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: Tomić belonged to the first class of six Serbian pilots trained in France in 1912. In August 1914, he participated in the first aerial dogfight of the war, when he exchanged gunfire with an Austro-Hungarian plane over western Serbia. In the winter of 1915, during the Serbian Army's retreat across Albania to the Greek island of Corfu, he evacuated General Petar Bojović from Scutari by plane, delivered mail by air and transported the Serbian Government's gold and hard currency reserves from Niš to keep them from falling into enemy hands. Following the occupation of Serbia by the Central Powers, Tomić went to France and flew over the Western Front, where he had one confirmed kill. He returned to the Balkans in late 1916, conducted combat missions over Bulgarian-occupied Macedonia and shot down one enemy plane. Tomić continued flying after the war and became head of the Royal Yugoslav Air Force's pursuit squadron in Novi Sad. During World War II, he was captured by the Germans and detained as a prisoner of war. Tomić left Yugoslavia following the war and settled in the United States with his wife. He died in Chicago in 1962.
