Visit Lewis and Clark National Historical Park and discover one of the most fascinating pieces of technology carried by the Corps of Discovery: the Girandoni air r***e. Unlike anything many people had seen before, this repeating air r***e could fire up to 30 shots on a single charge, which was an incredible feat for the early 1800s. As the Corps traveled west, demonstrations of the r***e amazed the many communities they encountered. Invented by Bartolomeo Girandoni and later used by the Austrian Army, the r***e operated without gunpowder. Instead, air was pumped by hand into a reservoir attached to the weapon. Preparing the r***e required serious effort—about 1,500 strokes of a hand pump to fill its air reservoir. Today, only a small number of Girandoni r***es remain, and one is on display at the Fort Clatsop visitor center museum. Stop by and see this remarkable piece of history that was part of the Corps of Discovery.
