came in that the Federals were crossing the Antietam near Pry's Mill.
Lee at once ordered Longstreet to meet this threat with Hood's
division, and Jackson was ordered into line on the left of Hood. No
serious collision, however, took place during the evening. The
Confederates made no attempt to oppose the passage of the Creek.
Hood's pickets were driven in, but a speedy reinforcement restored
the line, and except that the batteries on both sides took part the
fighting was little more than an affair of outposts. At eleven
o'clock Hood's brigades were withdrawn to cook and eat. Jackson's
division filled their place; and the night, although broken by
constant alarms, passed away without further conflict. The Federal
movements had clearly exposed their intention of attacking, and had
even revealed the point which they would first assail. McClellan had
thrown two army corps, the First under Hooker, and the Twelfth under
Mansfield, across the Antietam; and they were now posted, facing
southward, a mile and a half north of Sharpsburg, concealed by the
wood beyond Jackson's left.

NOTE.

The essential paragraphs of the lost order ran as follows:--

"The army will resume its march to-morrow, taking the Hagerstown
road. General Jackson's command will form the advance, and after
passing Middletown, with such portions as he may select, take the
route towards Sharpsburg, cross the Potomac at the most convenient
point, and by Friday night (September 12) take possession of the
Baltimore and Ohio Railroad, capture such of the enemy as may be at
Martinsburg, and intercept such as may attempt to escape from
Harper's Ferry.

"General Longstreet's command will pursue the same road as far as
Boonsboro', where it will halt with the reserve, supply, and baggage
trains of the army.

"General McLaws, with his own division and that of General Anderson,
will follow General Longstreet; on reaching Middletown he will take
the route to Harper's Ferry, and by Friday morning (September 12)
possess himself of the Maryland Heights and endeavour to capture the
enemy at Harper's Ferry and vicinity.

"General Walker with his division...will take possession of the
Loudoun Heights, if practicable by Friday morning (September 12),
...He will as far as practicable co-operate with General McLaws and
General Jackson in intercepting the retreat of the enemy.

"General D.H. Hill's division will form the rear-guard of the army,
pursuing the road ta
