. I think it inspired some scenes in "HMS Nightshade" a comic strip in "Battle Weekly" which also had some great series' like "Charley's War" and "Johnny Red".
I'm also listening to "Pickett's Charge" by Philip Thomas Tucker. I'm not too sure about this one. The author says he sets out to bust some of the myths of the "Lost Cause" argument, but blames Longstreet for much of what went wrong, which if I remember correctly was a central pillar of that same Lost Cause Myth. His other main argument seems to be that Lee's plan, far from being ill-thought-out, was actually a stroke of genius because it envisaged a simultaneous attack from the rear by Stuart's cavalry, which never happened. Maybe it was a brilliant plan in the way Market Garden was a brilliant plan in that everything had to go right for it to succeed, which in the real world would mean it wasn't a great plan at all. He also claims that other similar attacks were made in the 19th century on defended positions on higher ground but doesn't give many examples apart from Chapultapec about which I can't comment. He references Austerlitz and Marengo (he references Napoleon a lot) but these seem to me to be very different kinds of battles. Napoleon was under attack and losing badly at Marengo and at Austerlitz the Russo-Austrians thought they were the only ones doing the attacking, so the fight for the Pratzen heights was more of an encounter battle.
Tucker also tries to take the emphasis off the Virginian contribution i.e, Pickett's division, claiming that other divisions actually performed better, particularly the North Carolinians (I think). We'll see how things progress. A criticism of the style would be that the author seems to think that if a point's worth making once, it's worth making ten or more times e.g. the fact that Lee's plan would have given him an 8-1 numerical advantage at the critical point(???) - more investigation needed by this reader, I think, and did you know that the copse of trees wasn't that tall, but was easy to see from all round because of the higher ground on which it stood? I know that now, and if I have to hear it one more time....
