ted this as a semi-retreat of the Army
of the Potomac to Fredericksburg, and so informed his government.
Accordingly he ordered Longstreet's corps--now commanded by Anderson--to
move in the morning (the 8th) to Spottsylvania. But the woods being
still on fire, Anderson could not go into bivouac, and marched directly
on to his destination that night. By this accident Lee got possession
of Spottsylvania. It is impossible to say now what would have been the
result if Lee's orders had been obeyed as given; but it is certain that
we would have been in Spottsylvania, and between him and his capital.
My belief is that there would have been a race between the two armies to
see which could reach Richmond first, and the Army of the Potomac would
have had the shorter line. Thus, twice since crossing the Rapidan we
came near closing the campaign, so far as battles were concerned, from
the Rapidan to the James River or Richmond. The first failure was
caused by our not following up the success gained over Hill's corps on
the morning of the 6th, as before described: the second, when fires
caused by that battle drove Anderson to make a march during the night of
the 7th-8th which he was ordered to commence on the morning of the 8th.
But accident often decides the fate of battle.

Sheridan's cavalry had had considerable fighting during the afternoon of
the 7th, lasting at Todd's Tavern until after night, with the field his
at the close. He issued the necessary orders for seizing Spottsylvania
and holding the bridge over the Po River, which Lee's troops would have
to cross to get to Spottsylvania. But Meade changed Sheridan's orders
to Merritt--who was holding the bridge--on his arrival at Todd's Tavern,
and thereby left the road free for Anderson when he came up. Wilson,
who was ordered to seize the town, did so, with his division of cavalry;
but he could not hold it against the Confederate corps which had not
been detained at the crossing of the Po, as it would have been but for
the unfortunate change in Merritt's orders. Had he been permitted to
execute the orders Sheridan gave him, he would have been guarding with
two brigades of cavalry the bridge over the Po River which Anderson had
to cross, and must have detained him long enough to enable Warren to
reinforce Wilson and hold the town.

Anderson soon intrenched himself--if indeed the intrenchments were not
already made--immediately across Warren's front. Warren was not awa
