The Rocket Battalion of Artillery (General Barry's), better known as the New York Rocket Battalion was an artillery battalion organized in the state of New York for service in the Union Army during the American Civil War.
The battalion was organized at Albany, December 5, 1861, and there mustered in the United States service for three years, December 6 and 7, 1861. The three companies recruited originally - Ransom's, Lee's and Sauer's - were consolidated into two companies on December 5 and the battalion, commanded by Maj. Thomas W. Lion, left the state on December 9.
It served at and near Washington, D. C., from December 1861, and in North Carolina, (2nd Brigade, 2nd Division, Dept. of North Carolina), from May 1862 until February 11, 1863, when the battalion organization was discontinued. The two companies, A and B, were designated the 23rd and 24th batteries of Light Artillery, having served provisionally as such from November 1, 1862. The loss and engagements of the battalion are included in the record of the batteries into which its two companies were converted.
During its months of service, the Rocket Battalion used eight breechloading cannon designed to fire Hale rockets. These were developed by Major Lions himself, and presented to President Lincoln shortly after the Battle of Bull Run in July 1861. They proved very unreliable during tests and in combat, so after the battalion was disbanded, each battery received regular M1857 12-pounder Napoleon's instead.
