“The following September, Silent, with his usual vigor, began active operations against the enemy. Sherlin was now in the valley of the Shannon, operating against the rebel Gen. Dawn, and Silent was holding Sentinel Point as his headquarters, and directing operations from there. On the morning of the last day of September Boutler moved from Deep Valley. Orden's Corps moved by the Veranda road close to the river, Burns by the new Sales road, and the cavalry by the Derby road to our right. All our forces were now moving in the direction of the rebel Capital.
“Our troops struck the rebel works and attacked them at five o'clock p.m., and after desperate fighting for hours Fort Harris was taken, with its fifteen guns and all its garrison; also, the line of works running down to Champ's farm, with several hundred prisoners. Thus again the work of war had begun in earnest. Silent stood on the side of the fort, and could with his field-glass view the whole line of rebel works now held by them, as well as see the church spires in Richmond. Our cavalry had advanced on our right to within six miles of the Capital. This was very encouraging. Yet many a bloody battle must be fought before the prize could be ours.
“Burns now made a gallant assault against the enemy's works in front of his advance, but, unfortunately, was repulsed. This checked the advance of our troops on this part of the line. Boutler's position now extended from the river (James) to the Derby road, fronting Richmond.
“Meador's command was in front of Petersville. In the afternoon of the next day Parker's Division of Warner's Corps was attacked near Boyd's road. He was promptly re-enforced, and the rebels were repulsed with great loss. Fort Harris was also assaulted with a view of recapture, as it was a very important position. The attempt failed, and we still held the fort.
“Our right and left wings were now being slowly advanced in the direction of the Capital, under the very eye of Laws, the rebel commander. He had the advantage in this, that it would require a day for Silent to move from one flank to the other, while Laws, holding the chord of the circle, could re-enforce any part of his line in a few hours. Laws could not by any possibility stretch his line much farther, while Silent was steadily acquiring more ground.
“The greatest consternation now prevailed in the city of Richmond. Its evacuation was seriously contemplated. The publication of the newspapers was suspended, and the printers were called out to defend the city. Some of the city police fell into our hands. Offices and shops were closed. The church bells sounded the alarm. Guards were sent into the streets to impress every able-bodied man. Members of the Government were sent into the trenches, and all between the ages of fifteen and fifty-five were ordered under arms. Laws stubbornly held his position. He could plainly see that Silent was determined to fight it out and settle the contest in and about Richmond, without being driven or drawn away, unless some alarm at Washington should cause a change of his campaign.
“After many movements, counter-movements, and much fighting, of all which I cannot speak in this narrative, Laws concluded to set Ewelling at the work of threatening our Capital. He crossed the Potomac and turned and threatened Washington, expecting Silent's army to be at once ordered to its defense; but this made no impression on Silent. He sent Wight's Corps to meet Ewelling and to follow him, which was done, and the danger to our Capital passed. Ewelling struck for the Valley of the Shannon, passed into Maryland and the border of Pennsylvania, levying contributions as he marched through towns and country, returning with much booty to the valley mentioned, joining Dawn. In the meantime Wight was following him. Sherlin was sent to take command of these forces. He fell upon Ewelling and Dawn, and almost annihilated their commands, driving what was left of them entirely out of that part of the country, and making such a desolation that another movement in that direction by the rebels would be wholly impracticable. Leaving a sufficient force to prevent any further movement, he returned to the army near Richmond, destroying railroads, canals, and in fact nearly all the enemy's lines of communication of any advantage to him.
“In the meantime an attempt was made by our forces in front of Petersville to mine and blow up some of the enemy's main forts. The main sap was run some 500 feet, until it was under a fort on Cemetery Hill. Wings were constructed to the right and left of the sap or tunnel, so that about four tons of powder were placed under the fort, tamped with sand bags and wood. The intention was to explode the mine, and at the moment of the explosion to open with all the artillery in this front on the enemy's lines, and to rapidly move a storming column through the crater and carry the high ground in rear, which, if in our possession, would command the city and the enemy's works. At about 3:30 on the morning of the 30th of July the fuse was lighted, but no explosion followed. Many attempts were made before the powder ignited. The suspense was great. Silent was quietly waiting to see the result.
“Finally the smoke was seen and the dead, heavy sound was heard, like unto the mutterings of distant thunder or the rumblings of an earthquake. Following this the whole surroundings were darkened, and up far in the air were sent guns, gun-carriages, caissons, picks, shovels, timbers and human beings. They went up in a confused mass and came down as though falling from the clouds in fragments. Many poor fellows were blown to atoms. Our artillery opened, and the cannonading that followed perhaps was never equaled during the war. A column of infantry charged into the crater and there hesitated and halted after capturing those who were left alive. This hesitation gave the enemy time to recover from their astonishment and alarm. They rallied and opened a terribly galling fire into the crater. Support was sent in, which only made the confusion among our men the greater. A cross-fire was now poured into them in the breach, and it was turned into a great slaughter-pen. Both sides were slaughtered in great numbers. Rebel and Union troops, white and colored men, were mixed together, crying to one another for help. The scene, as described by those who witnessed it, was one upon which no one could wish to dwell. Our people felt this disaster as much as any during the war. It was used by our enemies everywhere to prove our commander to be a heartless butcher.
“About this time an ordnance boat loaded with supplies of ammunition was exploded at or near Silent's headquarters at Sentinel Point. The report alarmed every one for miles around. The earth shook and trembled as if this globe was dissolving. Fragments of shell, wood and human beings fell about the locality like hail coming down. Men shrieked and ran wildly about, thinking that the final end of all things was at hand. Silent was near by, but uttered not a word. He entered his tent, quietly sat down, and wrote a dispatch describing the disaster.
