Hanover Town is about twenty miles from Richmond. There are two roads leading there; the most direct and shortest one crossing the Chickahominy at Meadow Bridge, near the Virginia Central Railroad, the second going by New and Old Cold Harbor. A few miles out from Hanover Town there is a third road by way of Mechanicsville to Richmond. New Cold Harbor was important to us because while there we both covered the roads back to White House (where our supplies came from), and the roads south-east over which we would have to pass to get to the James River below the Richmond defences.
On the morning of the 28th the army made an early start, and by noon all had crossed except Burnside's corps. This was left on the north side temporarily to guard the large wagon train. A line was at once formed extending south from the river, Wright's corps on the right, Hancock's in the centre, and Warren's on the left, ready to meet the enemy if he should come.
At the same time Sheridan was directed to reconnoitre towards Mechanicsville to find Lee's position. At Hawes' Shop, just where the middle road leaves the direct road to Richmond, he encountered the Confederate cavalry dismounted and partially intrenched. Gregg attacked with his division, but was unable to move the enemy. In the evening Custer came up with a brigade. The attack was now renewed, the cavalry dismounting and charging as infantry. This time the assault was successful, both sides losing a considerable number of men. But our troops had to bury the dead, and found that more Confederate than Union soldiers had been killed. The position was easily held, because our infantry was near.
On the 29th a reconnoissance was made in force, to find the position of Lee. Wright's corps pushed to Hanover Court House. Hancock's corps pushed toward Totopotomoy Creek; Warren's corps to the left on the Shady Grove Church Road, while Burnside was held in reserve. Our advance was pushed forward three miles on the left with but little fighting. There was now an appearance of a movement past our left flank, and Sheridan was sent to meet it.
On the 30th Hancock moved to the Totopotomoy, where he found the enemy strongly fortified. Wright was moved to the right of Hancock's corps, and Burnside was brought forward and crossed, taking position to the left of Hancock. Warren moved up near Huntley Corners on the Shady Grove Church Road. There was some skirmishing along the centre, and in the evening Early attacked Warren with some vigor, driving him back at first, and threatening to turn our left flank. As the best means of reinforcing the left, Hancock was ordered to attack in his front. He carried and held the rifle-pits. While this was going on Warren got his men up, repulsed Early, and drove him more than a mile.
On this day I wrote to Halleck ordering all the pontoons in Washington to be sent to City Point.
In the evening news was received of the arrival of Smith with his corps at White House. I notified Meade, in writing, as follows:
