Sauron's Super Army?

[Mornorngûr]

Apart from the practical reason that the Nine had already been dispensed by that point in time and there were no Great Rings remaining for him to give out, I think that Sauron simply did not want most of the Númenoréans to survive.

I thought that Sauron actually held 'The Nine'? After the Men he gave them to were corrupted, did he not take them back? or did the Nazgul still have them?.

Actually I have just been doing some research and it is clear to me that Sauron actually held them and therefore could re-distribute them if he wished.
