On the 11th of April  at five o'clock, an event at once amusing and thrilling occurred at our quarters. The commander-in-chief had appointed his personal and confidential friend, General Fitz John Porter, to conduct the siege of Yorktown. Porter was a polite, soldierly gentleman, and a native of New Hampshire, who had been in the regular army since early manhood. He fought gallantly in the Mexican war, being thrice promoted and once seriously wounded, and he was now forty years of age, handsome, enthusiastic, ambitious, and popular. He made frequent ascension with Lowe, and learned to go aloft alone. One day he ascended thrice, and finally seemed as cozy at home in the firmament as upon the solid earth. It is needless to say that he grew careless, and on this particular morning leaped into the car. and demanded the cables to be let out with all speed. I saw with some surprise that the flurried assistants were sending up the great straining canvas with a single rope attached. The enormous bag was only partially inflated, and the loose folds opened and shut with a crack like that of a musket. Noisily, fitfully, the yellow mass rose into the sky, the basket rocking like a feather in the zephyr; and just as I turned aside to speak to a comrade, a sound came from overhead, like the explosion of a shell, and something striking me across the face laid me flat upon the ground.
Half blind and stunned, I staggered to my feet, but the air seemed full of cries and curses. Opening my eyes ruefully, I saw all faces turned upwards, and when I looked above, the balloon was adrift.
The treacherous cable, rotted with vitriol, had snapped in twain; one fragment had been the cause of my downfall, and the other trailed, like a great entrails from the receding car, where Fitz John Porter was bounding upward upon a Pegasus that he could neither check nor direct.
The whole army was agitated by the unwonted occurrence. From battery No. 1, on the brink of the York, to the mouth of Warwick river, every soldier and officer was absorbed. Far within the Confederate lines the confusion extended. We heard the enemy's alarm-guns, and directly the signal flags were waving up and down our front.
The General appeared directly over the edge of the car. He was tossing his hands frightfully, and shouting something that we could not comprehend.
"O-pen-the-valve! " called Lowe, in his shrill tones; "climb-to-the-netting-and-reach-the-valve-rope."
"The valve!-the valve!" repeated a multitude of tongues, and all gazed with thrilling interest at the retreating hulk that still kept straight upward, swerving neither to the east nor the west.
It was a weird spectacle,-that frail, fading oval, gliding against the sky, floating in the serene azure, the little vessel swinging silently beneath, and a hundred thousand martial men watching the loss of their brother in arms, but powerless to relieve or recover him. Had Fitz John Porter been drifting down the rapids of Niagara, he could not have been so far from human assistance. But we saw him directly, no bigger than a child's toy, clambering up the netting and reaching for the cord.
"He can't do it," muttered a man beside me; "the wind blows the envelope to and fro, and only a spry, cool-headed fellow can catch it."
We saw the General descend, and appearing again over the edge of the basket, he seemed to be motioning to the breathless hordes below, the story of his failure. Then he dropped out of sight, and when we next saw him, he ,as reconnoitering the Confederate works through a long black spy-glass. A gloat laugh went up and down the lines as this cool procedure was observed, aid then a cheer of applause ran from group to group. For a moment it was doubtful that the balloon would float in either direction; it seemed to falter, like an irresolute being, and moved reluctantly southeastward, towards Fortress Monroe. A huzza, half uttered, quivered on every lip. All eyes glistened, and some were dim with tears of joy. But the wayward canvas now turned due westward, and was blown rapidly toward the Confederate works. Its course was fitfully direct, and the wind seemed to veer often, as if contrary currents, conscious of the opportunity, were struggling for the possession of the daring navigator. The south wind held mastery for awhile, and the balloon passed the Federal front amid a howl of despair from the soldiery. It kept right on, over sharpshooters, rifle-pits, and outworks, and finally passed, as if to deliver up its freight, directly over the heights of Yorktown.
The cool courage, either of heroism or despair, had seized upon Fitz John Porter. He turned his black glass upon the ramparts and masked cannon below, upon the remote camps, upon the beleaguered town, upon the guns of Gloucester Point, and upon distant Norfolk. Had he been reconnoitering from a secure perch at the tip of the moon, he could not have been more vigilant, and the Confederates probably thought this some Yankee device to peer, into their sanctuary in despite of ball or shell. None of their great guns could be brought to bear upon the balloon; but there were some discharges of musketry that appeared to have no effect, and finally even these demonstrations ceased. Both armies in solemn silence were gazing aloft, while the imperturbable mariner continued to spy out the land.
The sun was now rising behind us, and roseate rays struggled up to the zenith, like the arcs made by showery bombs. They threw a hazy atmosphere upon the balloon, and the light shone through the network like the sun through the ribs of the skeleton ship in the Ancient Mariner. Then, as l looked agape, the air-craft "plunged, and tacked, and veered," and drifted rapidly toward the Federal lines again.
The allelujah that now went up shook the spheres, and when he had regained our camp limits, the General was seen clambering up again to clutch the valve-rope. This time he was successful, and the balloon fell like a stone, so that all hearts once more leaped up, and the cheers were hushed. Cavalry rode pell-mell from several directions, to reach the place of descent, and the General's personal staff galloped past me like the wind, to be the first at his debarkation. I followed the throng of soldiery with due haste, and came up to the horsemen in a few minutes. The balloon had struck a canvas tent with great violence, felling it as by a bolt, and the General, unharmed, had disentangled himself from innumerable folds of oiled canvas, and was now the cynosure of an immense group of people. While the officers shook his hands, the rabble bawled their satisfaction in hurrahs, and a band of music marching up directly, the throng on foot and horse gave him a vociferous escort to his quarters.
