to walk the length of its coil,
telegraphic communication would be effected between all the headquarters
of the army. No orders ever had to be given to establish the telegraph.

The signal service was used on the march. The men composing this corps
were assigned to specified commands. When movements were made, they
would go in advance, or on the flanks, and seize upon high points of
ground giving a commanding view of the country, if cleared, or would
climb tall trees on the highest points if not cleared, and would denote,
by signals, the positions of different parts of our own army, and often
the movements of the enemy. They would also take off the signals of the
enemy and transmit them. It would sometimes take too long a time to
make translations of intercepted dispatches for us to receive any
benefit from them. But sometimes they gave useful information.

On the afternoon of the 7th I received news from Washington announcing
that Sherman had probably attacked Johnston that day, and that Butler
had reached City Point safely and taken it by surprise on the 5th. I
had given orders for a movement by the left flank, fearing that Lee
might move rapidly to Richmond to crush Butler before I could get there.

My order for this movement was as follows:

HEADQUARTERS ARMIES OF THE U. S., May 7, 1864, 6.30 A.M.

MAJOR-GENERAL MEADE, Commanding A. P.

Make all preparations during the day for a night march to take position
at Spottsylvania C. H. with one army corps, at Todd's Tavern with one,
and another near the intersection of the Piney Branch and Spottsylvania
road with the road from Alsop's to Old Court House. If this move is
made the trains should be thrown forward early in the morning to the Ny
River.

I think it would be advisable in making the change to leave Hancock
where he is until Warren passes him. He could then follow and become
the right of the new line. Burnside will move to Piney Branch Church.
Sedgwick can move along the pike to Chancellorsville and on to his
destination. Burnside will move on the plank road to the intersection
of it with the Orange and Fredericksburg plank road, then follow
Sedgwick to his place of destination.

All vehicles should be got out of hearing of the enemy before the troops
move, and then move off quietly.

It is more than probable that the enemy concentrate for a heavy attack
on Hancock this afternoon. In case they do we must be prepared to
resist them, and fol
