During WWI, blockships were deliberately sunk in the smaller channels of the Scapa Flow in the Orkney Islands to protect British ships from attack. By the beginning of WWII, the defenses had fallen into disrepair and the blockships proved to be inadequate when HMS Royal Oak was sunk at anchor on October 14th, 1939. Taking advantage of high tide, the German submarine U-47 was able to navigate around the blockships, gain access to the Scapa Flow, and carry out two attack runs. Seven torpedoes were launched, three of which struck HMS Royal Oak. Within 15 minutes the HMS Royal Oak had sunk and the German U-boat had left the way it entered. Of the 1,208 officers and men aboard the HMS Royal Oak, 833 were killed.
In response to the attack, Winston Churchill ordered the construction of four permanent barriers to prevent further attacks. These barriers would also link together the chain of islands.
