Quincy Adams Gillmore

Quincy Adams Gillmore (February 28, 1825 – April 7, 1888) 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.
