The settlement of Blue Mounds was founded in 1828 by
Ebenezer Brigham on the south slope of the eastern mound of the Blue Mounds. In 1832, when word arrived that
Chief Black Hawk and his 1200
Sauk followers had crossed the
Mississippi River, it was decided to build a fort to protect the settlers. The fort was built a mile south of
Eastern Mound on the highest part of the open prairie, allowing for a commanding view of the open country for miles. Those who defended the fort were able to see to the east, south, and west, with the mound bounding the northern side of the fort. Word quickly arrived at the settlement of an engagement between
Black Hawk's group and the
Illinois militia on May 14, 1832. In what was to be called the
Battle of Stillman's Run, the Illinois militia were defeated by the Indians. This, along with the closeness of the
Ho-Chunk tribe, brought fear to the settlers, and they worked quickly to complete the fort in about two weeks. From May 20 to September 20, 1832, the settlers and miners joined General
Henry Dodge's Michigan Territory Militia during the
Black Hawk War.
James Aubrey was the first commander at the fort, but after he was killed by the Indians on June 6, his
first lieutenant,
Edward Beouchard, took command. He didn't command long before
Captain John Sherman succeeded him. ==Archaeology==
