The Only One He Ever Feared

So we all know that one cannot disapparate or apparate inside 
Hogwarts or the Ministry. Well I was a little confused at the battle 
between Voldemort and Dumbledore.....It says in the book 
that "Voldemort was standing on the plinth in the middle of the pool 
where so recently the five statues had stood." Then it goes on to 
say " Then he was gone." Ok what happen there? This is the same pool 
where Harry himself took the portkey back to Hogwarts as instructed 
by Dumbledore. Did Voldemort take the portkey? It seems to me that 
only Fudge and Dumbledore knew of that porkey's location so how would 
the V-man know where it was? Because to me it sounded like all the 
statues had to be removed from that pool before that portkey could be 
used and that the statues came to life to help Dumbledore by so 
doing making the portkey readily available. I know V-man has quite a few 
informants within the Ministry but this was something I wasn't sure 
of..if he disapparated or if he used to portkey to escape.....and 
one last question .....why didn't Voldemort just use one of the 3 
unforgiveable curses on Dumbledore? Is he protected from this curse?
