e would be
standing apparently on firm ground, when all at once one foot would
sink, and as he commenced scrambling to catch himself all his feet would
sink and he would have to be drawn by hand out of the quicksands so
common in that part of Virginia and other southern States. It became
necessary therefore to build corduroy roads every foot of the way as we
advanced, to move our artillery upon. The army had become so accustomed
to this kind of work, and were so well prepared for it, that it was done
very rapidly. The next day, March 30th, we had made sufficient progress
to the south-west to warrant me in starting Sheridan with his cavalry
over by Dinwiddie with instructions to then come up by the road leading
north-west to Five Forks, thus menacing the right of Lee's line.

This movement was made for the purpose of extending our lines to the
west as far as practicable towards the enemy's extreme right, or Five
Forks. The column moving detached from the army still in the trenches
was, excluding the cavalry, very small. The forces in the trenches were
themselves extending to the left flank. Warren was on the extreme left
when the extension began, but Humphreys was marched around later and
thrown into line between him and Five Forks.

My hope was that Sheridan would be able to carry Five Forks, get on the
enemy's right flank and rear, and force them to weaken their centre to
protect their right so that an assault in the centre might be
successfully made. General Wright's corps had been designated to make
this assault, which I intended to order as soon as information reached
me of Sheridan's success. He was to move under cover as close to the
enemy as he could get.

It is natural to suppose that Lee would understand my design to be to
get up to the South Side and ultimately to the Danville Railroad, as
soon as he had heard of the movement commenced on the 29th. These roads
were so important to his very existence while he remained in Richmond
and Petersburg, and of such vital importance to him even in case of
retreat, that naturally he would make most strenuous efforts to defend
them. He did on the 30th send Pickett with five brigades to reinforce
Five Forks. He also sent around to the right of his army some two or
three other divisions, besides directing that other troops be held in
readiness on the north side of the James River to come over on call. He
came over himself to superintend in person the defence of
