More Attacks On the Fort. From our Regular Correspondent Sr. Group, Mryx., 11 oclock, p. ™.,0 October 3, 1862, To the Editor of the Pioneer. I have just had an interview with Capt. Ambrose Freeman, of the Frontier Cav alry, the company of mounted men raised in this town, who left Fort Abercrombie on Tuesday p. M. last. His company, with the citizens in the Fort, and one company of the Minnesota Third, who went up with Capt. Berger, were detailed as an escort for the women and children now on their way to this place. Since the last dispatches there have been three attacks on the Fort, the Indians being driven back each time with consid erable loss. Capt. Freeman and the train containing the women and children, with the escort, started on Tuesday last, and were followed all the way to Chippewa Station by the Indians. Each night they camped and threw up breast works, posted their pickets and exercised so much cau tion, that they were not attacked, and, when left by Capt. Freeman, yesterday, three miles this side of Chippewa Station, had not lost a single person. The ‘rin consists of some forty wagons, besides the escort of infantry and cavalry. They are expected here to-morrow evening, and preparations will be made to receive them and make them comfortable. After the arrival of Captain Berger the post was thoroughly fortified, and a large quantity (some three hundred bushels) of potatoes were dug for the use of those in garrison, and taken thither. There is great scarcity of provisions and ammuni tion in the Fort, and there is no forage for horses. To procure supplies of these rath er essential articles is part of Captain Freeman's business here. He will prob ably proceed at once to St. Paul, and re port to General Pope. A. Montgomery has just arrived from Forest City and Fair Haven, and reports all quiet in that quarter. Colonel Thomas left here this afternoon for Fort Ripley. Captain Freeman met that portion of the Wisconsin Twenty-fifth destined for Sauk Centre, some ten miles above Rich mond, to day. CO. of Otter Tail City, and his two sons, have also been taken by the Sioux, and that they (the Sioux) supplied themselves with large quantities of goods, the property of private traders, in transit to the Hudson Bay Company’s Territory. Regular communication with Fort Aber crombie will probably be opened in a week from this time, and the transporta tion of mails resumed by the Minnesota Stage Company. Whitefield, at Kandatta, is now the last white man settled on what two or three weeks since, was, for a frontier region, a thickly settled country. Kandatta is three miles above Sauk Centre, on the Red Ri ver Road. Capt. Barrett's Company has reached Fort Abercrombie. Capt. McCoy and his command are still at Sauk Centre. The mails are now regularly carried from Clear Water to Forest City. 0.
