Georgia's oldest city is welcoming a truckload of historical treasures from the earlier period of U.S. history. Seventeen cannons that experts believe sank in a Georgia river during the American Revolution arrived by truck Wednesday at a Savannah museum that plans to put them on display during the Fourth of July weekend marking American's 250th birthday. Archaeologists say the big guns sat at the bottom of the Savannah River for nearly 240 years before they were discovered during a 2021 dredging project. The cannons spent years being cleaned and preserved at Texas A&M University before returning to Georgia.
