1. George McClellan was a U.S. Army engineer, railroad president and politician who served as a major general during the Civil War. ... In 1862, McClellan's Peninsula Campaign unraveled after the Seven Days Battles, and he also failed to decisively defeat Robert E. Lee's Confederate Army at the Battle of Antietam.

Because of old age and infirmities he retired from the army in 1861, and he died at his beloved West Point in 1866.

3. John Pope was a career United States Army officer and Union general in the American Civil War. He had a brief stint in the Western Theater, but he is best known for his defeat at the Second Battle of Bull Run in the East. Pope was a graduate of the United States Military Academy in 1842.

Vital or civil registration is the system by which a government records the vital events of its citizens and residents. ... In contrast to censuses, which collect information on every member of a population at a single point in time, vital registration systems collect information on individuals as demographic events occur.
