2. Battery D Fifth U.S. Artillery Position
Two 3-inch Parrott Rifles and two 2.9-inch Parrott Rifles represent the position held by Hazlett's Battery. The two calibers were generally called "10-pounder" based on the weight of their shot. In 1863, the Federal army decided to standardize the 3-inch caliber, and the new type replaced the 2.9-inch guns in time.

3. Gunner's View from the Parrotts
Looking down the barrel of a 3-inch Parrott on top of Little Round Top. Notice how rapidly the hill slopes off into the valley below. Civil War artillery had limitations on elevation which prevented extreme angles. The guns on Little Round Top could not depress to fire upon targets in the valley directly below the hill. But their fire was quite effective against targets at the Devil's Den and other points on Houck's Ridge extending to the north.

Seen from just forward of the battery. The Devil's Den is to the far left. Houck's Ridge extends to the north (right). The valley between the ridge and Little Round Top became known as the Valley of Death.
