| caption = The intensity of artillery fire at Antietam led Colonel Stephen D. Lee, commander of the Confederate cannons shown here, to describe the battle as "Artillery Hell." This painting depicts the earliest part of the battle. The artist's perspective is close to the present-day location of the Visitor Center. Notice the Dunker Church on the left side of the painting. On the right is approximately 5,000 men from Sedgewick's Division of Sumner's II Corp advancing toward the West Woods at about 9:00 am.About the artist. Captain James Hope, a professional artist, was 43 years old and a member of the 2nd Vermont Infantry. Hope had taken part in a dozen engagements prior to Antietam, but disabled by illness, was assigned to sideline duties as a scout and mapmaker. He recorded in his sketchbook the battle scenes before his eyes, and then after the battle converted his sketches into a series of five large paintings.Courtesy of http://www.civilwarhome.com/antietamshsp.htm and Antietam National Battlefield.
