View Full Version : Need info about Scapa Flow attack

02-18-2008, 03:43 AM
On 13 october 1939, GŁnther Prien, captain of U-47 penetrated the defenses of Scapa Flow and managed to sink HMS Royal Oak.

However some sources claim that he also managed to destroy or damage HMS Pegasus, a seaplane carrier. Does any of you have some info about this?
(and don't quote Wiki, plz)

Nice find, but I need the info about the HMS Pegasus (ex-Ark Royal, from 1934) Was it really serving through the war, or was it destroyed in 1939, and the documents about her convoy escort role were faked?

You might be able to get more info over at the Silent Hunter Forums.

What makes you think that the Pegasus was sunk and the records faked? And what on earth would be the point of faking the records?

Mercantile hull purchased in 1914 by the Admiralty during construction for conversion into a Seaplane Carrier and to be named ARK ROYAL on launch. This ship had been laid down by Blyth Dry Dock on 7th November 1913 for use as a collier. She was the modified with bridge and machinery fitted aft to suit her new role. A flying off deck was fitted in front of the bridge with cranes installed for transfer of aircraft to and from the sea. This ship was launched on 5th September 1914 and completed on 10th December that year. After WW1 she carried aircraft to the Middle east and also acted as a minesweeper depot ship before being deployed for research and development of catapults and recovery of aircraft by warships. She was renamed PEGASUS in 1934 when her original name was selected for the Fleet aircraft carrier then being built. The new name was first used for an RN warship when given to a Sloop in 1776. It had previously been borne by a seaplane carrier in 1917 which was sold in 1931. In March 1942 the ship was 'adopted' by the civil community of Saddleworth, Yorkshire after a successful WARSHIP WEEK National Savings campaign.

Forget the internet, it is a swamp of garbage and misinformation. See if your library can get this book which is the best, most recent (over 28 years old!) book on the attack:


Buy it here for next to nothing:
