This statue of Gen. G. K. Warren is perched on Little Round Top. Warren is credited with realizing that Confederates would make a push for the hill and for calling for reinforcements to push them back, which they did. He was lauded for his role in that battle and was often called the “Hero of Little Round Top,” but his military career was eventually ruined.  (Catharine Hamm / Los Angeles Times)

The Seminary Ridge Museum is to open July 1 in Gettysburg. One of its three areas of emphasis is care given to soldiers in the aftermath of a battle that left 20,000 wounded.

Cycloramas -- paintings in the round -- were the cinema of their day. An 1883-84 painting of the Gettysburg Battle by French artist Paul Philippoteaux has been restored and remounted at Gettysburg in the National Park Service Museum and Visitor Center. Optical illusions-dioramas and a “disappearing sky” help bring the conflict to life.  (Catharine Hamm / Los Angeles Times)

Not all who fought were fresh-faced young soldiers. This statue is dedicated to John Burns, a vet of the War of 1812. By the time of the battle at Gettysburg, Pa., he was nearing 70 but on the morning of the battle, he grabbed his musket and fought for the Union. He was wounded three times. He recovered and became a minor celebrity.  (Catharine Hamm / Los Angeles Times)
