Armament


The 17th Maine was an 1862, Army of the Potomac, three-year regiment, that greatly increased the number of men under arms in the federal army. As with many of these volunteers, initially, there were not enough Model 1861 Springfield Rifles to go around so they were instead issued imported British Pattern 1853 rifles.[43] These were the standard rifle for the British army having performed well in the Crimean War. The Enfield was a .577 calibre Minié-type muzzle-loading rifled musket. It was used by both armies and was the second most widely used infantry weapon in the Union forces.[44]
At Gettysburg, on the evening of July 3, General Birney wanted to standardize the weapons in his division.[10] That evening, he had the 17th and other Enfield-equipped units in his command exchange their arms for the standard muzzle-loading rifled musket of the Union Army, the Springfield Model 1861 Rifled Musket. It fired a .58 inch Minie Ball. and came with a square socket bayonet. They would carry their Springfields until their end of service.[42]
Casualties and total strength
The 17th Maine enrolled 1,371 men during its existence.[3] It lost 12 officers and 116 enlisted men killed in action or died of wounds received in battle and an additional 4 officers and 159 enlisted men died of disease.[7] 31 men died in Confederate prisons.[42] Total fatalities for the regiment were 370.[10][3]
