Sioux Falls in Minnehaha County, South Dakota — The American Midwest (Upper Plains)
The Amidon Affair
Amidon was a County Probate Judge, Treasurer and Commissioner appointed by Governor Jayne and the Territorial Legislature. When he and William failed to return home at sundown, Mrs. Amidon became alarmed and sought help from the Dakota Calvalry detachment in the village. A search was to no avail, but their bodies were found in the morning. Joseph died of a single bullet wound, William was riddled with arrows.
George B. Trumbo brought their bodies back to the village. Later, Sgt. Jesse Buel Watson, Company A, Dakota Cavalry, reported, we picked up the bodies and buried them in a cemetery (on what is now) North Duluth Avenue.
Two days later, orders came by courier from Governor William Jayne to abandon Sioux Falls and seek shelter at the Territorial Capitol at Yankton. Settlers and soldiers together hastily set out in a wagon train before sundown.
Following the settlers flight to Yankton, Sioux Falls remained abandoned until the establishment of Fort Dakota by federal troops in 1865, when settlement was resumed.
Joseph B Amidon was born in Connecticut in 1801. He came to Sioux Falls from Saint Paul, Minnesota, with his wife Mahala, son William and daughter Eliza, sometime before 1860.

3. The Pioneer Memorial
Honors the early settlers who faced the harsh and lonely prairie, the ferocity of the elements, and the uncertainty of their fate in this new land. Between 1856 when Sioux Falls City was platted and 1889 when South Dakota achieved statehood, they built homes, farms and businesses and planted their family roots in Minnehaha County. This Sioux quartzite obelisk was erected in their memory in 1949.
