During the war of Independence, an extremist leader was arrested and was sentenced to be hanged to death. On the day before his hanging, he requested the jail authorities to take him to a temple to say his last prayers.
     There he received a chit from his followers which read as follows:

" Sir, we have planned to rescue you from the jail today night. We need to know your room number and the time when the securities will change their shift. Please write the details on the temple wall.

QUICK

66 58 82 94 78

DO NOT FORGET

92 70   72 70 60   88 70 64 86 90 60 "

He went out and scribbled these numbers on the temple wall using a charcoal piece..

64 70 70 74   72 70   46

60 82 74 90   90 82 86 84 60   60 84 82 64 60 50   68 74

The police thought he was mad and took him back to the jail. What does those numbers mean? Can you find them?
