China Rising Book

Unusual book, I think it tries to make an interesting story into a sensation so that leads to a disappointment. The second voyage was the most interesting and contained the fewest details. I am also disappointed by some of the errors in simple descriptions such as the various naming of the vessel bridge. The book claims that a myriad of navigational such as light vessels, buoys and shore stations transmitted underwater signals, that could be received by a hydrophone receiver in the ships hull, not a technology that I was aware of for normal merchant vessels even now. The book also claims that a position from a Direction Finder may be assisted by getting a range from signal strength! The book cover also states that the Bremen undertook her passage foregoing Radar, must have been a rare vessel in 1939 equipped with radar? Simple errors like this make on query how much of the rest is also wrong. I did find the details of the Soviet assistance in Murmansk interesting.
