What do you thinkmthose animals who can remember the rebellion would "pass on" to the younger animals about it?

I think the "truth" about the rebellion would change over the years. Stories would have to conform with Napoleon's version because the animals were afraid to say anything different.

Many animals had been born to whom the Rebellion was only a dim tradition, passed on by word of mouth, and others had been bought who had never heard mention of such a thing before their arrival.
