Overview
The Twin Sisters are a pair of cannons used by Texas Military Forces during the Texas Revolution. They are among the most famous artillery in Texas military history with the "Come and Take It" cannon starting the revolution at the Battle of Gonzales and the Twin Sisters winning it at the Battle of San Jacinto. The Twin Sisters were also potentially used during the Mexican Invasions of 1842 and American Civil War.
Their disappearance and ensuing search efforts have fueled their notoriety, colloquially referred to as the "Texas Holy Grail."
History
Provenance
Nearly every aspect of the Twin Sisters is debated among historians, archaeologists, and treasure hunters including their design, type (iron or bronze), caliber (four or six pounder), foundry of fabrication (Hawkins and Tatum or Eagle Iron Works/Greenwood), origin of the "Twin Sisters" moniker, where they were used, and where they disappeared.
