In many ways, this has become a forgotten war, a little-known piece of history that few people understand. Saunders of the 2nd Engineer Regiment. Tracer rounds lit up the sky overhead as German machine gunners trained a torrent of lead at the American lines. With rain pelting their faces, Saunders and Wilkerson inched their way toward their target: The two had volunteered for a virtual suicide mission: The story of that daring mission is retold in my bestselling book, The Unknowns: On May 12,at the age of 25, Saunders had enlisted in the U.
Both sides of the conflict revered the Indian warriors. Legend suggested that Indians had otherworldly abilities to move silently through the forest, find their way in the dark, travel long distances with limited rest and food, and defeat any enemy in hand-to-hand combat.
While these stereotypes were more myth than reality, Native soldiers frequently distinguished themselves when serving as scouts, messengers, and combat engineers. They also sometimes served an invaluable function by transmitting radio messages in their tribal languages, which were undecipherable to Germans who might intercept the calls.
Pershing, launched an attack against German forces near the town of St. It was the first real test for the United States in World War I, a chance to prove themselves to their European allies, who largely viewed the Americans as bungling novices who knew little about the art of war.
But before that assault could begin, Saunders and Wilkerson had to clear the way. Using heavy, two-handled wire cutters, the duo painstakingly snipped through the nests of wire, one at a time.
For hours, they toiled in the darkness, muscles bulging as they strained at their task while enemy machine gunners and artillery tried to take them down. As dawn began to cast its glow on the gray, trench-covered landscape, Saunders and Wilkerson cut through the last piece of wire.
But their job was far from done.
They were fighting engineers, which meant that as soon as they were finished with their wire cutters, they drew their weapons and headed for the German trenches, becoming some of the first Americans to cross the German lines at St.
Leading a small group of men, Saunders fought his way forward toward the hamlet of Jaulny. As the men pressed deeper behind the lines, machine-gun and sniper fire grew increasingly intense.
Striking ahead on their own, Saunders and Wilkerson doggedly advanced toward the castle, bounding through trenches and foxholes as bullets whizzed by on every side.
They soon encountered a dugout manned by eight Germans, whom the Americans took prisoner. Heedless of their own survival, the two Americans cautiously entered the stone edifice, and they cleared the structure, taking prisoner everyone they found.
Remarkably, the two men rounded up 55 more prisoners in the castle and the town, bringing their total for the single day to The AEF achieved an unequivocal victory at St. Mihiel, placing the Germans off balance and setting up the coming battles in the Meuse-Argonne and Blanc Mont Ridge, where Saunders was once again decorated.
As the war progressed, Saunders participated in several more battles, frequently displaying courage that set him apart from his fellow soldiers.
In my close contacts, during and since the World War with Saunders, I can state that everything he does is a bit better and with more energy than other men of equal physique would do the same thing.
At that memorial, another Native American, Chief Plenty Coups, also honored the Unknown Soldier and all the American Indians who had served in the war by placing his feathered war bonnet and coup stick in the sarcophagus alongside the body. He then addressed the crowd, saying: I am glad to represent all the Indians of the United States in placing on the grave of this noble warrior this coup stick and war bonnet, every eagle feather of which represents a deed of valor by my race.
I hope that the Great Spirit will grant that these noble warriors have not given up their lives in vain and that there will be peace to all men hereafter.
That prayer for peace on earth has yet to be answered, but it remains a fitting dream a century after the end of the first World War. Perhaps in remembering the actions and sacrifices of the men who took part in that conflict, we can move closer to that worthy goal.

A great training tool to novice and experienced shooters alike. Ricochets are immediately seen, and will provide Syracuse Post-Standard. After writing a . Typical tracer rounds are incendiary, i.e., the base of the bullet contains a flammable compound that is ignited when the cartridge is fired.
The intended effect is to make the bullet’s flight path from the muzzle to the target readily visible, enabling the shooter to immediately adjust aim as needed. Paddock bought 1, rounds of thecaliber andcaliber tracer ammunition from a private buyer he met at a Phoenix gun show, a law enforcement official not authorized to comment on the Founded: Sep 18, In the last post, we implemented all of the logic necessary to build a true path tracer.
Problem is, even on the GPU it’s terrifically slow. Writing a GPU-Accelerated Path Tracer in Rust - Part 3. 17 minute the grid size, and the rest are self-explanatory.
I’ll go with a fudge factor of because that seems like a nice, round. Tracer ammunition (tracers) are bullets or cannon caliber projectiles that are built with a small pyrotechnic charge in their base.
Ignited by the burning powder, the pyrotechnic composition burns very brightly, making the projectile trajectory visible to the naked eye during daylight, and very bright during nighttime firing.
