John Henry Kagi

The Mayhew Cabin was the first site in Nebraska recognized by the National Park Service as it was used as part of the Underground Railroad.

By 1856, Kagi went south to join the abolitionists working to make Kansas a free state, serving under General James H.

He was captured a month later by United States Army troops along with 100 men of Col. Harvey's company, who had just attacked Hickory Point.

On May 8, 1858, in a black church in Chatham, Ontario, they adopted Brown's "Provisional Constitution and Ordinances for the people of the United States", and Kagi was named Secretary of War.

[7] Kagi and Brown returned with their men to Kansas, where they lived in a reinforced cabin on Little Sugar Creek, near Mound City.

[7][9] While they planned the raid on Harper's Ferry, Kagi acted as the business agent of the Brown's group, buying and storing weapons in Chambersburg, Pennsylvania.

On August 19, Brown (using the name Isaac Smith) and Kagi met with Frederick Douglass and Shields Green at an abandoned quarry outside of Chambersburg to discuss the raid.

Kagi was killed by militia forces during the Harper's Ferry raid as he tried to escape across the Shenandoah River from Hall's Rifle Works.
