to broach those points. Carroll questioned Scott about the feasibility of using the Tennessee and Cumberland rivers for a Union invasion of the South. Scott provided Carroll with technical navigation details. Based on this information, Carroll wrote a memorandum to Assistant Secretary of War Thomas A. Scott and Attorney General Edward Bates in late November 1861, advocating that the combined army-navy forces change their invasion route from the Mississippi to the Tennessee and Cumberland rivers. Meanwhile, in St. Louis, Major General Henry W. Halleck was planning the same movement without Lincoln's knowledge. Upon learning that Confederates were possibly sending reinforcements west from Virginia, Halleck ordered Brigadier General Ulysses S. Grant and Flag Officer Andrew Hull Foote to immediately move on Fort Henry and Fort Donelson on the Tennessee and Cumberland rivers in a telegram dated January 30. Scott was dispatched to the Midwest to mobilize reinforcements for Halleck on the night of January 29. On February 6, Fort Henry fell to Foote's gunboats and on February 13, Fort Donelson fell to Grant's and Foote's combined forces. These comprised the first two "real victories" of the Civil War for the Union, as Gen. William Sherman wrote later. At the time Carroll's role in the effort was kept secret. Immediately following the war, she gave credit for the plan to Capt. Charles Scott in a letter printed in a leading Washington newspaper. Years later, Assistant Secretary of War Scott and Senator Wade testified to her critical role before Congress. During the remainder of the war, Carroll worked with Lincoln on issues pertaining to emancipation and colonization of American slaves. She and Aaron Columbus Burr lobbied him to establish a colony of freedmen in British Honduras, today Belize. Although Carroll had freed her own slaves, she lobbied Lincoln against issuing the Emancipation Proclamation. She feared that this action would cost the support of Southern Unionists and resistance to the Union would be stiffened. But, she wrote that Lincoln did have the constitutional right to free the slaves as a temporary war measure under his power as commander-in-chief, since the proclamation would help cripple the organized forces of the rebellion. Yet the measure was not a transfer of title and would have to be suspended once the war emergency ended. To free the slaves required a constitutional amendment. Postwar life and death In the postwar years, Carroll traveled with Lemuel Evans to report on
