Because of its position on the outskirts of the white settlement, Fort Abercrombie was particularly vulnerable to Indian attacks, and during the Minnesota uprising of 1862 was besieged for five weeks by the hostile Sioux. The first attack, September 3, was repulsed with the loss of one man. At the close of this encounter the defenders discovered that only 350 rounds of rifle ammunition remained--- a supply had been ordered in the spring but had not arrived. The ingenuity of the garrison was exercised; canister shells for the 12-pound howitzers contained balls which fitted the rifles, so the women in the fort were put to work opening the canisters. The makeshift ammunition served its purpose well. The fort had no stockade; consequently, after the first attack, the defenders threw up around the entire fort a cordwood breastwork 8 ft. high. In the meantime messengers had slipped through the Indian lines to summon aid from Fort Snelling at Minneapolis. On September 6 a force estimated at 400 warriors again attacked the fort, but was driven back after a long fight in which two soldiers were killed and many wounded. The Indians made no more determined attacks on the fort, but continually harassed the beleaguered settlers with desultory sniping until the arrival of a detachment of 350 infantrymen from Fort Snelling relieved the garrison September 23. In November of the same year 10 acres of the fort reserve were enclosed by a heavy oak-log stockade with blockhouses at three corners, and about the same time a larger garrison was stationed at Abercrombie. It was from this enlarged post that the Sibley expedition set forth to punish the Sioux the following summer (_see_ HISTORY). The enlarged garrison was maintained until the abandonment of the fort in 1877. During the 1870's Fort Abercrombie was the point from which trails led W. to Forts Totten, Ransom, Wadsworth, and Garry, and many a train of home seekers or gold seekers spent a few days there before embarking on the hazardous trip through Dakota. Fort Abercrombie in 1870 was the scene of a treaty between the Chippewa and Sioux, concluded through the influence of Father J. B. Genin, a Roman Catholic priest. After this treaty the eastern part of the Territory was comparatively free from fear of Indian attacks. FORT ABERCROMBIE STATE PARK, on the eastern edge of the town, preserves 7 acres of the original 7 sq. m. of military reservation. The park lies along the river, and its natural beauty makes it a pleasant recreation center. An old cabin in the park houses a collection of early-day relics. Nearby stands a Red River oxcart whose wooden wheels once creaked over the old river trail before the days of railroads and highways.
