Lieutenant Charles E. Hazlett of Battery D, Fifth United States Artillery, felt that his six 10 Pounder Parrott rifles should be at the summit of Little Round Top. General Warren thought that it was “no place for efficient artillery fire” since the guns could not depress their tubes enough to defend their immediate front. But Hazlett made the point that “the sound of my guns will be encouraging to our troops and disheartening to the others, and my battery’s no use if this hill is lost.” The men of Battery D fought to move the guns up the rugged slope, with one gun amazingly driven to the top and the rest practically carried into position. This was an incredible feat by itself – the tube and carriage of a 10 pounder Parrott weigh 1,799 pounds. Only the guns would fit on the narrow hilltop – ammunition would be run up the hill from the caissons parked down the slope.
Staying alive on the hilltop was another feat. Before the first gun could fire, a bullet hit its sponge bucket, emptying the water. Warren was grazed by a bullet across his throat before he moved on to bring up more reinforcements. Brigade commander Stephen Weed fell, mortally wounded, and when Hazlett knelt to speak with him he, too, was mortally wounded. To the right of the leftmost Parrott rifle in the photo is the monument honoring Hazlett and Weed and their defence of Little Round Top.
