They then brought up some artillery and opened fire against Slocum's position on the crest of the hill.

Failing to make any impression they soon retired and all was quiet once more.
The enemy soon posted batteries on the high ground a mile east of Chancellorsville, and opened on Hancock's front with considerable effect.

They also enfiladed Geary's division of Slocum's corps, and became very annoying, but Knap's battery of the Twelfth Corps replied effectively and kept their fire down to a great extent.
As the Union army was hidden by a thick undergrowth, Lee spent the rest of the day in making a series of feigned attacks to ascertain where our troops were posted.
When night set in, the sound of the axe was heard in every direction, for both armies thought it prudent to strengthen their front as much as possible.
The prospect for Lee as darkness closed over the scene was far from encouraging.

He had examined the position of the Union army carefully, and had satisfied himself that as regards its centre and left it was unassailable.

Let any man with a musket on his shoulder, encumbered with a cartridge-box, haversack, canteen, etc., attempt to climb over a body of felled timber to get at an enemy who is coolly shooting at him from behind a log breastwork, and he will realize the difficulty of forcing a way through such obstacles.
