When the Civil War began in the spring of 1861, young men in Minnesota responded enthusiastically to Abraham Lincoln's call for volunteers.
By August 1862, all or parts of the First through Tenth Minnesota Regiments had been organized. Some of these regiments had been sent to do battle with confederates in the east or south -- but not all the units had been deployed.
So when Dakota Indians launched their war against settlers and soldiers on Aug. 18, 1862, quite a number of troops, many of them new recruits, were still in Minnesota.
Word of the attacks reached Fort Snelling and St. Paul the next day, and a military response was organized, with Col. Henry Sibley commanding. Some soldiers, such as those in Company B, Fifth Minnesota Regiment, were already in the troubled area, being stationed at Fort Ridgely.
But because other soldiers were not available in the immediate area where fighting was taking place and could not rapidly get there, militia units from the area were quickly raised. These militia units proceeded primarily to the assistance of New Ulm, which had called for help.
The battles in Minnesota in 1862 between the Dakota and soldiers and militia were not trivial affairs. In fact, in one battle, at Redwood Ferry on Aug. 18, a single Minnesota company saw more soldiers killed in action than did any company of Minnesota troops in any single battle of the Civil War.
This was Company B of the Fifth Minnesota, which lost 24 soldiers killed that day, including the commander, Capt. John Marsh, and his interpreter, Peter Quinn. It was half the force present at the battle.
The company with the second-highest number of Minnesota soldiers killed in a single battle was Company A of the famed First Minnesota Regiment. At Gettysburg on July 2 and 3, 1863, about 15 soldiers of Company A were killed or mortally wounded.
