Rating and reviewing this book is sort of difficult. It was an incredibly interesting and very detailed first hand account of the most famous maritime disaster in history, but at times it seemed a bit... too detailed.
The first part of Colonel Archibald Gracie's portion of this book read almost like a novel. He told his experience, splashing in details he learned later. Then he rewound and accounted for the experience of every single lifeboat, often times from many different accounts. I don't doubt that this information is invaluable to history and I commend Gracie for taking the initiative, in the few short months he had to live after the disaster, to collect all these stories from so many different perspectives. But, to read it flat out is a bit dry. Gracie was a military man. He wrote books about is experiences besides this one, so he was clearly no stranger to words, but his style is informative. I took this slow, reading it over about a month. This is the only real way I can imagine reading this torrent of information. But if you're interested in the Titanic this really is an invaluable resource.
The second portion of this edition, I dare not say half as it takes up only about forty pages, is written by John B. Thayer who was seventeen at the time of the sinking. Both he and Gracie survived by clinging to the overturned collapsible lifeboat B. Thayer's account is really far more compelling to me, it's told relatively linearly and only includes his experience of things. He also does not shy from his opinion that the ship broke in two (a fact we now know to be correct) before plunging below the waters despite the insistence from the crew and decision of the inquiries that it did not.
Gracie died of illness relating to his night of exposure awaiting rescue from the Carpathia on December 4th, 1912 so his account was written very soon after his rescue. Thayer's account was not published until about 1940. Take from that what you will. Both these tales are extraordinary. I'd recommend them to anyone, but perhaps only in small doses.
