Volume 6, Part 2: August 15-31, 1861

Volume 6, Part 2 covers the latter half of August 1861, following the death of Union General Nathaniel Lyon at the Battle of Wilson's Creek. Much of the discussion in this volume centers on Lyon's legacy, with numerous articles honoring his service and describing the arrangements for the return of his remains to Connecticut. At the same time, debate begins over responsibility for the Union defeat and Lyon's death, with criticism directed at the War Department and delays in sending reinforcements. Meanwhile, tensions in St. Louis continued as military authorities tightened control of the city, including the arrest of leading officials and increasing restrictions under the authority of Provost Marshal Justus McKinstry.

Military activity across Missouri also intensified. Skirmishes occurred in several regions of the state as Union Home Guards, federal troops, and Confederate-aligned forces maneuvered for control of strategic towns and transportation routes. Reports describe fighting in northern and southeastern Missouri, attacks on rail lines, and efforts by both sides to organize and reinforce their forces. Provisional Governor Hamilton R. Gamble called for tens of thousands of volunteers to restore order, while Union commanders-including Ulysses S. Grant-took steps to suppress secessionist activity. The month ended with Major General John C. Frémont declaring martial law across Missouri, marking another major escalation in the struggle for control of the state.
