others. Some troopers in the brigade commanded by Brig. Gen. William Gamble had Spencer repeating rifles. The breech-loading design of the carbines and rifles meant that Union troops did not have to stand to reload and could do so safely behind cover. This was a great advantage over the Confederates, who still had to stand to reload, thus providing an easier target. But this was so far a relatively bloodless affair. By 10:20 a.m., the Confederates had reached Herr Ridge and had pushed the Federal cavalrymen east to McPherson Ridge, when the vanguard of the I Corps finally arrived, the division of Maj. Gen. James S. Wadsworth. The troops were led personally by Gen. Reynolds, who conferred briefly with Buford and hurried back to bring more men forward. Davis versus Cutler The morning infantry fighting occurred on either side of the Chambersburg Pike, mostly on McPherson Ridge. To the north, an unfinished railroad bed opened three shallow cuts in the ridges. To the south, the dominant features were Willoughby Run and Herbst Woods (sometimes called McPherson Woods, but they were the property of John Herbst). Brig. Gen. Lysander Cutler's Union brigade opposed Davis's brigade; three of Cutler's regiments were north of the Pike, two to the south. To the left of Cutler, Brig. Gen. Solomon Meredith's Iron Brigade opposed Archer. General Reynolds directed both brigades into position and placed guns from the Maine battery of Capt. James A. Hall where Calef's had stood earlier. While the general rode his horse along the east end of Herbst Woods, shouting "Forward men! Forward for God's sake, and drive those fellows out of the woods," he fell from his horse, killed instantly by a bullet striking him behind the ear. (Some historians believe Reynolds was felled by a sharpshooter, but it is more likely that he was killed by random shot in a volley of rifle fire directed at the 2nd Wisconsin.) Maj. Gen. Abner Doubleday assumed command of the I Corps. On the right of the Union line, three regiments of Cutler's brigade were fired on by Davis's brigade before they could get into position on the ridge. Davis's line overlapped the right of Cutler's, making the Union position untenable, and Wadsworth ordered Cutler's regiments back to Seminary Ridge. The commander of the 147th New York, Lt. Col. Francis C. Miller, was shot before he could inform his troops of the withdrawal,
