 Well, the 20th Maine is marching now into Gettysburg, and Gouverneur Warren, it's a wonderful statue there today with his spy glasses or field glasses, looks up at this craggy hill called Little Round Top and said, oh my goodness, it's undefended. Whoever will get to the top of Little Round Top will have a great advantage. And so the rush is to get to the top and therefore to defend the far left of the Union line.
