the
James were withdrawn, and Hancock and Gregg returned to the front at
Petersburg. On the 25th, the 2d corps and Gregg's division of cavalry,
while at Reams's Station destroying the railroad, were attacked, and
after desperate fighting, a part of our line gave way, and five pieces
of artillery fell into the hands of the enemy.

By the 12th of September, a branch railroad was completed from the City
Point and Petersburg Railroad to the Weldon Railroad, enabling us to
supply, without difficulty, in all weather, the army in front of
Petersburg.

The extension of our lines across the Weldon Railroad compelled the
enemy to so extend his, that it seemed he could have but few troops
north of the James for the defence of Richmond. On the night of the
28th, the 10th corps, Major-General Birney, and the 18th corps,
Major-General Ord commanding, of General Butler's army, were crossed to
the north side of the James, and advanced on the morning of the 29th,
carrying the very strong fortifications and intrenchments below
Chaffin's Farm, known as Fort Harrison, capturing fifteen pieces of
artillery, and the New Market Road and intrenchments. This success was
followed up by a gallant assault upon Fort Gilmer, immediately in front
of the Chaffin Farm fortifications, in which we were repulsed with heavy
loss. Kautz's cavalry was pushed forward on the road to the right of
this, supported by infantry, and reached the enemy's inner line, but was
unable to get further. The position captured from the enemy was so
threatening to Richmond, that I determined to hold it. The enemy made
several desperate attempts to dislodge us, all of which were
unsuccessful, and for which he paid dearly. On the morning of the 30th,
General Meade sent out a reconnoissance with a view to attacking the
enemy's line, if it was found sufficiently weakened by withdrawal of
troops to the north side. In this reconnoissance we captured and held
the enemy's works near Poplar Spring Church. In the afternoon, troops
moving to get to the left of the point gained were attacked by the enemy
in heavy force, and compelled to fall back until supported by the forces
holding the captured works. Our cavalry under Gregg was also attacked,
but repulsed the enemy with great loss.

On the 7th of October, the enemy attacked Kautz's cavalry north of the
James, and drove it back with heavy loss in killed, wounded, and
prisoners, and the loss of all the artillery eight or nin
