Beauregard had the best ground for his fears. As the strongest numerically and occupying the inner and therefore the shorter lines of the opposing works, and with a strong fleet of gunboats in the river to fall back to the shelter of in case of disaster, the initiative belonged to us. And indeed a force did move out from our line the 9th of June to attack Petersburgh. General Gillmore with 3,000 infantry, accompanied by General Kautz with 1,500 cavalry, crossed the Appomattox on the ponton bridge at Port Walthall in the early morning. Gillmore moved out on the City Point Road, and Kautz moved to the left four or five miles to reach the Jerusalem Plank Road. Gillmore finding the works before him strong ones, and apparently well manned, did not attempt to assault them, returning to Bermuda Hundred that afternoon. Kautz attacked on the plank road with indifferent success at first, but finally flanked the enemy's line, forcing them out of their ranks, then marched on the city, but reinforcements coming to the enemy and Gillmore not supporting him, Kautz was forced to withdraw. But more formidable opposing forces than were those of Butler and Beauregard, forces commanded perhaps by greater chieftains than they, too, were now moving to the position of which Petersburgh was the central figure, now to become the most important position of the war.

Before the battle of Cold Harbor was fought by the Army of the Potomac and the portion of the Army of the James sent to Grant under General Smith, Grant had about given up all hope of breaking through Lee's defence on the north side of the James, and had planned, if this last effort failed, to move across the James to a position before Petersburgh, hoping to be able to move so unexpectedly to Lee as to effect the capture of Petersburgh, the turning of Beauregard's Bermuda Hundred line, and to cut off Confederate communication with North Carolina before Lee should realize Grant's object sufficiently to checkmate it by throwing the Army of Northern Virginia across the James and into the Confederate intrenchments at Bermuda Hundred and Petersburgh in time to save them. The part of the Army of the James under General Smith marched to White House, reembarked and sailed for Bermuda Hundred, arriving in the afternoon of June 14th. Smith's force crossed the Appomattox by the ponton bridge at Broadway Landing, two miles from Port Walthall and eight from Petersburgh. Assaulting the works they found in their front, they succeeded in carrying a long line of them. Divisions of the Army of the Potomac began to reach Smith's position that afternoon, crossing the James on a ponton bridge laid down from Wilcox Landing on the north side and Windmill Point on the south, just below City Point, but owing to the exhaustion of troops, missent orders, and various other causes, the success of the forenoon was not followed up, and the 16th and 17th were spent by our forces there in making assaults on the strong and, though mainly defended by artillery, still well defended rebel works. The results were varying during these two days, but without our gaining a position of sufficient strength to enable our columns to overcome the defence of the 18th, when Beauregard's small, almost exhausted and somewhat provisional army was heavily reenforced by Lee's veteran troops.

During this time we were holding the lines of Bermuda Hundred, in hourly expectation on the 16th and 17th of the Army of Northern Virginia assaulting us, it having to pass so near us in moving down the pike and the Richmond and Petersburgh to Beauregard's assistance, that it might easily hurl an assaulting column on our lines and breaking through the inadequate force with which we held them, assail Grant on the flank.

While Beauregard, thoroughly alive to Grant's real purposes through the stories of scouts and spies, and the sifted admissions of the prisoners he captured on the 15th, was showering telegrams on Lee and sending his aides with personal messages to Richmond, Lee was still on the north side of the James throwing out reconnoissances in every direction in search of Grant's real course. This delay of Lee forced Beauregard to hold his lines with a very small force against a constantly augmenting one. But these lines were formidable ones. A born engineer as well as an educated one, Beauregard had from sheer restlessness already entrenched every practicable position around Petersburgh, planting enfilading batteries on all commanding points, and generally had already planned and arranged the lines of works that, with little modification of position, held Petersburgh so long against our armies.

Knowing that the force in his front was steadily growing as divisions of the Army of the Potomac came on the ground and went into position, and that the 16th would be a day of trial to him, Beauregard the night of the 15th determined to abandon the Bermuda Hundred line, trusting to the coming of Lee's troops to regain them.

That night he withdrew the force that held the Bermuda Hundred lines, leaving only a mask of pickets, virtually abandoning his whole line from the Howlett House to the Appomattox. He says he had the guns and caissons of the Howlett House Battery removed and buried, the ground above them rearranged with sticks and leaves as not to arouse any suspicion, and that this prize remained safely hidden until the Confederates had regained their line.

The night of the 15th Lieutenant-Colonel Greely of the 10th Connecticut, which regiment was on picket at the Warebottom Church position, hearing movements on the rebel line, crept out and made up his mind from what he heard and saw that the rebels were moving away. Reporting his belief and his reasons for it to General Terry, that officer ordered a movement in the early morning of the 16th that resulted in the capture of the whole rebel line with their pickets and such troops as they had left there.

A force of one hundred day's men from Ohio had reported to General Butler, good material enough, but in the nature of things quite undisciplined, mere raw recruits, and without the veteran organization of officers and men that enabled our own new men to do such good work. These new troops were placed in the captured lines, while we held our own outer line just across the slashing dividing the two lines of intrenchments. They now held their position beautifully so long as they were not troubled by the Confederates, but along in the afternoon a commotion was visible among them, then a few came hurrying over the works they were in, then more and more, a confused firing was heard, then the "rebel yell" rose clear and shrill and the whole force of Ohio men came flocking over the works and across the slashing, a strong skirmish line of gray clothed soldiers moving after them—the van of Lee's army. The hundred day's men came tearing towards us at the top of their speed without order or orders so far as could be seen. We opened ranks to let them through, the scared white faced flock of sheep, one of them, I remember, holding up a hand from which the blood was trickling from a scratch probably made by a limb of a fallen tree of the slashing, lamentably crying "I'm wounded," "I'm wounded," while our men roared with laughter. What would have become of them—whether they would have stopped short of Ohio—I do not know, had not the 10th Connecticut, on reserve, deployed with fixed bayonets and fenced the mob back.

But we had no time for enjoyment of this part of the comedy. Closing up as the Ohio men passed through us, we turned so heavy a fire on the advancing lines of the enemy that they stopped, staggered, fell back and finally retired to their recaptured works.

At day-break of June 17th, General Osborn says that the Confederates assaulted the Union line in our front and were repulsed, but when they assaulted in the afternoon they broke through a portion of the line, driving it back.
