I was anxious that the rebels should not take the initiative in the morning, and therefore ordered Hancock to make an assault at 4.30 o'clock.

Meade asked to have the hour changed to six.

Deferring to his wishes as far as I was willing, the order was modified and five was fixed as the hour to move.
Hancock had now fully one-half of the Army of the Potomac.

Wadsworth with his division, which had arrived the night before, lay in a line perpendicular to that held by Hill, and to the right of Hancock.

He was directed to move at the same time, and to attack Hill's left.
Burnside, who was coming up with two divisions, was directed to get in between Warren and Wadsworth, and attack as soon as he could get in position to do so.
