Revolutionary War cannons debut at Savannah History Museum for America 250

A piece of Revolutionary War history that spent more than two centuries hidden underwater is now on display in Georgia's oldest city, just in time for America's 250th anniversary.

Nineteen cannons discovered at the bottom of the Savannah River were unveiled Thursday as a part of a new exhibit at the Savannah History Museum. The cannons spent nearly 240 years underwater.

"This is the largest discovery of 18th century artillery from a single Revolutionary War naval event," said Nora Fleming Lee, CEO of Coastal Heritage Society.
