By following me to Dinwiddie the enemy’s infantry had completely isolated itself, and hence there was now offered the Union troops a rare opportunity. Lee was outside of his works, just as we desired, and the general-in-chief realized this the moment he received the first report of my situation; General Meade appreciated it too from the information he got from Captain Sheridan, en route to army headquarters with the first tidings, and sent this telegram to General Grant:
“HEADQUARTERS OF THE ARMY OF THE POTOMAC,
“March 31, 1865. 9:45 p.m.
“LIEUTENANT-GENERAL GRANT:
“Would it not be well for Warren to go down with his whole corps and smash up the force in front of Sheridan? Humphreys can hold the line to the Boydton plank-road, and the refusal along with it. Bartlett’s brigade is now on the road from G. Boisseau’s, running north, where it crosses Gravelly Run, he having gone down the White Oak road. Warren could go at once that way, and take the force threatening Sheridan in rear at Dinwiddie, and move on the enemy’s rear with the other two.
“G. G. MEADE, Major-General.”
An hour later General Grant replied in these words:
“HEADQUARTERS ARMIES OF THE UNITED STATES,
“DABNEY’S MILLS, March 311, 1865. 10:15
P. M.
“MAJOR-GENERAL MEADE,
“Commanding Army of the Potomac.
Let Warren move in the way you propose, and urge him not to stop for anything. Let Griffin (Griffin had been ordered by Warren to the Boydton road to protect his rear) go on as he was first directed.
“U. S. GRANT, Lieutenant-General.”
These two despatches were the initiatory steps in sending the Fifth Corps, under Major-General G. K. Warren, to report to me, and when I received word of its coming and also that Genera Mackenzie’s cavalry from the Army of the James was likewise to be added to my command, and that discretionary authority was given me to use all my forces against Pickett, I resolved to destroy him, if it was within the bounds of possibility, before he could rejoin Lee.
