The 1st Company of Sharpshooters of the 27th Michigan Infantry was also known as "Perrin's Sharpshooters" and they operated in direct connection with the 27th Michigan Infantry from their inception in 1864 until the end of the war. They were armed with the most destructive Infantry arm of the war, the "Spencer repeating rifle". They were so effective in actions with the 27th that the entire Regiment voted to all be armed with them and the whole Regiment be redesignated as "Sharpshooters". This vote was never recognized by the War Department.
