Sauron was a mystery because Sauron was a coward. He only personally confronted an opponent twice in all the ages of Middle-Earth, and both times were well against his better judgment and will. His battle with Huan at Tol-im-Gaurhoth during the Quest for the Silmaril and the fight with Elendil at the end of the War of the Last Alliance were both cases of Sauron being pushed against the wall with no way to run.
When he did have the option of either escape or simpering surrender when Ar-Pharazon captured him, he took it. Of course, that surrender and captivity served a longer-range purpose (the completion of the Rot of Numenor).
He ran at the end of the First Age rather than submit to Eonwe (forgive my lack of diacritics) and return to Valinor to be judged. He ran after Huan gave him a drubbing at Tol-im-Gaurhoth. He ran when Gandalf approached Dol Guldur in the middle of the Third Age. Sauron was a wuss.
