Many a man stood there, and silently wished some of their loved ones could meet and greet them also. The entrance of the boys in blue into Frederick was a perfect ovation. General Lee had retired from the town only two days before. This welcome thrilled their hearts. From every door and window the national flag fluttered, and the stores were decorated with the colors. Banners were strung across the streets, from house to house, while crowds of happy men and women with radiant faces, spoke words of welcome. Good luck seemed to be showered upon them, for General McClellan here captured a copy of the orders of General Lee, which gave him a key to the whole situation. It was of very recent date, and the Confederate commander had mapped out his campaign. The {125}information contained in these explicit instructions to his generals, enabled General McClellan to see plainly how to thwart General Lee. So he proceeded to send two corps through the two Gaps of South Mountain, with the prospect of being able to cut the enemy's forces to pieces. [Illustration: 9133] Dividing his command, General McClellan ordered Franklin to Crampton's Gap, while Reno and Hooker, with Burnside at their head, were sent to Turner's Gap. It was a toilsome task for even those sturdy men to ascend the sides of the Gaps. South Mountain towered a thousand feet above them, while the most accessible points were the two Gaps, each nearly 400 feet high. “We've got to reach the top of those hills somehow,” Ralph said. “But it's one step forward, and three backward. Our men are gaining a little. They show splendid pluck.” Clambering, toiling up the rocky hillsides, the Union forces made their painful way. From behind ledges and trees, the rebel riflemen marked their slow progress, and sent many a man to his death. The company to which Ralph belonged was under Reno, and assaulted the southern crest of Turner's Gap. On the northern crest of the mountain General Hooker, with splendid courage, kept on. {126} [Illustration: 0134] Ralph now realized how desperately men will fight. He even felt that hot hatred which two foes ever feel, when pitted against each other. He saw the Federal army, scratched and bruised from forcing their way through the brush and over rocks, while the Confederate riflemen poured bullets into their midst like {127}rain. Hot, and panting with their efforts, still they never wavered. Gibbon, with his brigade, was trying to force a passage through the turnpike in the Gap, and here also the enemy did terrible execution. The heat was blistering. The fervid rays of the September sun burned into their very blood, and the dust which rose in clouds mixed with the smoke of the powder, and choked and blinded them.
