Title: Antietam Creek
Content:  The term "Antietam" is thought to derive from an Algonquian phrase meaning "swift-flowing stream". Historical and variant names include Andiedom, Andirton Creek, Ant-eat-em Creek, Anticturn Creek, Antieatum Creek, Crooked Brook, Odieta Creek and Ondieta Creek. The creek is noted for numerous well-preserved stone arch bridges dating to the 19th century that still traverse the creek, the most famous of which is the 125 ft Burnside's Bridge in the Antietam National Battlefield. The creek was a major topographic feature during the Battle of Antietam or Sharpsburg, fought on September 17, 1862, near the creek's mouth. Burnside's Bridge became a major focus of combat as Union forces under General Ambrose Burnside repeatedly tried to capture the bridge from Confederate forces guarding the crossing from a high bluff overlooking the creek. The day of the battle is known as "the day Antietam Creek ran red" due to the blood of thousands of Union casualties mixing with the creek waters. Both sides lost about a fourth of their number but, despite General McClellan's refusal to press on his attacks, it served as a tactical Union victory, as Lee was forced to withdraw from Maryland.
