There is a line in the movie The Alamo by John Wayne's character Colonel Crockett talking to his men:
Davy Crockett: First, the young lady and I will take a pasear. Gather up your possibles and I'll meet up with you later.
He then leaves with the young lady, before sending her off and coming back to join his band to march to the Alamo. Possible as noun appears to mean "possibiliy", according to Oxford Online Dictionaries. But what does it mean here? Judging from the context, my hunch is that Crockett here is telling others to gather their things/belongings, but I can't find this meaning under possible.
