The twin sisters were two cannons graciously manufactured and donated to the cause of Texas liberty from the people of Cincinnati.  They served Texas well at the Battle of San Jacinto and played a key role in Texas independence.  You can see these great guns of liberty at....wait minute...no you can't.  We've lost them.  Where could they be?  Theories abound, but evidence is thin.  Some say they are buried by a bayou in Houston.  Some say they are in the bayou.  Some say they're in Austin somewhere.  Some think they were sold for scrap.  Nobody knows.  Listen to the latest episode of Wise About Texas and form your own opinion, and maybe start your own search for two of the most important artifacts in Texas history...the Twin Sisters.
