What was the Civil War's bloodiest battle?
Answer: Battle of Gettysburg
CivilWar.Org - "The Civil War devastated the Confederate states. The presence of vast armies throughout the countryside meant that livestock, crops, and other staples were consumed very quickly. In an effort to gather fresh supplies and intimidate the United States, Confederate General Robert E. Lee launched a daring invasion of the North in the summer of 1863. He was defeated by Union General George G. Meade in a three-day battle near Gettysburg, Pennsylvania that left nearly 52,000 men killed, wounded, or missing in action. Many historians mark the Battle of Gettysburg as the “turning point” in the Civil War when the South began to lose. After the battle, President Lincoln delivered the Gettysburg Address, which expressed firm commitment to preserving the Union and became one of the most famous speeches in American history."
