"I wish," says the _petit caporal_ of the Engineer Company, patting his howitzer gently on the back, "that I could get this Putty Blower pointed at the enemy, while you fellows are bridge-building." The inefficient destructives of Maryland had only half spoilt the bridge. Some of the old timbers could be used,--and for new ones, there was the forest. Scott and his party made a good and a quick job of it. Our friends of the Massachusetts Eighth had now come up. They lent a ready hand, as usual. The sun set brilliantly. By twilight there was a practicable bridge. The engine was dispatched back to keep the road open. The two platform cars, freighted with our howitzers, were rigged with the gun-ropes for dragging along the rail. We passed through the files of the Massachusetts men, resting by the way, and eating by the fires of the evening the suppers we had in great part provided them; and so begins our night-march. THE NIGHT-MARCH O GOTTSCHALK! what a poetic _Marche de Nuit_ we then began to play, with our heels and toes, on the railroad track! It was full-moonlight and the night inexpressibly sweet and serene. The air was cool and vivified by the gust and shower of the afternoon. Fresh spring was in every breath. Our fellows had forgotten that this morning they were hot and disgusted. Everyone hugged his rifle as if it were the arm of the Girl of his Heart, and stepped out gayly for the promenade. Tired or foot-sore men, or even lazy ones, could mount upon the two freight-cars we were using for artillery-wagons. There were stout arms enough to tow the whole. The scouts went ahead under First Lieutenant Farnham of the Second Company. We were at school together,--I am afraid to say how many years ago. He is just the same cool, dry, shrewd fellow he was as a boy, and a most efficient officer. It was an original kind of march. I suppose a battery of howitzers never before found itself mounted upon cars, ready to open fire at once and bang away into the offing with shrapnel or into the bushes with canister. Our line extended a half-mile along the track. It was beautiful to stand on the bank above a cutting, and watch the files strike from the shadow of a wood into a broad flame of moonlight, every rifle sparkling up alert as it came forward. A beautiful sight to see the barrels writing themselves upon the dimness, each a silver flash. By and by, "Halt!" came, repeated along from the front, company after company. "Halt! a rail gone." It was found without difficulty. The imbeciles who took it up probably supposed we would not wish to wet our feet by searching for it in the dewy grass of the next field. With incredible doltishness they had also left the chairs and spikes beside the track. Bonnell took hold, and in a few minutes had the rail in place and firm enough to pass the engine. Remember, we were not only hurrying on to succor Washington, but opening the only convenient and practicable route between it and the loyal States.
