Origins of the Ordnance Corps
The Ordnance Corps dates back to the early days of the American Revolution. In 1775, a Continental Congree committee, which included George Washington, convened to study the methods of arms and ammunition procurement and storage. As a result, Ezekiel Cheever was appointed as the Commissary General of the Artillery Stores, making him essentially the first Chief of Ordnance. In 1776, a Board of War and Ordnance was created, with the responsibility of issuing supplies to troops in the field. The next year, the first Ordnance powder magazine was established at Carlisle, Pennsylvania, followed shortly thereafter by the first arsenal and armory operations at Springfield, Massachusetts. Other arsenals and armories were also established at Harpers Ferry, Philadelphia, and Watertown, near Boston.
On May 14, 1812, the Ordnance Department was formally organized by Congress as part of the preparations for the second British war. The department assumed responsibility for arms and ammunition production, acquisition, distribution, and storage in a much broader geographical base than in the War for Independence
