James Henry Lane had a significant impact on Kansas history and is one of Constitution Hall’s more colorful characters. He was part of a large antislavery delegation that marched into Lecompton to protest the convening of the proslavery Lecompton Constitutional Convention in the fall of 1857. The nation’s eyes were fixed on this site, waiting to see what kind of constitution would be drafted and w

hether Kansas would join the Union as a free or slave state. At this National Historic Landmark you will learn more about Jim Lane, the proslavery and free-state forces in the area, and other stories of territorial Kansas.

This flag was captured by free state troops on August 15th, 1856, at the battle of Fort Saunders, near the present day town of Lone Star, in Douglas County. It flew at the proslavery stronghold throughout the summer of 1856, until the fort was captured and destroyed.

The massive banner bears the slogan "ENFORCE THE LAWS", referring to the 1855 Laws of Kansas Territory, often called the "Bogus Laws" by antislavery Kansans, who considered the blatantly bias legal code to be illegitimate on account of the one-sided legislature that passed them.

After their victory at Fort Franklin on August 12th, 1856, Free State forces regrouped with the newly arrived reinforcements from Jim Lane's "Army of the North", and prepared to make an attack on the largest of the proslavery strongholds in Douglas County, Fort Saunders.

Fort Saunders was a fortified two story blockhouse in the settlement known as Treadwell, surrounded by earthworks and a large encampment of proslavery troops. It was named after proslavery settler and Captain in the Territorial Militia, James Saunders, who owned the claim where the fort stood. Colonel B.F. Treadwell commanded the post, which was manned by about 100 proslavery militiamen at the time.

In the afternoon of August 15th, 1856, several hundred antislavery troops under the overall command of James H. Lane set off for Treadwell. They approached the fort from three different directions in hopes of capturing its defenders like they had at Franklin. Upon seeing the much larger advancing enemy exchange gunfire with his pickets, Col. Treadwell ordered the immediate evacuation of the post and its contents, and led his men to the safety of the Territorial Capital in Lecompton. Lane's men rushed the earthworks, only to find it empty, aside from one enslaved African American boy, who was left by the retreating enemy.

Unable to locate the whereabouts of Treadwell's force, the free state men then loaded up their wagons with the newly captured tents, muskets, ammunition, food, and reclaimed loot found to be originally stolen during the Sacking of Lawrence, and burned the fort to the ground.

In August 1856, after a summer of depredations by proslavery forces, antislavery Kansans in and around Lawrence reached a breaking point. With Jim Lane's "Army of the North" arriving in the Territory, bringing much needed relief and reinforcements, the Free State faction decided to take the offensive in what is called the "August War".

Since the Sacking of Lawrence in May, proslavery militias had been building up several fortified positions across Douglas County to keep Lawrence in check. The nearest one to Lawrence was Fort Franklin, in the settlement of Franklin, only 3 miles southeast of town. It had been the HQ of the proslavery army during the Wakarusa War last fall, and had already defended against one free state assault back in June.

On August 12th, 81 free state troops made a nighttime attack on Fort Franklin, this time capturing it after Capt. Thomas Bickerton suggested pushing a flaming wagon of hay up to the fort's walls. Its defenders surrendered, and the free state troops captured dozens of US muskets and the famed "Old Sacramento" cannon that had demolished the Free State hotel in May, proving to be an important victory by the Free State faction.

171 years ago today, on August 7, 1855, the Proslavery Kansas Territorial Legislature met in joint session at the Shawnee Manual Labor School in Johnson County to pick a territorial capital location:

It took a total of three seperate votes before the legislature eventually decided on Lecompton as the new capital. The results of those votes were:

The initial vote:
Leavenworth 6 One Hundred and Ten 1
Lawrence 2 Kickapoo 2
St. Bernard 12 Lecompton 9
Tecumseh 3 Whitehead 2
Douglas 2

Since no town got a majority, a second vote was held:
Tecumseh 5 St. Bernard 13
Lecompton 19 Lawrence 1

Still lacking a majority, a third vote was held:
Tecumseh 2
St. Bernard 11
Lecompton 25

On the Lecompton Constitution issue, US Senator Stephen A. Douglas from Illinois would openly defy fellow Democrat and United States President James Buchanan, as well as his Southern supporters in Congress, by strongly denouncing the fraudulent proslavery Lecompton Constitution’s attempt in 1858 to admit Kansas as the next slave state.

Regarding passing the Lecompton Constitution, Douglas is quoted as saying: “You do, and it will lead directly to civil war! I warned the anti-Lecompton Democrats of the North that the President intended to put the knife to the throat of every man who dared to think for himself on this question and carry out principles in good faith. God forbid, I said that I ever surrender my right to differ from a President of the United States for my own choice. I am not a tool of any President!”
