Fort Armstrong (Illinois)
Fort Armstrong, was one of a chain of western frontier defenses which the United States erected after the War of 1812. It was located at the foot of Rock Island, in the Mississippi River near the present-day Quad Cities of Illinois and Iowa. It was five miles from the principal Sauk and Meskwaki village on the Rock River in Illinois. Of stone and timber construction, 300 feet square, the fort was begun in May 1816 and completed the following year and consisted of three large blockhouses, like the replica, on its prominent corners. In 1832, the U.S. Army used the fort as a military headquarters during the Black Hawk War. It was normally garrisoned by two companies of United States Army regulars. With the pacification of the Indian threat in Illinois, the U.S. Government ceased operations at Fort Armstrong and the U.S. Army abandoned the frontier fort in 1836.
Purpose
Fort Armstrong served five purposes of the United States. First, as a U.S. Army base of operations as mentioned earlier. Second, it was the regional headquarters location for the Indian Agent. The Indian Agent served in a liaison capacity between the regional Native American tribes and the United States government. Third, the regional interpreter who served both civilians and Soldiers at the request of both Americans and Native Americans. Fourth, the trade industry that thrived between civilians, U.S. Army Soldiers, and local Native Americans. Fifth, the U.S. Army surgeon was stationed there that really served as the regional hospital.Rock Island before construction
In 1805, when President Thomas Jefferson sent Lewis and Clark on their expedition into the Louisiana Territory, he also sent Lieutenant Zebulon Pike and Major Stephen H. Long up the Mississippi River to gather data and determine strategic sites for forts. Pike identified one site as the "big island;" Congress agreed with his recommendation, reserving the island for military use in 1809 and naming it Rock Island.The Sauk considered the island sacred:
Construction
This was to be the second US fort between St. Louis and Prairie du Chien, Wisconsin. The US wanted to establish a military presence to dissuade the French and English Canadians from encroaching upon the unorganized territory. After its losses at several forts during the War of 1812, the US Army wanted to increase its presence on the Mississippi frontier. The fort also would serve to protect American settlers within the area and to help control or remove the Sauk, a Native American people in the region. The Sauk disapproved of its construction; Black Hawk wrote in his memoir, "When we arrived we found that the troops had come to build a fort on Rock Island. This, in our opinion, was a contradiction to what we had done– 'to prepare for war in time of peace.' We did not object, however, to their building their fort on the island, but were very sorry."On May 10, 1816, soldiers arrived to begin construction of Fort Armstrong. It was named after John Armstrong, the Secretary of War under President James Madison. The army assigned 600 soldiers and 150 laborers to the project. After the construction was completed, fewer than 200 soldiers garrisoned the post. Between 1824 and 1836, the garrison was reduced to fewer than 100 troops. From 1840-1845 it served as a military depot, where the U.S. Army would keep war time supplies. one of the three buildings of Fort Armstrong was destroyed by fire in 1855. The account of the fire from the U.S. Army Quartermaster stationed there at the time described an unknown perpetrator with the ill intent of stealing kegs of black powder and keg parts for their own financial gain. The remaining two building were destroyed to make way for what would become the new fort of Rock Island Arsenal.
