Who Survived The Jedi Purge

Please post any known answers (with a source if possible). This does of course include Expanded Universe.

One question I would love to know is:

Did Yoda ever declared some sort of retreat signal for all Jedi to go into hiding?

Or did some (smart/scared) Jedi do this on their own?

Or did most (loyal-brave/dumb) make a last stand and die?

My 2 cents on the matter at hand...

SPOILER!!!!

Well in episode 3 the clone's will all be given the same mission at once. TO KILL THE JEDI!! Many will fall right away. Being slain by the troops they have been leading. The others will scatter across the galaxy like you mentioned some in hiding. Others trying to make a stand and failing over the next two decades between episode 3 and 4 as they are slowly hunted down by Darth Vader and his minions. Yoda will not have time I think to recall the Jedi. This will be the ultimate every man for himself gig!! There are several Jedi I would like to see survive. But it is much too early to debate upon.

This is just one take on the eradication of the Jedi order by the one dog in the stars...
