The Maynard carbine was a breech-loaded carbine used by cavalry in the American Civil War. The First Model was manufactured between 1858 and 1859. About 5,000 were made. In United States service it was distributed to the 9th Pennsylvania and 1st Wisconsin cavalry regiments, United States Marines aboard the USS Saratoga and the United States Revenue Cutter Service. About 3,000 Maynard carbines were in Confederate hands during the war; 5,000 in .35 caliber were purchased by Florida, 650 in .50 by Georgia, and 325 in .50 and 300 in .35 by Mississippi. Around 800 were purchased by militias in South Carolina and Louisiana. The Second Model or Model 1863 was manufactured between 1863 and 1865. Over 20,000 were made. This model lacked the tape primer and stock patchbox, and was used by the 9th and 11th Indiana cavalry regiments and 11th Regiment Tennessee Volunteer Cavalry, among others. The Maynard had a good reputation for long-range accuracy, and Confederate sharpshooters made extensive use of it, especially during the Siege of Charleston.
It was highly praised by the soldiers – Private Toby of the 1st Mississippi Infantry stated that it was "warranted to shoot twelve times a minute, and carry a ball effectually 1600 yards. Nothing to do with Maynard rifle but load her up, turn her North, and pull trigger; if twenty of them don't clean out all Yankeedom, then I'm a liar, that's all."
