Forum:KB:Date of the liberation of Ackbar

I intend to write a comprehensive BtS paragraph on the exact dating of Star Tours: The Adventures Continue, but I need to know when exactly the liberation of Gial Ackbar took place. The article does say 1 BBY, but the statement is not sourced. Does anyone know where the 1 BBY figure comes from? --LelalMekha (talk) 00:17, February 2, 2013 (UTC)
