[Q]: Passage: On May 20, 1861, when the Civil War began, Indiana Governor Oliver P. Morton appointed Hackleman colonel of the 16th Indiana Volunteer Infantry of one-year volunteers. Hackleman and the 16th Indiana were sent to the Eastern Theater where they were engaged at the Battle of Ball's Bluff. On April 28, 1862 he was promoted to brigadier general of volunteers and ordered to report to Ulysses S. Grant in the Western Theater. Hackleman was assigned to command the 1st Brigade in the 2nd Division of the Army of the Tennessee. The 2nd Division, led by Thomas A. Davies, was temporarily attached to William S. Rosecrans' Army of the Mississippi stationed around Corinth, Mississippi. On October 3, the Confederate Army attacked Rosecrans. Early in the fighting the Confederates forced a gap between Davies and General Thomas J. McKean's divisions and the Union line began to fall back. At this point in the battle Hackleman attempted to rally his brigade and was shot through the neck. He was taken to the Tishomingo Hotel in Corinth where he lay dying from the mortal wound. His final words were: "I am dying, but I die for my country". His body was returned to his home in Rushville where he was buried. He was the only Indiana general to be killed in battle during the Civil War.

[Q]: Passage: The river rises in northwestern Wyoming in the Absaroka Range, on the Continental Divide in southwestern Park County. The river starts where the North Fork and the South Fork of the Yellowstone River converge. The North Fork, the larger of the two forks, flows from Younts Peak. The South Fork flows from the southern slopes of Thorofare Mountain. The Yellowstone River flows northward through Yellowstone National Park, feeding and draining Yellowstone Lake, then dropping over the Upper and Lower Yellowstone Falls at the head of the Grand Canyon of the Yellowstone within the confines of the park. After passing through the Black Canyon of the Yellowstone downstream of the Grand Canyon, the river flows northward into Montana between the northern Absaroka Range and the Gallatin Range in Paradise Valley. The river emerges from the mountains near the town of Livingston, where it turns eastward and northeastward, flowing across the northern Great Plains past the city of Billings.
