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.
