@wittmann:
It is funny, because I would associate these “pirate” ventures more with the 17th North Americas or later 19th century Civil War. But that is silly, as Merchant Shipping is big money and horrifically it still happens today!
A Cruiser nonetheless, was the Kormoran armed with 6inch guns too or was it one lucky shot from a smaller piece?
She was armed with 5.9’’ guns, 37mm tank guns, 20mm AA and 4 torpedo tubes. Plus several hundred mines.
From my reading the Australia cruiser did not give the Raider enough distance in attempt to discover the idenity of the unknown ship. The Raider attempt to pass itself of as a dutch ship with some sucess until over the radio the question was asked, "about secret code phrase.’
It was at that time the Germans raised the battle flag and got the first shots of the battle. The cruiser did not have all its guns ready for battle. Both ships ripped one another to pieces. With the Kormoran fired a torpedo which blew the cruiser up.
