Comments by "Winston Smith" (@kryts27) on "The Heroic End of HMS Rawalpindi and HMS Jervis Bay" video.

Scharnhorst and Gneisenau were battlecruisers, not battleships, i.e they were a little undergunned in calibre with 11" main guns, most battleships had 14" guns or bigger in that era, her main belt armour was 50mm thick, thin for battleships at that time, although her 105mm sloped longitudinal armour might have classified her as a battleship. For example modern mid-1930s RN battleships, e.g King George V class had 137mm main armour over machinery spaces. However, Scharnhorst alone was a deadly opponent one-on-one for any warship less than battlecruiser class. The HMS Ramupindi, a converted ocean liner auxillary cruiser, did not stand a chance.

The tragically heroic loss of HMS Jervis Bay to save an important convoy was legendary, but it is also a incidement of the RN Admiralty in the importance of defending Britain's most important lifeline to stay in the war. The Admiralty, despite the losses of U-boats from World War 1 was underprepared by a paucity of destroyers and corvettes to deal with the U-boat threat threat early in the Battle of the Atlantic. However, the Admiral Sheer was built precisely for that purpose deployed when she ambushed the large trans-Atlantic convoy, HX 84. The liner was Australian, as was her captain, but her valiant merchant marine crews came from all over the Commonwealth, notably Bermuda, Scotland and Canada. The lack of cruiser warships by the RN and her allies needing to fight a war in two theaters (North Atlantic and Mediterranean at that time) to escort large convoys was a factor in her demise. The RAN would do well to name a permanent naval vessel after her. Particularly a supply or transport ship.
