PROTECTION OF THE SOUTHERN FRONTIER.

On the 29th of August I received a commission from the governor of the state, instructing and directing me to take command of the Blue Earth country, extending from New Ulm to the north line of Iowa, embracing the then western and southwestern frontier of the state. My powers were general—to raise troops, commission officers, subsist upon the country, and generally to do what in my judgment was best for the protection of this frontier. Under these powers I located my headquarters at South Bend, being the extreme southern point of the Minnesota river, thirty miles below New Ulm, four from Mankato, and about fifty from the Iowa line. Here I maintained a guard of about eighty men. We threw up some small intrenchments, but nothing worthy of mention. Enough citizens of New Ulm had returned home to form two companies at that point. Company "E," of the Ninth Regiment, under Capt. Jerome E. Dane, was stationed at Crisp's farm, about half way between New Ulm and South Bend. Col. John R. Jones of Chatfield collected about three hundred men, and reported to me at Garden City. They were organized into companies under Captains N. P. Colburn and Post, and many of them were stationed at Garden City, where they erected a serviceable fort of saw-logs. Others of this command were stationed at points along the Blue Earth river. Capt. Cornelius F. Buck of Winona raised a company of fifty-three men, all mounted, and started west. They reached Winnebago City, in the county of Faribault, on the 7th of September, where they reported to me, and were stationed at Chain Lakes, about twenty miles west of Winnebago City, and twenty of this company were afterwards sent to Madelia. A stockade was erected by this company at Martin Lake. In the latter part of August Capt. A. J. Edgerton of Company "B," Tenth Regiment, arrived at South Bend, and having made his report, was stationed at the Winnebago agency, to keep watch on those Indians and cover Mankato from that direction. About the same time Company "F," of the Eighth Regiment, under Capt. L. Aldrich, reported, and was stationed at New Ulm. E. St. Julien Cox, who had previously reinforced me at New Ulm, was commissioned a captain, and put in command of a force which was stationed at Madelia, in Watonwan county, where they erected quite an artistic fortification of logs, with bastions. While there an attack was made upon some citizens who had ventured beyond the safe limits, and several whites were killed.

It will be seen by the above statement that almost immediately after the evacuation of New Ulm, on the 25th of August, the most exposed part of the southern frontier was occupied by quite a strong force. I did not expect that any serious incursions would be made along this line, but the state of alarm and panic that prevailed among the people rendered it necessary to establish this cordon of military posts to prevent an exodus of the inhabitants. No one who has not gone through the ordeal of an Indian insurrection can form any idea of the terrible apprehension that takes possession of a defenseless and noncombatant population under such circumstances. There is an element of mystery and uncertainty about the magnitude and movements of this enemy, and a certainty of his brutality, that inspires terror. The first notice of his approach is the crack of his rifle, and no one with experience of such struggles ever blames the timidity of citizens in exposed positions when assailed by these savages. I think, all things being considered, the people generally behaved very well. If a map of the state is consulted, taking New Ulm as the most northern point on the Minnesota river, it will be seen that the line of my posts covered the frontier from that point down the river to South Bend, and up the Blue Earth, southerly, to Winnebago City, and thence to the Iowa line. These stations were about sixteen miles apart, with two advanced posts, at Madelia and Chain Lakes, to the westward. A system of couriers was established, starting from each end of the cordon every morning, with dispatches from the commanding officer to headquarters, stopping at every station for an indorsement of what was going on, so I knew every day what had happened at every point on my line. By this means, the frontier population was pacified, and no general exodus took place.

In September Major General Pope was ordered to Minnesota to conduct the Indian war. He made his headquarters at St. Paul, and by his high rank took command of all operations, though not exerting any visible influence on them, the fact being that all imminent danger had been overcome by the state and its citizens before his arrival. In the latter part of September the citizen troops under my command were anxious to return to their homes, and on presentation of the situation to General Pope, he ordered into the state a new regiment just mustered into the service in Wisconsin—the Twenty-fifth—commanded by Col. M. Montgomery, who was ordered to relieve me. He appeared at South Bend on the 1st of October, and after having fully informed him of what had transpired, and given him my views as to the future, I turned my command over to him in the following order: I give it, as it succinctly presents the situation of affairs at the time.

"HEADQUARTERS INDIAN EXPEDITION
SOUTHERN FRONTIER,
"SOUTH BEND, October 5, 1862.

To the Soldiers and Citizens who have been, and are now engaged in the defense of the Southern Frontier:

"On the eighteenth day of August last your frontier was invaded by the Indians. You promptly rallied for its defense. You checked the advance of the enemy and defeated him in two severe battles at New Ulm. You have held a line of frontier posts extending over a distance of one hundred miles. You have erected six substantial fortifications, and other defensive works of less magnitude. You have dispersed marauding bands of savages that have hung upon your lines. You have been uniformly brave, vigilant and obedient to orders. By your efforts, the war has been confined to the border; without them, it would have penetrated into the heart of the state.

"Major General Pope has assumed command of the Northwest, and will control future operations. He promises a vigorous prosecution of the war. Five companies of the Twenty-fifth Wisconsin Regiment and five hundred cavalry from Iowa are ordered into the region now held by you, and will supply the places of those whose terms of enlistment shortly expire. The department of the southern frontier, which I have had the honor to command, will, from the date of this order, be under the command of Colonel M. Montgomery of the Twenty-fifth Wisconsin, whom I take pleasure in introducing to the troops and citizens of that department as a soldier and a man to whom they may confide their interests and the safety of their country, with every assurance that they will be protected and defended.

"Pressing public duties of a civil nature demand my absence temporarily from the border. The intimate and agreeable relations we have sustained toward each other, our union in danger and adventure, cause me regret in leaving you, but will hasten my return.

"CHAS. E. FLANDRAU,
"Colonel Commanding Southern Frontier."
