What was Turkey's role in World War 2?

Turkey entered the second world war symbolically on the side of the allied forces, during the last few official days of the war. Turkey did not participate on any active war front during this war. The reason, if I am not mistaken, was to be identified with the winning side and somewhat erase the losing image left from the first world war. I am not sure if it is available in English, but there is a 3 volume set of books called as "ikinci adam" (translation: second man), which gives a detailed life story of Ismet Inonu, who was the president and the prime minister of Turkey at that time and there was a good section about this subject.
