Civil war experts and historians have long asked themselves: Why did Confederate Gen. Robert E. Lee order the doomed attack on Little Round Top during the Battle of Gettysburg?

Geographer and college professor Anne Knowles, from Middlebury College in Vermont, believes she has the answer. Using advanced mapping technology, she's recreated the battlefield's geography exactly as Lee saw it.

Her conclusion: Lee simply couldn't see many of the Union soldiers amid the hills and valleys. As a result, the Confederate general greatly underestimated his enemy's troop strength.

Knowles oversaw the development of the digital map for the Smithsonian Institution to mark Gettysburg's 150th anniversary next week.
