The author's potential contribution to the study of HMS Hood lay in recording the memories of her crewmen. Surprisingly though, the "recollections" section takes up a mere 40 pages--published separately as a booklet, this might have been worth a modest price. Here I will discuss the remaining 100+ pages with their focus on technical/historical material: warship design, naval combat, and battle history, none of which Norman understands. From a vast list of errors, I have selected a few representative examples.
NORMAN on warship design: Regarding deck protection, "Hood's armor was not plate, but of the cemented type...." This is pure gibberish. Hood did have British C armor ("C" for "cemented") in thicknesses up to 15-inch, but not on her decks, which instead had lesser steel with no individual plate more than about 2-inch. No mere detail, this bears directly on the cause of Hood's loss, and the author cannot even correctly parrot the fundamentals.
NORMAN on battle history: "Most, if not all [of Bismarck's shells], failed to explode or did so only partially." In reality, German shells indeed underachieved, but it was Prinz Eugen's ammunition that gave a demonstrably poor performance, not Bismarck's. Norman says that, if Bismarck hit Hood with a shell, "chances were that it had not exploded"--opening the door for his theory that Eugen fired the fatal shell. Norman's theory depends on ignorance of the basic facts.
NORMAN on naval combat: When sunk, Hood was "well within" her immune zone, "defined as a range no closer than 12,000 yards, and the outer limit beyond 25,000 to 30,000 yards." The concept of an immune zone--the area where both the belt armor and the deck armor are likely to resist the armor-piercing shells--did not apply in this instance for the simple reason that Hood had no immune zone. Quite the contrary, through much of Norman's specified zone, neither Hood's belt nor her deck would suffice to keep out Bismarck's shells. She was doubly vulnerable! But Norman again is steering us toward his Eugen theory, puzzling though it is--if Hood was immune to Bismarck's 800kg armor-piercing shells, what could Eugen achieve with shells that were 122kg and not armor-piercing? Norman claims Eugen's shells could by-pass Hood's armor, plummeting straight down Hood's funnel, though he offers no explanation how the shells could achieve the great heights necessary for this trajectory. In fact, Eugen's shells were descending from an angle only about 20 degrees above the horizontal; so unless the Germans managed a bank shot off a low-flying billiards table, this theorized hit was physically impossible.
Given the availability of many fine books on Hood and Denmark Strait, this one earns little regard. The final word on Norman's research appears on page 82 with a photo captioned "Hood at speed"--a dramatic photo which, unfortunately, depicts the battleship Royal Oak, a ship four years older than Hood and from an entirely different class.
