onsisting of citizens and
employees in the city who took up arms in case of emergency. Smith
started as proposed, but his advance encountered a rebel force
intrenched between City Point and their lines outside of Petersburg.
This position he carried, with some loss to the enemy; but there was so
much delay that it was daylight before his troops really got off from
there. While there I informed General Butler that Hancock's corps would
cross the river and move to Petersburg to support Smith in case the
latter was successful, and that I could reinforce there more rapidly
than Lee could reinforce from his position.

I returned down the river to where the troops of the Army of the Potomac
now were, communicated to General Meade, in writing, the directions I
had given to General Butler and directed him (Meade) to cross Hancock's
corps over under cover of night, and push them forward in the morning to
Petersburg; halting them, however, at a designated point until they
could hear from Smith. I also informed General Meade that I had ordered
rations from Bermuda Hundred for Hancock's corps, and desired him to
issue them speedily, and to lose no more time than was absolutely
necessary. The rations did not reach him, however, and Hancock, while
he got all his corps over during the night, remained until half-past ten
in the hope of receiving them. He then moved without them, and on the
road received a note from General W. F. Smith, asking him to come on.
This seems to be the first information that General Hancock had received
of the fact that he was to go to Petersburg, or that anything particular
was expected of him. Otherwise he would have been there by four o'clock
in the afternoon.

Smith arrived in front of the enemy's lines early in the forenoon of the
15th, and spent the day until after seven o'clock in the evening in
reconnoitering what appeared to be empty works. The enemy's line
consisted of redans occupying commanding positions, with rifle-pits
connecting them. To the east side of Petersburg, from the Appomattox
back, there were thirteen of these redans extending a distance of
several miles, probably three. If they had been properly manned they
could have held out against any force that could have attacked them, at
least until reinforcements could have got up from the north of Richmond.

Smith assaulted with the colored troops, and with success. By nine
o'clock at night he was in possession of five of these r
