Quincy Adams Gillmore was an American civil engineer, author, and a general in the Union Army during the American Civil War. He was noted for his actions in the Union victory at Fort Pulaski, where his modern rifled artillery readily pounded the fort's exterior stone walls, an action that essentially rendered stone fortifications obsolete. He earned an international reputation as an organizer of siege operations and helped revolutionize the use of naval gunnery.

Fort Pulaski National Monument is located on Cockspur Island between Savannah and Tybee Island, Georgia. It preserves Fort Pulaski, the place where the Union Army successfully tested rifled cannon in combat during the American Civil War in 1862, the success of which rendered brick fortifications obsolete. The fort was also used as a prisoner-of-war camp.
