"My leave of absence is short. I shall not have time to make many visits; but it will give me great pleasure to call upon those who have _always_ been my friends," said Paul, with a look so searching that it brought the blood into her faded cheeks. Hearty the welcome from Azalia and Daphne, and from those who had been his scholars, who listened with eager interest to the words which fell from his lips. Golden the days and blissful those few hours spent with his mother, sitting by her side in the old kitchen; with Daphne and Azalia, singing the old songs; with Azalia alone, stealing down the shaded walk in the calm moonlight, talking of the changeful past, and looking into the dreamy future, the whippoorwills and plovers piping to them from the cloverfields, the crickets chirping them a cheerful welcome, and the river saluting them with its ceaseless serenade! CHAPTER XVII. CHICKAMAUGA. Quick the changes. Paul was once more with the army, amid the mountains of Tennessee, marching upon Chattanooga with General Rosecrans, tramping over Lookout Mountain, and along the Chickamauga. Then came a day of disaster in September. A great battle began on Saturday morning, lasted through Sunday, and closed on Monday. Paul rode courageously where duty called him, through the dark woods, along the winding river, where the bullets sang, where the shells burst, where hundreds of brave men fell. Terrible the contest. It was like a thunder-storm among the mountains,--like the growling of the angry surf upon the shore of the ocean. How trying, after hours of hard fighting, to see the lines waver and behold the Rebels move victoriously over the field! with disaster setting in, and to know that all that is worth living for is trembling in the scale! There are such moments in battle. General Rosecrans's army was outnumbered. Paul saw the Rebels driving in the centre and turning the left flank to cut off all retreat to Chattanooga. The moment for great, heroic action had come. He felt the blood leap through his veins as it never had leaped before. The Rebel line was advancing up the hill. The Union batteries were making ready to leave. "Stay where you are!" he shouted. "Give them canister! Double shot the guns! Quick! One minute now is worth a thousand hours."
