# Oscar F. Jackson *Man lynched in Wright County, Minnesota, on April 25, 1859, after a jury had acquitted him* Oscar F. Jackson was hanged by a mob in Wright County, [[Minnesota]], on April 25, 1859. A jury had acquitted him three weeks earlier. These dates come from a composite account in the project's dossier, which draws on contemporaneous newspaper reporting.[^1] The project's at-issue record adds three points. Before the killing, a justice of the [[Minnesota Supreme Court]] had issued two writs ordering Jackson released. The [[sheriff]] had promised him protection. No one was ever convicted for the killing.[^2] The dossier account places these events within the [[Wright County War]]. It dates the events as follows:[^1] - Henry A. Wallace was found murdered in September 1858. - Jackson was arrested in October 1858. - A jury acquitted him on April 3, 1859. - He was re-arrested on a theft charge on April 8. - Justice [[Isaac Atwater]] issued writs of habeas corpus around April 11–13. - A mob besieged the Holdship farmstead on April 24. - Jackson was lynched on April 25. - Governor Sibley issued a $500 reward proclamation on April 29. That reconstruction is secondary and is cited to Wikipedia. Its dates are given here as the account's own, not as independently verified.[^1] The official paper record is thin. The Minnesota Historical Society's holdings of [[Wright County District Court]] records begin in 1881, and the 1859 case file does not survive.[^3] A folder in the Governor Sibley records, *Letters Received, 1859: Wright County Affair* (box 154.J.14.1B), has been located, but its contents have not been retrieved.[^4] ## Who The record identifies Jackson only through the events of 1858–1859. He was arrested in October 1858, acquitted by a jury on April 3, 1859, re-arrested on April 8, 1859, and lynched on April 25, 1859.[^1] The cited sources give no other biographical detail.[^1][^2] Two officials appear in the account by name: - Justice Isaac Atwater, who issued the writs of habeas corpus.[^1] - Governor Sibley, who issued the reward proclamation and whose 1859 records hold the located folder.[^1][^4] ## What The record sets the outputs of the state's institutions in sequence:[^1][^2] 1. A jury verdict of acquittal. 2. Judicial writs ordering release. 3. The sheriff's promise of protection. 4. A mob hanging. 5. A gubernatorial reward proclamation. The record ends with no conviction for the killing.[^2] The court file for the case does not survive in the state archive.[^3] ## When - September 1858: Henry A. Wallace found murdered, per the composite dossier account.[^1] - October 1858: Jackson arrested, per the same account.[^1] - April 3, 1859: jury acquittal.[^1] - April 8, 1859: re-arrest on a theft charge.[^1] - circa April 11–13, 1859: writs of habeas corpus issued by Justice Isaac Atwater.[^1] - April 24, 1859: mob besieges the Holdship farmstead.[^1] - April 25, 1859: Jackson hanged in Wright County.[^1][^2] - April 29, 1859: Governor Sibley's $500 reward proclamation.[^1] ## Where The killing took place in Wright County, Minnesota.[^2] The composite account places the preceding siege at the Holdship farmstead.[^1] ## Why The record does not establish the mob's reasons. Neither the at-issue record nor the dossier account states them.[^1][^2] ## How According to the dossier account, a mob besieged the Holdship farmstead on April 24, 1859, and lynched Jackson the next day.[^1] The at-issue record states that the sheriff had promised Jackson protection before the hanging.[^2] ## How much The composite account records a reward proclamation of $500, issued by Governor Sibley on April 29, 1859.[^1] ## How many - Writs: the at-issue record states that two writs ordering Jackson's release were issued. The dossier account refers to the writs in the plural without giving a number.[^1][^2] - Convictions: the at-issue record states that no one was ever convicted for the killing.[^2] ## In the at-issue record The project's at-issue record lists the killing as entry AI-Humphrey-010. The entry is ranked 10 in the "Humphrey" package, under the section *The Waverly Promise & the Boundary County Edition*.[^2] It sets Jackson's acquittal, the two writs and the sheriff's promise against the hanging and the absence of any conviction.[^2] The entry is anchored to an April 2025 White House presidential action on law enforcement.[^5] The project's stated rationale for the anchor is that an enforcement apparatus producing orders but no protection is the failure the order addresses. That rationale is the project's framing, not a finding of the order.[^2] ## Notes [^1]: Project dossier, *Insurrection_Doctrine_5000_STEELMAN_2026-09-02.md*, note 1, citing Wikipedia, *Wright County War* — composite account from contemporaneous newspaper reporting: Wallace murder (September 1858), arrest (October 1858), acquittal (April 3, 1859), re-arrest (April 8), Atwater writs (c.
