In Fahrenheit 451, how does Montag escape from the city and where does he end up?

Montag and Faber try to confuse the Mechanical Hound’s
sense of smell. Montag makes it to the river and the scent is lost when he jumps in. He
floats down the river and the manhunt continues in the city. He floats downstream until
the next morning. He goes ashore and meets Granger and the other “book covers,” a group
determined to mentally record as much literature as they can. Granger offers Montag a
chemical which will change his body’s chemical signature and this will also throw the
Mechanical Hound off the trail. A war has broken out in the meantime and the city is
bombed to smithereens. This completes Montag’s escape. Presumably, now there is no one
left to chase him.
