I’m currently reading Theodore Roscoe’s United States Submarine Operations In World War 2. This particular edition was probably a first edition published in 1949(!) by the United States Naval Institute Press. It’s even looks like it was published in 1949:
From the preface:
This volume is not the official operational history. Strictly speaking, it is not a history, nor is it to be studied as such. Herein, in the narrative form, the reader will the inspiring saga of submarining. For the student, the technical side is featured. And many aspects of submarine warfare which would ordinarily be excluded from a purely historical text are detailed and discussed.
It’s in my care for now, on loan from the Pritzker Military Library. I wanted to see if there are historical parallels between the sub campaign in the pacific to seeing how reasonable it would be to use SSNs/SSKs to contain the PLAN within the first island chain.
Going through the first chapter I found this enclosed in the book:
It’s an unknown newspaper clipping detailing the moorings of Pearl Harbor on the morning of December 7, 1941 at 7:55am.
The other side of the clipping features an ad for a book called “Home Before Dark” by Eileen Bassing. According to a quick Google search it was first published in 1957.
That leads me to believe the map and newspaper were published in 1957.
The map itself is very interesting as it details most of the ships in port and even tells I what some witnesses were doing moments before the attack.
Even more unusual, the paper left a stain on the page which makes me believe maybe it hasn’t been seen since 1957. Who knows.
Anyway, this is a treasure map and maybe, if the reader know more than I, of some historical significance.
Just amazing…you never know what you’re going to in and on these books.
The Lexicans 
Your library uses little stickies on the book for the due date? How quaint!
Yeah. I hate that.
A treasure map, indeed. What a great find for you… and now us.
Excellent book…
“I wanted to see if there are historical parallels between the sub campaign in the pacific to seeing how reasonable it would be to use SSNs/SSKs to contain the PLAN within the first island chain”
The only parallels I could think of would be for the skippers of modern boats to not become mired in how things “should” happen according to doctrine. We tried that at the beginning of the Second World War and the Old Guard was gradually replaced by the younger, more aggressive, and creative skippers due to the slow start and dogged adherence to tactics which didn’t work – submerged attacks on sound bearings, reluctance to use the deck guns, ect.
Give them the overall gist of what is the tactical and strategic goal and let them run with it…
