Volume 7: September 1861

Volume 7 covers September 1861, a month marked by controversy over Major General John C. Fremont's declaration of martial law in Missouri. Much of the discussion centers on the provisions of the order, particularly those related to the confiscation of property and the emancipation of slaves belonging to rebels. The measure sparked widespread debate, prompting President Abraham Lincoln to modify key provisions and limit its scope. Meanwhile, political tensions within the Union command intensified as disagreements arose among federal officers and civilian leaders, including a public dispute between Fremont and Congressman Frank P. Blair Jr. Investigations by representatives of Lincoln's administration further fueled speculation about Fremont's leadership of the Western Department.

Military operations continued throughout the region during the month. Confederate and Missouri State Guard forces carried out raids and attacks on transportation lines, while Union forces maneuvered to secure strategic locations across the state. Engagements included the Action at Blue Mills Landing and the Battle of Lexington, both significant events in the struggle for control of Missouri. The volume also documents broader developments in the western theater, including Confederate moves into Kentucky and federal responses along the Mississippi River, reflecting the growing scale of the conflict beyond Missouri's borders.
