Harney also informed Price that several clauses in Missouri's recently enacted "Military Bill" would have to be modified to remove potential conflicts with the federal government's legal authority.
The truce drew the immediate ire of a wide variety of Missouri Unionists (including the politically powerful Congressman Frank Blair), who lobbied President Lincoln and the War Department to have Harney relieved of command.
In the face of reports of abuses against Missouri Unionists, and continued negotiations between Governor Jackson and the Confederate Government, Lincoln approved Harney's replacement as commander of the Western District by newly promoted Brigadier General Nathaniel Lyon.
On June 11 Missouri Governor Claiborne Fox Jackson held a last-ditch meeting at the Planter's House Hotel in St. Louis to delay open conflict in the State.
During the meeting, Lyon angrily refused Price's requests to limit federal forces to the metropolitan St. Louis area, and to disband "Home Guard" companies established by Missouri Unionists.
