d so well.

If General Hancock's orders of the 15th had been communicated to him,
that officer, with his usual promptness, would undoubtedly have been
upon the ground around Petersburg as early as four o'clock in the
afternoon of the 15th. The days were long and it would have given him
considerable time before night. I do not think there is any doubt that
Petersburg itself could have been carried without much loss; or, at
least, if protected by inner detached works, that a line could have been
established very much in rear of the one then occupied by the enemy.
This would have given us control of both the Weldon and South Side
railroads. This would also have saved an immense amount of hard
fighting which had to be done from the 15th to the 18th, and would have
given us greatly the advantage in the long siege which ensued.

I now ordered the troops to be put under cover and allowed some of the
rest which they had so long needed. They remained quiet, except that
there was more or less firing every day, until the 22d, when General
Meade ordered an advance towards the Weldon Railroad. We were very
anxious to get to that road, and even round to the South Side Railroad
if possible.

Meade moved Hancock's corps, now commanded by Birney, to the left, with
a view to at least force the enemy to stay within the limits of his own
line. General Wright, with the 6th corps, was ordered by a road farther
south, to march directly for the Weldon road. The enemy passed in
between these two corps and attacked vigorously, and with very serious
results to the National troops, who were then withdrawn from their
advanced position.

The Army of the Potomac was given the investment of Petersburg, while
the Army of the James held Bermuda Hundred and all the ground we
possessed north of the James River. The 9th corps, Burnside's, was
placed upon the right at Petersburg; the 5th, Warren's, next; the 2d,
Birney's, next; then the 6th, Wright's, broken off to the left and
south. Thus began the siege of Petersburg.
