The Sharps rifles that had been shipped to Lawrence from New England became of immense value at this time, as the fear of them kept the enemy from a sudden attack. Blackmar, in his Life of Charles Robinson, says: "It was a strange spectacle, almost a comedy had it not been so near a tragedy, and in any case was certainly a travesty on free government, for the United States Senator Atchison to be commanding this singular horde, while Governor Shannon was hurrying other commands to the scene of war. There was no excuse for it all. The rescuers of Branson had left the town, and there was not a day in which Jones might not go through Lawrence unmolested in doing his duty. He actually did go to the town and return without being disturbed. Governor Shannon became alarmed first for the safety of the attacking Missourians, and second for the safety of Lawrence. He sent to Colonel Sumner, at Leavenworth, for United States troops, but Sumner would not come without orders from "Washington."

From the surrounding towns, Lawrence continued to receive reinforcements, who were usually surprised to find that the inhabitants were strictly on the defensive instead of the aggressive as reported by the pro-slavery men. Finally the citizens sent a delegation to the governor to acquaint him with the true situation. Being incredulous, he was persuaded to go to Lawrence to see for himself, and upon his arrival was amazed at the situation. The besiegers and besieged were brought into conference by him. The governor, Colonel Boone, of Westport, Missouri, Colonel Kearney, of Independence. Missouri, and General Strickler, of Kansas, were duly conducted to Lawrence and to the rooms of the committee of safety in the Free-State Hotel. Dr. Robinson and Colonel Lane conducted the negotiations on the part of the free-state men, as members of the committee of safety, and after both sides of the question had been discussed, the governor suggested that a treaty be drawn up and signed by the leaders, which was done. Blackmar, in his Life of Charles Robinson, says "it was an excellent way out of a dilemma, but here was another scene in the drama of spectacular government; the town of Lawrence in rebellion, treating with the Kansas militia, the latter commanded by officers living in Missouri."

The good will of the people of Lawrence and their genuine desire to settle the war was shown by the treaty. After it was signed, Robinson and Lane accompanied the governor to the camp of the militia, where Governor Shannon persuaded them to accept the treaty and withdraw. This was not easily accomplished, but the Missourians finally started for home.
