He had observed all of Stuart's movements, and it was he who gave Custer the first important information as to what the enemy was doing; which information was transmitted to Gregg, and probably had a determining influence in keeping Custer on the field.
Weber was a born soldier, fitted by nature and acquirements for much higher rank than any he held. Although but 23 years of age, he had seen much service. A private in the Third Michigan infantry in 1861, he was next battalion adjutant of the Second Michigan cavalry, served on the staff of General Elliott, in the southwest, and came home with Alger in 1862, to take a troop in the Sixth Michigan cavalry. The valuable service rendered by him at Gettysburg was fitly recognized by Custer in his official report. He was killed ten days later at Falling Waters, while leading his squadron in a charge which was described by Kilpatrick as "the most gallant ever made." Anticipating a spirited fight, he was eager to have a part in it. "Bob," he said to me a few days before, while marching through Maryland, "I want a chance to make one saber charge." He thought the time had come. His eye flashed and his face flushed as he watched the progress of the fight, fretting and chafing to be held in reserve when the bugle was summoning others to the charge.
The Fifth Michigan, holding the most advanced position, suffered greatly, Hampton having reinforced the confederate line. Among those killed at this stage of the battle was Major Noah H. Ferry, of the Fifth. Repeating rifles are not only effective but wasteful weapons as well, and Colonel Alger, finding that his ammunition had given out, felt compelled to retire his regiment and seek his horses. Seeing this, the enemy sprang forward with a yell. The union line was seen to yield. The puffs of smoke from the muzzles of their guns had almost ceased. It was plain the Michigan men were out of ammunition and unable to maintain the contest longer. On from field to field, the line of gray followed in exultant pursuit. Breathed and McGregor opened with redoubled violence. Shells dropped and exploded among the skirmishers, while thicker and faster they fell around the position of the reserves. Pennington replied with astonishing effect, for every shot hit the mark, and the opposing artillerists were unable to silence a single union gun. But still they came, until it seemed that nothing could stop their victorious career. "Men, be ready," said Weber. "We will have to charge that line." But the course of the pursuit took it toward the right, in the direction of Randol's battery where Chester was serving out canister with the same liberal hand displayed by Pennington's lieutenants, Clark, Woodruff and Hamilton.
