I was a German surface raider, known for my speed and success in disrupting Allied convoys during World War II. My career was relatively short, but I had a significant impact on naval operations. I was involved in the sinking of multiple Allied merchant ships and even a few warships. What am I?

1. I was nicknamed the 'Sea Devil'.
2. My operations mainly took place in the Atlantic and Indian Oceans.
3. I was equipped with heavy guns and torpedoes.
4. My eventual sinking was the result of a major naval pursuit.
